示例

下面的示例演示如何创建CultureInfo西班牙语 (西班牙) 与国际排序,另一个对象CultureInfo使用传统排序的对象。The following example shows how to create a CultureInfo object for Spanish (Spain) with the international sort and another CultureInfo object with the traditional sort.

using namespace System;
using namespace System::Collections;
using namespace System::Globalization;
int main()
{
   
   // Creates and initializes the CultureInfo which uses the international sort.
   CultureInfo^ myCIintl = gcnew CultureInfo( "es-ES",false );
   
   // Creates and initializes the CultureInfo which uses the traditional sort.
   CultureInfo^ myCItrad = gcnew CultureInfo( 0x040A,false );
   
   // Displays the properties of each culture.
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "PROPERTY", "INTERNATIONAL", "TRADITIONAL" );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "CompareInfo", myCIintl->CompareInfo, myCItrad->CompareInfo );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "DisplayName", myCIintl->DisplayName, myCItrad->DisplayName );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "EnglishName", myCIintl->EnglishName, myCItrad->EnglishName );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "IsNeutralCulture", myCIintl->IsNeutralCulture, myCItrad->IsNeutralCulture );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "IsReadOnly", myCIintl->IsReadOnly, myCItrad->IsReadOnly );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "LCID", myCIintl->LCID, myCItrad->LCID );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "Name", myCIintl->Name, myCItrad->Name );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "NativeName", myCIintl->NativeName, myCItrad->NativeName );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "Parent", myCIintl->Parent, myCItrad->Parent );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "TextInfo", myCIintl->TextInfo, myCItrad->TextInfo );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "ThreeLetterISOLanguageName", myCIintl->ThreeLetterISOLanguageName, myCItrad->ThreeLetterISOLanguageName );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "ThreeLetterWindowsLanguageName", myCIintl->ThreeLetterWindowsLanguageName, myCItrad->ThreeLetterWindowsLanguageName );
   Console::WriteLine( "{0,-31}{1,-47}{2,-25}", "TwoLetterISOLanguageName", myCIintl->TwoLetterISOLanguageName, myCItrad->TwoLetterISOLanguageName );
   Console::WriteLine();

   Console::WriteLine( "Comparing \"llegar\" and \"lugar\"" );
   Console::WriteLine( "   With myCIintl -> CompareInfo -> Compare: {0}", myCIintl->CompareInfo->Compare( "llegar", "lugar" ) );
   Console::WriteLine( "   With myCItrad -> CompareInfo -> Compare: {0}", myCItrad->CompareInfo->Compare( "llegar", "lugar" ) );
}

注解

CultureInfo类提供特定于区域性的信息,如语言、 子语言、 国家/地区、 日历和与特定区域性关联的约定。The CultureInfo class provides culture-specific information, such as the language, sublanguage, country/region, calendar, and conventions associated with a particular culture. 此类还提供对特定于区域性的实例的访问DateTimeFormatInfoNumberFormatInfoCompareInfo,和TextInfo对象。This class also provides access to culture-specific instances of the DateTimeFormatInfo, NumberFormatInfo, CompareInfo, and TextInfo objects. 这些对象包含特定于区域性的操作,如大小写、 格式化日期和数字,并比较字符串所需的信息。These objects contain the information required for culture-specific operations, such as casing, formatting dates and numbers, and comparing strings. CultureInfo类由直接或间接类设置的格式、 分析,或处理特定于区域性的数据,如StringDateTimeDateTimeOffset,与数值类型。The CultureInfo class is used either directly or indirectly by classes that format, parse, or manipulate culture-specific data, such as String, DateTime, DateTimeOffset, and the numeric types.

区域性名称和标识符Culture names and identifiers

CultureInfo类指定为每个区域性,基于 RFC 4646 的唯一名称。The CultureInfo class specifies a unique name for each culture, based on RFC 4646. 名称是与语言相关的 ISO 639 双小写字母的区域性代码和与国家或地区相关的 ISO 3166 双字母的大写字母子区域性代码的组合。The name is a combination of an ISO 639 two-letter lowercase culture code associated with a language and an ISO 3166 two-letter uppercase subculture code associated with a country or region. 此外,对于面向应用.NET Framework 4.NET Framework 4或更高版本并在 Windows 10 或更高版本,对应于有效的 BCP-47 语言标记受支持的区域性名称运行。In addition, for apps that target .NET Framework 4.NET Framework 4 or later and are running under Windows 10 or later, culture names that correspond to valid BCP-47 language tags are supported.

备注

当区域性名称传递给类构造函数或方法诸如CreateSpecificCultureCultureInfo,其大小写并不重要。When a culture name is passed to a class constructor or a method such as CreateSpecificCulture or CultureInfo, its case is not significant.

根据 RFC 4646 的区域性名称的格式是languagecode2>-country/regioncode2,其中languagecode2是两个字母的语言代码并country/regioncode2是两个字母子区域性代码。The format for the culture name based on RFC 4646 is languagecode2>-country/regioncode2, where languagecode2 is the two-letter language code and country/regioncode2 is the two-letter subculture code. 示例包括 JA-JP 日语 (日本) 和美国英语 (美国)。Examples include ja-JP for Japanese (Japan) and en-US for English (United States). 在两个字母的语言代码不可用的情况下,使用派生自 ISO 639-2 的三个字母代码。In cases where a two-letter language code is not available, a three-letter code derived from ISO 639-2 is used.

