CultureAndRegionInfoBuilder.CreateFromLdml(String) 方法

定义

用一个包含对象表示形式的指定 XML 文件重构 CultureAndRegionInfoBuilder 对象。

public:
 static System::Globalization::CultureAndRegionInfoBuilder ^ CreateFromLdml(System::String ^ xmlFileName);
public static System.Globalization.CultureAndRegionInfoBuilder CreateFromLdml (string xmlFileName);
static member CreateFromLdml : string -> System.Globalization.CultureAndRegionInfoBuilder
Public Shared Function CreateFromLdml (xmlFileName As String) As CultureAndRegionInfoBuilder

参数

xmlFileName
String

一个包含 CultureAndRegionInfoBuilder 对象的 XML 表示形式的文件名。

返回

等效于 xmlFileName 参数中存储的信息的新对象。

例外

xmlFileNamenull

xmlFileName 是一个空字符串 ("") 或者是无效的文件或路径名。

xmlFileName 中的数据不是有效的 XML 格式。

- 或 -

在访问 xmlFileName 时发生 I/O 错误。

xmlFileName 中的数据不是有效的 LDML 格式。

示例

以下示例演示 SaveCreateFromLdml 方法。

// This example demonstrates the CultureAndRegionInfoBuilder.Save and
// CreateFromLdml methods.
// Compile this example with a reference to sysglobl.dll.

using System.Globalization;
using System.IO;
using System.Xml;

class Sample
{
    public static void Main()
    {
    string savedCARIB = "mySavedCARIB.xml";
    string msg1 = "The name of the original CultureAndRegionInfoBuilder" +
                  " is \"{0}\".";
    string msg2 = "Reconstituting the CultureAndRegionInfoBuilder object " +
                  "from \"{0}\".";
    string msg3 = "The name of the reconstituted CultureAndRegionInfoBuilder" +
                  " is \"{0}\".";

// Construct a new, privately used culture that extends the en-US culture
// provided by the .NET Framework. In this sample, the CultureAndRegion-
// Types.Specific parameter creates a minimal CultureAndRegionInfoBuilder
// object that you must populate with culture and region information.

    CultureAndRegionInfoBuilder cib1 = null;
    CultureAndRegionInfoBuilder cib2 = null;
    try {
        cib1 = new CultureAndRegionInfoBuilder(
                           "x-en-US-sample", CultureAndRegionModifiers.None);

    CultureInfo ci = new CultureInfo("en-US");
    cib1.LoadDataFromCultureInfo(ci);

// Populate the new CultureAndRegionInfoBuilder object with region information.
    RegionInfo  ri = new RegionInfo("US");
    cib1.LoadDataFromRegionInfo(ri);

// Display a property of the new custom culture.
    Console.Clear();
    Console.WriteLine(msg1, cib1.CultureName);

// Save the new CultureAndRegionInfoBuilder object in the specified file in
// LDML format. The file is saved in the same directory as the application
// that calls the Save method.

    Console.WriteLine("Saving the custom culture to a file...");
    try {
        cib1.Save( savedCARIB );
        }
    catch (IOException exc)
        {
        Console.WriteLine("** I/O exception: {0}", exc.Message);
        return;
        }

// Create a new CultureAndRegionInfoBuilder object from the persisted file.
    Console.WriteLine(msg2, savedCARIB);
    try {
        cib2 = CultureAndRegionInfoBuilder.CreateFromLdml( savedCARIB );
        }
    catch (XmlException xe)
        {
        Console.WriteLine("** XML validation exception: {0}", xe.Message);
        return;
        }

// Display a property of the resonstituted custom culture.
    Console.WriteLine(msg3, cib2.CultureName);

// At this point you could call the Register method and make the reconstituted
// custom culture available to other applications. The mySavedCARIB.xml file
// remains on your computer.
    }
}

注解

参数 xmlFileName 指定包含 对象的 XML 表示形式的 CultureAndRegionInfoBuilder 文件名。 XML 文件的格式称为区域设置数据标记语言 (LDML) 版本 1.1。 将创建一个新 CultureAndRegionInfoBuilder 对象,并使用 中的数据 xmlFileName进行初始化。 方法 Save 执行 方法的 CreateFromLdml 反向操作。

在 LDML 文件中,区域性的属性指定为 节中 <identity> 元素的<special>子元素。 属性值通常由元素的 type 属性指定。 例如,LDML 文件中的以下摘录将区域性的父级定义为英语中性区域性。

<identity>
   <version number="1.1">ldml version 1.1</version>
   <generation date="2012-05-16" />
   <special xmlns:msLocale="http://schemas.microsoft.com/globalization/2004/08/carib/ldml">
      <!-content removed -->
      <msLocale:parentName type="en" />
      <!-content removed -->
   </special>
</identity>