请注意,某些区域性名称还指定 ISO 15924 书写符号。Note that some culture names also specify an ISO 15924 script. 例如,符号指定西里尔语脚本和 Latn 指定拉丁语脚本。For example, Cyrl specifies the Cyrillic script and Latn specifies the Latin script. 包含的脚本的区域性名称使用模式languagecode2-scripttag-country/regioncode2A culture name that includes a script uses the pattern languagecode2-scripttag-country/regioncode2. 这种类型的区域性名称的一个示例是 uz 符号-UZ 为乌兹别克语 (西里尔文,乌兹别克斯坦)。An example of this type of culture name is uz-Cyrl-UZ for Uzbek (Cyrillic, Uzbekistan). 在 Windows Vista 之前的 Windows 操作系统,包括脚本的区域性名称使用模式languagecode2-country/regioncode2 - scripttag,例如,uz UZ-符号的乌兹别克语 (西里尔文,乌兹别克斯坦)。On Windows operating systems before Windows Vista, a culture name that includes a script uses the pattern languagecode2-country/regioncode2-scripttag, for example, uz-UZ-Cyrl for Uzbek (Cyrillic, Uzbekistan).

只有两个字母的小写字母语言代码指定一个非特定区域性。A neutral culture is specified by only the two-letter lowercase language code. 例如,fr 为法语,指定的非特定区域性,de 代表德语指定非特定区域性。For example, fr specifies the neutral culture for French, and de specifies the neutral culture for German.

备注

有两个区域性名称不符合此规则。There are two culture names that contradict this rule. 区域性中文 (简体)-Zh-hans,名为和中文 (繁体),名为 Zh-hant,是非特定区域性。The cultures Chinese (Simplified), named zh-Hans, and Chinese (Traditional), named zh-Hant, are neutral cultures. 区域性名称表示当前的标准,并且应使用,除非使用旧名称 ZH-CHS 和 ZH-CHT 的理由需要。The culture names represent the current standard and should be used unless you have a reason for using the older names zh-CHS and zh-CHT.

区域性标识符是标准的国际号码缩写,具有唯一标识的已安装的区域性之一的所需的组件。A culture identifier is a standard international numeric abbreviation and has the components necessary to uniquely identify one of the installed cultures. 你的应用程序可以使用预定义的区域性标识符,或定义自定义的标识符。Your application can use predefined culture identifiers or define custom identifiers.

某些预定义的区域性名称和标识符使用的此类和中的其他类System.Globalization命名空间。Certain predefined culture names and identifiers are used by this and other classes in the System.Globalization namespace. Windows 系统的详细的区域性信息,请参阅语言标记中的列支持的 Windows 的语言/区域名称的列表For detailed culture information for Windows systems, see the Language tag column in the list of language/region names supported by Windows. 区域性名称遵循由定义的标准BCP 47Culture names follow the standard defined by BCP 47.

请记住的区域性名称和标识符表示可在特定计算机找到的区域性的一个子集。Remember that the culture names and identifiers represent only a subset of cultures that can be found on a particular computer. Windows 版本或 service pack 可以更改的可用区域性。Windows versions or service packs can change the available cultures. 应用程序添加自定义区域性使用CultureAndRegionInfoBuilder类。Applications add custom cultures using the CultureAndRegionInfoBuilder class. 用户将添加使用 Microsoft Locale Builder 工具自己自定义区域性。Users add their own custom cultures using the Microsoft Locale Builder tool. Microsoft Locale Builder 编写在托管的代码中使用CultureAndRegionInfoBuilder类。Microsoft Locale Builder is written in managed code using the CultureAndRegionInfoBuilder class.

多个不同的名称是一种文化,值得注意的是与以下的类成员关联的名称与紧密关联:Several distinct names are closely associated with a culture, notably the names associated with the following class members:

不变、 中立和特定区域性Invariant, neutral, and specific cultures

区域性通常分为三个集合: 固定区域性、 非特定区域性和特定区域性。The cultures are generally grouped into three sets: invariant cultures, neutral cultures, and specific cultures.

固定区域性是不区分区域性的。An invariant culture is culture-insensitive. 你的应用程序指定固定区域性的名称使用空字符串 ("") 或由其标识符。Your application specifies the invariant culture by name using an empty string ("") or by its identifier. InvariantCulture 定义固定区域性的实例。InvariantCulture defines an instance of the invariant culture. 它是关联与英语语言,但不能与任何国家/地区。It is associated with the English language but not with any country/region. 几乎所有方法中使用Globalization要求区域性的命名空间。It is used in almost any method in the Globalization namespace that requires a culture.

非特定区域性是关联的区域性与一种语言,但不能与国家/地区。A neutral culture is a culture that is associated with a language but not with a country/region. 特定区域性是一个区域性与一种语言和国家/地区相关联。A specific culture is a culture that is associated with a language and a country/region. 例如,fr 是法语区域的非特定语言名称和 FR-FR 是特定的法语 (法国) 区域性的名称。For example, fr is the neutral name for the French culture, and fr-FR is the name of the specific French (France) culture. 请注意,中文 (简体) 和中文 (繁体) 也被视为非特定区域性。Note that Chinese (Simplified) and Chinese (Traditional) are also considered neutral cultures.

创建实例的CompareInfo类不建议一个非特定区域性,因为其包含的数据是任意的。Creating an instance of a CompareInfo class for a neutral culture is not recommended because the data it contains is arbitrary. 若要显示和对数据进行排序,指定的语言和区域。To display and sort data, specify both the language and region. 此外,Name属性的CompareInfo对象创建一个非特定区域性返回仅的国家/地区,并且不包含区域。Additionally, the Name property of a CompareInfo object created for a neutral culture returns only the country and does not include the region.

定义的区域性具有层次结构中的特定区域性的父级是一个非特定区域性和非特定区域性的父级是固定的区域性。The defined cultures have a hierarchy in which the parent of a specific culture is a neutral culture and the parent of a neutral culture is the invariant culture. Parent属性包含与特定区域性关联的非特定区域性。The Parent property contains the neutral culture associated with a specific culture. 自定义区域性应Parent为了符合此模式的属性。Custom cultures should define the Parent property in conformance with this pattern.

如果针对特定区域性资源不可用在操作系统中,将使用关联的非特定区域性的资源。If the resources for a specific culture are not available in the operating system, the resources for the associated neutral culture are used. 如果非特定区域性资源不可用,则使用嵌入在主程序集中的资源。If the resources for the neutral culture are not available, the resources embedded in the main assembly are used. 资源回退进程的详细信息,请参阅打包和部署资源For more information on the resource fallback process, see Packaging and Deploying Resources.

Windows API 中的区域设置的列表是略有不同的.NET Framework 支持的区域性列表。The list of locales in the Windows API is slightly different from the list of cultures supported by the .NET Framework. 如果需要与 Windows 互操作性,例如,通过 p/invoke 机制,应用程序应使用特定区域性定义的操作系统。If interoperability with Windows is required, for example, through the p/invoke mechanism, the application should use a specific culture that is defined for the operating system. 使用特定区域性可确保与等效的 Windows 区域设置,会使用相同的区域设置标识符来标识的一致性LCIDUse of the specific culture ensures consistency with the equivalent Windows locale, which is identified with a locale identifier that is the same as LCID.

一个DateTimeFormatInfoNumberFormatInfo可以创建仅用于固定区域性或特定区域性,不能为非特定区域性。A DateTimeFormatInfo or a NumberFormatInfo can be created only for the invariant culture or for specific cultures, not for neutral cultures.

如果DateTimeFormatInfo.CalendarTaiwanCalendarThread.CurrentCulture未设置为 ZH-TW,然后DateTimeFormatInfo.NativeCalendarNameDateTimeFormatInfo.GetEraName,并DateTimeFormatInfo.GetAbbreviatedEraName返回空字符串 ("")。If DateTimeFormatInfo.Calendar is the TaiwanCalendar but the Thread.CurrentCulture is not set to zh-TW, then DateTimeFormatInfo.NativeCalendarName, DateTimeFormatInfo.GetEraName, and DateTimeFormatInfo.GetAbbreviatedEraName return an empty string ("").

自定义区域性Custom cultures

除了 Windows 操作系统和.NET Framework 支持的预定义区域性,.NET Framework 支持三种类型的自定义区域性:In addition to the predefined cultures supported by the Windows operating system and the .NET Framework, the .NET Framework supports three types of custom cultures:

  • 新补充 Windows 或.NET Framework 中可用的区域性的区域性。New cultures that supplement the cultures available in Windows or the .NET Framework. 例如,应用程序无法安装CultureInfo表示 FJ-FJ (或 Fijan (斐济)) 区域性的系统上的对象。For example, an application could install a CultureInfo object that represents the fj-FJ (or Fijan (Fiji)) culture on a system.

  • 其属性是不同于 Windows 和.NET Framework 支持标准区域性的属性的替换区域性。Replacement cultures whose properties are different from the properties of the standard cultures supported by Windows and the .NET Framework.

  • 通过用户重写的标准区域性。Standard cultures with user overrides. 用户可以使用区域和语言应用程序中控制面板自定义现有区域性的属性值。The user can use the Region and Language application in Control Panel to customize an existing culture's property values.

备注

可以使用CultureAndRegionInfoBuilder类来定义、 保存和注册自定义区域性的补充或替换现有的区域性。You can use the CultureAndRegionInfoBuilder class to define, save, and register custom cultures that either supplement or replace existing cultures. CultureAndRegionInfoBuilder.Save方法将创建可用于在目标系统上安装自定义区域性的区域设置数据标记语言 (LDML) 文件。The CultureAndRegionInfoBuilder.Save method creates a Locale Data Markup Language (LDML) file that can be used to install a custom culture on target systems. 有关分步步骤使用信息CultureAndRegionInfoBuilder要创建一个新类或替换区域性,请参阅CultureAndRegionInfoBuilder类主题。For step-by step information on using the CultureAndRegionInfoBuilder class to create a new or replacement culture, see the CultureAndRegionInfoBuilder class topic.

由于.NET Framework 支持自定义区域性,使用特定于区域性的数据时应考虑以下:Because the .NET Framework supports custom cultures, you should consider the following when working with culture-specific data:

  • 自定义区域性可以有超过预定义的区域性的范围的值。Custom cultures can have values that exceed the ranges of the predefined cultures. 例如,某些区域性具有非常长月份名称、 意外的日期或时间格式或其他不常见的数据。For example, some cultures have unusually long month names, unexpected date or time formats, or other unusual data.

  • 当在用户界面中显示特定于区域性的数据时,应遵守用户的自定义项;例如,用户可能希望采用 24 小时制或 yyyyMMdd 日期格式。When you display culture-specific data in the user interface, you should respect the user's customizations; for example, the user might want a 24-hour clock or a yyyyMMdd date format.

  • 请记住,自定义区域性重写默认值。Remember that custom cultures override default values. 因此,不能考虑区域性数据保持不变。Therefore, you cannot consider culture data to be stable. 在将来可能会更改国家/地区名称、 数字和日期格式和拼写。Country names, number and date formats, and spellings may change in the future. 如果你想要序列化区分区域性的数据,如要传递到的日期和时间分析函数的日期和时间字符串,应使用固定区域性或特定。If you want to serialize culture-sensitive data such as date and time strings to be passed to the date and time parsing functions, you should use the invariant culture or a specific .

CultureTypes的系统上安装的自定义区域性的属性值包含System.Globalization.CultureTypes分配标志和自定义区域性LCID属性值为LOCALE_CUSTOM_UNSPECIFIED(0x1000 控制或 4096)。The CultureTypes property value of custom cultures installed on a system includes the System.Globalization.CultureTypes flag, and custom cultures are assigned an LCID property value of LOCALE_CUSTOM_UNSPECIFIED (0x1000, or 4096). 请注意,从 Windows 10 开始,此值也分配给缺少完整的文化数据的系统定义的区域性。Note that, starting with Windows 10, this value is also assigned to system-defined cultures that lack complete cultural data.

CultureInfo 和文化的数据CultureInfo and cultural data

.NET 派生其区域性的数据从各种源,具体取决于实现、 平台和版本的一个:.NET derives its cultural data from a one of a variety of sources, depending on implementation, platform, and version:

  • 在.NET Framework 3.5 和更早版本中,区域性数据是由 Windows 操作系统和.NET Framework 提供的。In .NET Framework 3.5 and earlier versions, cultural data is provided by both the Windows operating system and the .NET Framework.

  • 在.NET Framework 4 和更高版本中,由 Windows 操作系统提供区域性的数据。In .NET Framework 4 and later versions, cultural data is provided by the Windows operating system.

  • 在所有版本的.NET Core 在 Windows 上运行,由 Windows 操作系统提供区域性的数据。In all versions of .NET Core running on Windows, cultural data is provided by the Windows operating system.

  • 在所有版本的 Unix 平台上运行的.NET Core,区域性数据由提供International Components for Unicode (ICU) 库In all versions of .NET Core running on Unix platforms, cultural data is provided by the International Components for Unicode (ICU) Library. ICU 库的特定版本取决于各个操作系统。The specific version of the ICU Library depends on the individual operating system.

因此,可在特定.NET 实现、 平台或版本上的区域性可能不可用不同.NET 实现、 平台或版本上。Because of this, a culture available on a particular .NET implementation, platform, or version may not be available on a different .NET implementation, platform, or version.

某些CultureInfo对象存在差异,具体取决于基础平台。Some CultureInfo objects differ depending on the underlying platform. 具体而言,"zh CN",或中文 (简体,中国) 和 ZH-TW,或中文 (繁体,台湾) 是 Windows 系统上的可用区域性,但它们是在 Unix 系统上的使用别名区域性。In particular, "zh-CN", or Chinese (Simplified, China) and zh-TW, or Chinese (Traditional, Taiwan), are available cultures on Windows systems, but they are aliased cultures on Unix systems. "zh CN"是"zh Hans CN"区域性的别名和"ZH-TW"是"不同-ZH-TW"区域性的别名。"zh-CN" is an alias for the "zh-Hans-CN" culture, and "zh-TW" is an alias for the "zh-Hant-TW" culture. 使用别名的区域性不返回通过调用GetCultures方法并且可能具有不同的属性值,包括不同Parent比对应的 Windows 的区域性。Aliased cultures are not returned by calls to the GetCultures method and may have different property values, including different Parent cultures, than their Windows counterparts. 对于 ZH-CN 和 ZH-TW 的区域性,这些 differenes 包括:For the zh-CN and zh-TW cultures, these differenes include the following:

  • 在 Windows 系统上的"zh CN"区域性的父区域性"Zh-hans","ZH-TW"区域性的父区域性"Zh-hant"。On Windows systems, the parent culture of the "zh-CN" culture is "zh-Hans", and the parent culture of the "zh-TW" culture is "zh-Hant". 这两个这些区域性的父区域性是"zh"。The parent culture of both these cultures is "zh". 在 Unix 系统上的这两个区域性父级的"zh"。On Unix systems, the parents of both cultures are "zh". 这意味着,如果没有为"zh CN"或"ZH-TW"区域性提供特定于区域性的资源,但不要为非特定语言"-Zh-hans"或"Zh-hant"区域性提供资源,你的应用程序将加载在 Windows 上,但不是在 Unix 上的非特定区域性的资源.This means that, if you don't provide culture-specific resources for the "zh-CN" or "zh-TW" cultures but do provide a resources for the neutral "zh-Hans" or "zh-Hant" culture, your application will load the resources for the neutral culture on Windows but not on Unix. 在 Unix 系统中,您必须显式设置线程的CurrentUICulture"Zh-hans"或"Zh-hant"。On Unix systems, you must explicitly set the thread's CurrentUICulture to either "zh-Hans" or "zh-Hant".

  • 在 Windows 系统中,调用CultureInfo.Equals实例上表示"zh CN"区域性,并将其传递"zh Hans CN"实例返回trueOn Windows systems, calling CultureInfo.Equals on an instance that represents the "zh-CN" culture and passing it a "zh-Hans-CN" instance returns true. 在 Unix 系统上的方法调用返回falseOn Unix systems, the method call returns false. 此行为也适用于调用Equals上"ZH-TW"CultureInfo实例并将其传递"不同-Zh-tw"实例。This behavior also applies to calling Equals on a "zh-TW" CultureInfo instance and passing it a "zh-Hant-Tw" instance.

动态区域性数据Dynamic culture data

固定区域性,除区域性数据是动态的。Except for the invariant culture, culture data is dynamic. 这是即使对于预定义的区域性,则返回 true。This is true even for the predefined cultures. 例如,国家或地区采用新的货币、 更改其拼写的单词,或更改其首选的日历和区域性定义更改跟踪此事件。For example, countries or regions adopt new currencies, change their spellings of words, or change their preferred calendar, and culture definitions change to track this. 自定义区域性可能会有所变动,恕不另行通知,和任何特定区域性可能会被重写通过自定义替换区域性。Custom cultures are subject to change without notice, and any specific culture might be overridden by a custom replacement culture. 此外,按如下所述,为单个用户可以重写区域首选项。Also, as discussed below, an individual user can override cultural preferences. 应用程序应始终在运行时获取区域性的数据。Applications should always obtain culture data at run time.

注意

保存数据时,应用程序应使用固定区域性、 二进制格式或特定于区域性的格式。When saving data, your application should use the invariant culture, a binary format, or a specific culture-independent format. 根据特定区域性,而非固定区域性,与关联的当前值保存数据可能会变得不可读,或如果该区域性发生更改的含义可能会更改。Data saved according to the current values associated with a particular culture, other than the invariant culture, might become unreadable or might change in meaning if that culture changes.

当前区域性和当前 UI 区域性The current culture and current UI culture

在.NET 应用程序中的每个线程都具有当前区域性和当前 UI 区域性。Every thread in a .NET application has a current culture and a current UI culture. 当前区域性的日期、 时间、 数字和货币值、 文本、 大小写约定和比较字符串的方法的排序顺序确定的格式设置约定。The current culture determines the formatting conventions for dates, times, numbers, and currency values, the sort order of text, casing conventions, and the ways in which strings are compared. 当前 UI 区域性用于检索在运行时特定于区域性的资源。The current UI culture is used to retrieve culture-specific resources at runtime.

备注

有关如何针对每个线程确定当前和当前 UI 区域性的信息,请参阅区域性和线程部分。For information on how the current and current UI culture is determined on a per-thread basis, see the Culture and threads section. 了解如何将当前和当前 UI 区域性确定线程上执行新的应用程序域,并跨应用程序域边界的线程上请参阅区域性和应用程序域部分。For information on how the current and current UI culture is determined on threads executing in a new application domain, and on threads that cross application domain boundaries, see the Culture and application domains section. 有关如何执行基于任务的异步操作的线程上确定当前的和当前的信息,请参阅区域性和基于任务的异步操作部分。For information on how the current and current is determined on threads performing task-based asynchronous operations, see the Culture and task-based asynchronous operations section.

有关详细的当前区域性的信息,请参阅CultureInfo.CurrentCulture属性主题。For more detailed information on the current culture, see the CultureInfo.CurrentCulture property topic. 有关详细的当前 UI 区域性的信息,请参阅CultureInfo.CurrentUICulture属性主题。For more detailed information on the current UI culture, see the CultureInfo.CurrentUICulture property topic.

设置当前和当前 UI 区域性Setting the current and current UI cultures

若要更改区域性和 UI 线程的区域性,请执行以下操作:To change the culture and UI culture of a thread, do the following:

  1. 实例化CultureInfo对象,通过调用表示该区域性CultureInfo类构造函数并将其传递区域性的名称。Instantiate a CultureInfo object that represents that culture by calling a CultureInfo class constructor and passing it the name of the culture. CultureInfo(String)构造函数实例化CultureInfo反映用户的对象重写的新区域性是否与当前的 Windows 区域性相同。The CultureInfo(String) constructor instantiates a CultureInfo object that reflects user overrides if the new culture is the same as the current Windows culture. CultureInfo(String, Boolean)构造函数允许您指定是否新实例化CultureInfo对象反映用户替代新区域性是否与当前的 Windows 区域性相同。The CultureInfo(String, Boolean) constructor allows you to specify whether the newly instantiated CultureInfo object reflects user overrides if the new culture is the same as the current Windows culture.

  2. 将分配CultureInfo对象传递给CultureInfo.CurrentCultureCultureInfo.CurrentUICulture.NET Core 和.NET Framework 4.6 和更高版本上的属性。Assign the CultureInfo object to the CultureInfo.CurrentCulture or CultureInfo.CurrentUICulture property on .NET Core and .NET Framework 4.6 and later versions. (在.NET Framework 4.5.2 及早期版本中,分配 youcCultureInfo对象传递给Thread.CurrentCultureThread.CurrentUICulture属性。)(On .NET Framework 4.5.2 and earlier versions, youc an assign the CultureInfo object to the Thread.CurrentCulture or Thread.CurrentUICulture property.)

下面的示例检索当前区域性。The following example retrieves the current culture. 如果是法语 (法国) 区域性之外的任何内容,但它会将当前区域性更改为法语 (法国)。If it is anything other than the French (France) culture, it changes the current culture to French (France). 否则,它将当前区域性更改为法语 (卢森堡)。Otherwise, it changes the current culture to French (Luxembourg).

当启动新的应用程序线程时,其当前区域性和当前 UI 区域性定义由当前系统区域性,而不是当前线程区域性。When a new application thread is started, its current culture and current UI culture are defined by the current system culture, and not by the current thread culture. 以下示例演示了差异。The following example illustrates the difference. 它将当前区域性和应用程序线程的当前 UI 区域性设置为法语 (法国) 区域性 (FR-FR)。It sets the current culture and current UI culture of an application thread to the French (France) culture (fr-FR). 如果当前区域性已经-FR,该示例会将其设置为英语 (美国) 区域性 (EN-US)。If the current culture is already fr-FR, the example sets it to the English (United States) culture (en-US). 它显示为货币值的三个随机数字,然后创建一个新线程,后者又将三个更随机数字显示为货币值。It displays three random numbers as currency values and then creates a new thread, which, in turn, displays three more random numbers as currency values. 但如中的示例所示的输出,显示由新线程的货币值不能反映法语 (法国) 区域性,与主应用程序线程的输出不同的格式设置约定。But as the output from the example shows, the currency values displayed by the new thread do not reflect the formatting conventions of the French (France) culture, unlike the output from the main application thread.

在之前的.NET framework 版本.NET Framework 4.5.NET Framework 4.5、 最常用的方法,以确保主应用程序线程与所有其他工作线程共享相同的区域性是传递的应用程序范围内区域性名称或CultureInfo对象表示的应用程序范围内区域性System.Threading.ParameterizedThreadStart委托。In versions of the .NET Framework before the .NET Framework 4.5.NET Framework 4.5, the most common way to ensure that the main application thread shares the same culture with all other worker threads is to pass either the name of the application-wide culture or a CultureInfo object that represents the application-wide culture to a System.Threading.ParameterizedThreadStart delegate. 以下示例使用此方法以确保显示由两个线程的货币值反映相同的区域性的格式设置约定。The following example uses this approach to ensure that the currency values displayed by two threads reflect the formatting conventions of the same culture.

您可以设置区域性和 UI 区域性的线程池线程中类似的方式通过调用ThreadPool.QueueUserWorkItem(WaitCallback, Object)方法。You can set the culture and UI culture of thread pool threads in a similar manner by calling the ThreadPool.QueueUserWorkItem(WaitCallback, Object) method.

从开始.NET Framework 4.5.NET Framework 4.5,你可以设置区域性和 UI 区域性,所有线程的应用程序域中更直接地通过分配CultureInfo对象,表示该区域性DefaultThreadCurrentCultureDefaultThreadCurrentUICulture属性。Starting with the .NET Framework 4.5.NET Framework 4.5, you can set the culture and UI culture of all threads in an application domain more directly by assigning a CultureInfo object that represents that culture to the DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture properties. 下面的示例使用这些属性以确保在默认应用程序域中的所有线程都共享相同的区域性。The following example uses these properties to ensure that all threads in the default application domain share the same culture.

警告

尽管DefaultThreadCurrentCultureDefaultThreadCurrentUICulture属性是静态成员,它们定义的默认区域性和仅适用于应用程序域的当前设置这些属性值时的默认 UI 区域性。Although the DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture properties are static members, they define the default culture and default UI culture only for the application domain that is current at the time these property values are set. 有关详细信息,请参阅下一部分中,区域性和应用程序域For more information, see the next section, Culture and application domains.

在分配到的值DefaultThreadCurrentCultureDefaultThreadCurrentUICulture属性、 区域性和 UI 区域性的应用程序域中线程还更改如果它们未显式分配区域性。When you assign values to the DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture properties, the culture and UI culture of the threads in the application domain also change if they have not explicitly been assigned a culture. 但是,这些线程反映新的区域性设置,仅当它们在当前应用程序域中执行时。However, these threads reflect the new culture settings only while they execute in the current application domain. 如果在另一个应用程序域中执行这些线程,其区域性将成为该应用程序域定义的默认区域性。If these threads execute in another application domain, their culture becomes the default culture defined for that application domain. 因此,我们建议你始终将主应用程序线程的区域性设置而不依赖DefaultThreadCurrentCultureDefaultThreadCurrentUICulture属性以更改它。As a result, we recommend that you always set the culture of the main application thread, and not rely on the DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture properties to change it.

区域性和应用程序域Culture and application domains

DefaultThreadCurrentCultureDefaultThreadCurrentUICulture是显式定义仅适用于时设置或检索属性值的当前应用程序域默认区域性的静态属性。DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture are static properties that explicitly define a default culture only for the application domain that is current when the property value is set or retrieved. 下面的示例将默认应用程序域中的默认区域性和默认 UI 区域性设置为法语 (法国),然后使用AppDomainSetup类和AppDomainInitializer委托到一个新应用程序域中设置的默认区域性和 UI 区域性俄语 (俄罗斯)。The following example sets the default culture and default UI culture in the default application domain to French (France), and then uses the AppDomainSetup class and the AppDomainInitializer delegate to set the default culture and UI culture in a new application domain to Russian (Russia). 单个线程然后执行每个应用程序域中的两种方法。A single thread then executes two methods in each application domain. 请注意,线程的区域性和 UI 区域性没有显式设置;它们派生自的默认区域性和 UI 区域性,线程执行所在的应用程序域。Note that the thread's culture and UI culture are not explicitly set; they are derived from the default culture and UI culture of the application domain in which the thread is executing. 另请注意DefaultThreadCurrentCultureDefaultThreadCurrentUICulture属性返回的默认CultureInfo进行方法调用时的当前应用程序域的值。Note also that the DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture properties return the default CultureInfo values of the application domain that is current when the method call is made.

区域性和基于任务的异步操作Culture and task-based asynchronous operations

基于任务的异步编程模式使用TaskTask<TResult>线程池线程对象上异步执行委托。The task-based asynchronous programming pattern uses Task and Task<TResult> objects to asynchronously execute delegates on thread pool threads. 运行特定任务的特定线程不提前已知,但仅在运行时确定。The specific thread on which a particular task runs is not known in advance, but is determined only at runtime.

对于面向应用.NET Framework 4.6.NET Framework 4.6或更高版本、 区域性是一个异步操作的上下文的一部分。For apps that target the .NET Framework 4.6.NET Framework 4.6 or later versions, culture is part of an asynchronous operation's context. 换而言之,应用程序起面向.NET Framework 4.6.NET Framework 4.6,默认情况下异步操作继承的值CurrentCultureCurrentUICulture从中启动的线程的属性。In other words, starting with apps that target the .NET Framework 4.6.NET Framework 4.6, asynchronous operations by default inherit the values of the CurrentCulture and CurrentUICulture properties of the thread from which they are launched. 如果当前区域性或当前 UI 区域性不同于系统区域性,当前区域性跨线程边界的部署,并将成为当前正在执行异步操作的线程池线程的区域性。If the current culture or current UI culture differs from the system culture, the current culture crosses thread boundaries and becomes the current culture of the thread pool thread that is executing an asynchronous operation.

下面的示例提供了简单的演示。The following example provides a simple illustration. 它使用TargetFrameworkAttribute属性设置为目标.NET Framework 4.6.NET Framework 4.6It uses the TargetFrameworkAttribute attribute to target the .NET Framework 4.6.NET Framework 4.6. 该示例定义了Func<TResult>委派, formatDelegate,返回一些数字格式化为货币值。The example defines a Func<TResult> delegate, formatDelegate, that returns some numbers formatted as currency values. 该示例将当前系统区域性更改为 French (France) 或法语 (法国) 已为当前区域性,英语 (美国)。The example changes the current system culture to either French (France) or, if French (France) is already the current culture, English (United States). 然后它:It then:

  • 直接调用委托,以便使其在主应用线程上同步运行。Invokes the delegate directly so that it runs synchronously on the main app thread.

  • 创建线程池线程异步执行委托的任务。Creates a task that executes the delegate asynchronously on a thread pool thread.

  • 创建一个任务,该委托线程上同步执行主应用程序通过调用Task.RunSynchronously方法。Creates a task that executes the delegate synchronously on the main app thread by calling the Task.RunSynchronously method.

如示例输出所示,如果当前区域性更改为法语 (法国) 任务以异步方式调用从该线程的当前区域性将成为该异步操作的当前区域性。As the output from the example shows, when the current culture is changed to French (France), the current culture of the thread from which tasks are invoked asynchronously becomes the current culture for that asynchronous operation.

对于面向版本之前的.NET Framework 的应用, .NET Framework 4.6.NET Framework 4.6,或对于不面向特定版本的.NET framework 的应用,调用线程的区域性不是任务的上下文的一部分。For apps that target versions of the .NET Framework prior to the .NET Framework 4.6.NET Framework 4.6, or for apps that do not target a particular version of the .NET Framework, the culture of the calling thread is not part of a task's context. 相反,除非已显式定义,默认情况下的新线程的区域性是系统区域性。Instead, unless one is explicitly defined, the culture of new threads by default is the system culture. 以下示例中,这是与上一示例相同,不同之处在于它缺少TargetFrameworkAttribute属性,阐释了这一点。The following example, which is identical to the previous example except that it lacks the TargetFrameworkAttribute attribute, illustrates this. 执行示例系统的系统区域性为英语 (美国),因为线程池线程异步执行的区域性是任务的 EN-US 而不是任务的 fr-fr。Because the system culture of the system on which the example executed was English (United States), the culture of the task that executes asynchronously on a thread pool thread is en-US rather than fr-FR.

从.NET Framework 目标版本的应用.NET Framework 4.5.NET Framework 4.5和更高版本,但之前.NET Framework 4.6.NET Framework 4.6,可以使用DefaultThreadCurrentCultureDefaultThreadCurrentUICulture属性以确保调用线程的区域性用于在异步任务在线程池线程上执行。For apps that target versions of the .NET Framework from the .NET Framework 4.5.NET Framework 4.5 and later but prior to the .NET Framework 4.6.NET Framework 4.6, you can use the DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture properties to ensure that the culture of the calling thread is used in asynchronous tasks that execute on thread pool threads. 下面的示例等同于上一示例中,只不过它使用DefaultThreadCurrentCulture属性以确保该线程池线程具有与主应用程序线程相同的区域性。The following example is identical to the previous example, except that it uses the DefaultThreadCurrentCulture property to ensure that thread pool threads have the same culture as the main app thread.

DefaultThreadCurrentCultureDefaultThreadCurrentUICulture是每个应用域的属性; 也就是说,它们建立默认区域性的所有线程都未显式都分配区域性特定的应用程序域中。DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture are per-app domain properties; that is, they establish a default culture for all threads not explicitly assigned a culture in a specific application domain. 但是,对于面向应用.NET Framework 4.6.NET Framework 4.6或更高版本,调用线程的区域性保持异步任务的上下文的一部分,即使跨应用程序域边界的部署任务。However, for apps that target the .NET Framework 4.6.NET Framework 4.6 or later, the culture of the calling thread remains part of an asynchronous task's context even if the task crosses app domain boundaries.

下面的示例显示了调用线程的区域性保持基于任务的异步操作的当前区域性,即使跨应用程序域边界的部署执行该任务的方法。The following example shows that the calling thread's culture remains the current culture of a task-based asynchronous operation even if the method that the task is executing crosses application domain boundaries. 它定义了一个类DataRetriever,使用单个方法GetFormattedNumber,介于 1 和 1000 格式化为货币值之间返回一个随机的双精度浮点数。It defines a class, DataRetriever, with a single method, GetFormattedNumber, that returns a random double-precision floating-point number between 1 and 1,000 formatted as a currency value. 第一个任务运行,只需实例化DataRetriever实例并调用其GetFormattedNumber方法。A first task is run that simply instantiates a DataRetriever instance and calls its GetFormattedNumber method. 第二个任务报告其当前的应用程序域、 创建新的应用程序域、 实例化DataRetriever实例中新的应用程序域,并调用其GetFormattedNumber方法。A second task reports its current application domain, creates a new application domain, instantiates a DataRetriever instance in the new application domain, and calls its GetFormattedNumber method. 如示例输出所示,当前区域性保持在调用线程,第一个任务和第二个任务都相同主应用程序域和第二个应用程序域中执行时。As the output from the example shows, the current culture has remained the same in the calling thread, the first task, and the second task both when it was executing in the main application domain and the second application domain.

CultureInfo 对象序列化CultureInfo object serialization

CultureInfo序列化对象,只实际存储NameUseUserOverrideWhen a CultureInfo object is serialized, all that is actually stored is Name and UseUserOverride. 它是仅在环境中成功反序列其中的Name具有相同的含义。It is successfully de-serialized only in an environment where that Name has the same meaning. 以下三个示例演示这为什么不是始终用例:The following three examples show why this is not always the case:

  • 如果CultureTypes属性值是CultureTypes.InstalledWin32Cultures,和特定版本的 Windows 操作系统中首次引入该区域性,如果不能在早期版本的 Windows 上反序列化。If the CultureTypes property value is CultureTypes.InstalledWin32Cultures, and if that culture was first introduced in a particular version of the Windows operating system, it is not possible to deserialize it on an earlier version of Windows. 例如,如果在 Windows 10 中引入了一个区域性,它不能反序列化在 Windows 8 上。For example, if a culture was introduced in Windows 10, it cannot be deserialized on Windows 8.

  • 如果CultureTypes值是CultureTypes.UserCustomCulture,和它反序列化计算机没有安装此用户自定义区域性,不能以反序列化。If the CultureTypes value is CultureTypes.UserCustomCulture, and the computer on which it is de-serialized does not have this user custom culture installed, it is not possible to deserialize it.

  • 如果CultureTypes值是CultureTypes.ReplacementCultures,和它反序列化计算机不具有此替换区域性,其反序列化为相同的名称,但不是所有相同的特性。If the CultureTypes value is CultureTypes.ReplacementCultures, and the computer on which it is de-serialized does not have this replacement culture, it de-serializes to the same name, but not all of the same characteristics. 例如,EN-US 是否在计算机 A,但不是在计算机 B 上, 一个替换区域性,如果CultureInfo对象引用此区域性是在计算机 A 上序列化和反序列化计算机 B 上则没有区域性的自定义特征传输。For example, if en-US is a replacement culture on computer A, but not on computer B, and if a CultureInfo object referring to this culture is serialized on computer A and de-serialized on computer B, then none of the custom characteristics of the culture are transmitted. 已成功,但具有不同的含义,反序列化的区域性。The culture deserializes successfully, but with a different meaning.

控件面板重写Control Panel overrides

用户可以选择重写一些与 Windows 通过控制面板的区域和语言选项部分的当前区域性关联的值。The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. 例如,用户可以选择以不同格式显示日期,或使用一种货币而不是默认区域性。For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. 一般情况下,您的应用程序应遵循这些用户重写。In general, your applications should honor these user overrides.

如果UseUserOverridetrue和指定的区域性匹配的 Windows,当前区域性CultureInfo使用这些重写值,其中包括用户设置的属性DateTimeFormatInfo返回实例DateTimeFormat属性,和的属性NumberFormatInfo返回实例NumberFormat属性。If UseUserOverride is true and the specified culture matches the current culture of Windows, the CultureInfo uses those overrides, including user settings for the properties of the DateTimeFormatInfo instance returned by the DateTimeFormat property, and the properties of the NumberFormatInfo instance returned by the NumberFormat property. 如果用户设置与不兼容与关联的区域性CultureInfo,例如,如果在所选的日历不是之一OptionalCalendars,方法的结果和属性的值是不确定。If the user settings are incompatible with the culture associated with the CultureInfo, for example, if the selected calendar is not one of the OptionalCalendars, the results of the methods and the values of the properties are undefined.

替代排序顺序Alternate sort orders

一些文化可支持多个排序顺序。Some cultures support more than one sort order. 例如:For example:

  • 西班牙语 (西班牙) 区域性都有两种排序顺序: 默认国际排序顺序和传统的排序顺序。The Spanish (Spain) culture has two sort orders: the default international sort order, and the traditional sort order. 当您实例化CultureInfo对象 ES-ES 区域性名称,则使用国际排序顺序。When you instantiate a CultureInfo object with the es-ES culture name, the international sort order is used. 当您实例化CultureInfo对象具有 es ES tradnl 区域性名称,则使用传统的排序顺序。When you instantiate a CultureInfo object with the es-ES-tradnl culture name, the traditional sort order is used.

  • ZH-CN (中文 (简体,中国)) 区域性支持两种排序顺序: 按发音 (默认值) 和按笔画数。The zh-CN (Chinese (Simplified, PRC)) culture supports two sort orders: by pronunciation (the default) and by stroke count. 当您实例化CultureInfo对象 ZH-CN 区域性名称,则使用默认排序顺序。When you instantiate a CultureInfo object with the zh-CN culture name, the default sort order is used. 当您实例化CultureInfo对象 0x00020804 的本地标识符的字符串按笔画数排序。When you instantiate a CultureInfo object with a local identifier of 0x00020804, strings are sorted by stroke count.

下表列出了支持替代排序顺序和标识符的默认和替代排序顺序的区域性。The following table lists the cultures that support alternate sort orders and the identifiers for the default and alternate sort orders.

当前区域性和 UWP 应用The current culture and UWP apps

在通用 Windows 平台 (UWP) 应用中,CurrentCultureCurrentUICulture属性是读写的就像它们是.NET Framework 和.NET Core 应用程序中。In Universal Windows Platform (UWP) apps, the CurrentCulture and CurrentUICulture properties are read-write, just as they are in .NET Framework and .NET Core apps. 但是,UWP 应用识别单个区域性。However, UWP apps recognize a single culture. CurrentCultureCurrentUICulture属性映射到的第一个值Windows.ApplicationModel.Resources.Core.ResourceManager.DefaultContext.Languages集合。The CurrentCulture and CurrentUICulture properties map to the first value in the Windows.ApplicationModel.Resources.Core.ResourceManager.DefaultContext.Languages collection.

在.NET Framework 和.NET Core 应用程序,当前区域性为每个线程设置,并CurrentCultureCurrentUICulture属性反映了区域性和 UI 区域性的当前线程。In .NET Framework and .NET Core apps, the current culture is a per-thread setting, and the CurrentCulture and CurrentUICulture properties reflect the culture and UI culture of the current thread only. 在 UWP 应用中,当前的区域性将映射到Windows.ApplicationModel.Resources.Core.ResourceManager.DefaultContext.Languages回收,这是一种全局设置。In UWP apps, the current culture maps to the Windows.ApplicationModel.Resources.Core.ResourceManager.DefaultContext.Languages collection, which is a global setting. 设置CurrentCultureCurrentUICulture属性发生更改的整个应用程序的区域性; 不能针对每个线程设置区域性。Setting the CurrentCulture or CurrentUICulture property changes the culture of the entire app; culture cannot be set on a per-thread basis.
