属性

示例

下面的代码示例演示DateTimeFormatInfo了在纪元名称中忽略标点, 仅当日历为公历并且区域性使用纪元名称 "公元" 时。The following code example shows that DateTimeFormatInfo ignores the punctuation in the era name, only if the calendar is Gregorian and the culture uses the era name "A.D.".

using namespace System;
using namespace System::Globalization;
using namespace System::Collections;
int main()
{
   
   // Creates strings with punctuation and without.
   String^ strADPunc = "A.D.";
   String^ strADNoPunc = "AD";
   String^ strCEPunc = "C.E.";
   String^ strCENoPunc = "CE";
   
   // Calls DTFI::GetEra for each culture that uses GregorianCalendar as the default calendar.
   Console::WriteLine( "            ----- AD -----  ----- CE -----" );
   Console::WriteLine( "CULTURE     PUNC   NO PUNC  PUNC   NO PUNC  CALENDAR" );
   IEnumerator^ en = CultureInfo::GetCultures( CultureTypes::SpecificCultures )->GetEnumerator();
   while ( en->MoveNext() )
   {
      CultureInfo^ myCI = safe_cast<CultureInfo^>(en->Current);
      Console::Write( "{0, -12}", myCI );
      Console::Write( "{0,-7}{1,-9}", myCI->DateTimeFormat->GetEra( strADPunc ), myCI->DateTimeFormat->GetEra( strADNoPunc ) );
      Console::Write( "{0, -7}{1, -9}", myCI->DateTimeFormat->GetEra( strCEPunc ), myCI->DateTimeFormat->GetEra( strCENoPunc ) );
      Console::Write( "{0}", myCI->Calendar );
      Console::WriteLine();
   }
}

注解

公历可识别两个纪元:B.C.The Gregorian calendar recognizes two eras: B.C. 或 B.C.E., 以及公元or B.C.E., and A.D. 或公历or C.E. GregorianCalendar类实现仅识别当前时代 (公元This implementation of the GregorianCalendar class recognizes only the current era (A.D. 或公历)。or C.E.).

备注

有关使用 .NET Framework 中的GregorianCalendar类和其他 calendar 类的信息, 请参阅使用日历For information about using the GregorianCalendar class and the other calendar classes in the .NET Framework, see Working with Calendars.

公历中的闰年定义为一个年份, 该年份可被4整除, 除非100可被。A leap year in the Gregorian calendar is defined as a year that is evenly divisible by 4, unless it is divisible by 100. 但是, 400 可以整除的年份是闰年。However, years that are divisible by 400 are leap years. 例如, 1900 年不是闰年, 而2000是。For example, the year 1900 was not a leap year, but the year 2000 was. 一个常见年份有365天, 闰年有366天。A common year has 365 days and a leap year has 366 days.

公历包含12个月, 每个月28到31天:1月 (31 天), 二月 (28 或29天), 三月 (31 天), 4 月 (30 天), 5 月 (31 天), 6 月 (30 天), 7 月 (31 天), 8 月 (31 天), 11 月 (30 天), 12 月 (31 天)。The Gregorian calendar has 12 months with 28 to 31 days each: January (31 days), February (28 or 29 days), March (31 days), April (30 days), May (31 days), June (30 days), July (31 days), August (31 days), September (30 days), October (31 days), November (30 days), and December (31 days). 2月在闰年中有29天, 在常见年份内有28天。February has 29 days during leap years and 28 during common years.

重要

默认情况下, DateTime所有DateTimeOffset和值均以公历表示日期和时间。By default, all DateTime and DateTimeOffset values express dates and times in the Gregorian calendar.

公历是作为儒略历 (由JulianCalendar类表示) 的替代, 最初在1582年10月15日在少数文化中引入。The Gregorian calendar was developed as a replacement for the Julian calendar (which is represented by the JulianCalendar class) and was first introduced in a small number of cultures on October 15, 1582. 当使用在某个区域性采用公历日历之前的历史日期时, 如果该日历在 .NET Framework 中可用, 则应使用原始日历。When working with historic dates that precede a culture's adoption of the Gregorian calendar, you should use the original calendar if it is available in the .NET Framework. 例如, 丹麦将儒略历从儒略历改为1700年2月19日 (公历日历) 或3月1日 (公历日历)。For example, Denmark changed from the Julian calendar to the Gregorian calendar on February 19 (in the Julian calendar) or March 1 (in the Gregorian calendar) of 1700. 在这种情况下, 对于采用公历之前的日期, 应使用 Julian 日历。In this case, for dates before the adoption of the Gregorian calendar, you should use the Julian calendar. 但请注意, 任何区域性都不提供对类JulianCalendar的内部支持。However, note that no culture offers intrinsic support for the JulianCalendar class. 必须使用JulianCalendar类作为独立日历。You must use the JulianCalendar class as a standalone calendar. 有关详细信息, 请参阅使用日历For more information, see Working with calendars.

下面的示例说明了儒略历1700年2月18日 (即丹麦的 Julian 日历的最后一天), 该日历是公历中早于1700的一天。The following example illustrates that February 18, 1700 in the Julian calendar, which is the last day the Julian calendar was officially used in Denmark, is one day earlier than March 1, 1700 in the Gregorian calendar.

CultureInfo个都支持一组日历。Each CultureInfo supports a set of calendars. 属性返回区域性的默认日历, OptionalCalendars属性返回一个数组, 该数组包含该区域性支持的所有日历。 CalendarThe Calendar property returns the default calendar for the culture, and the OptionalCalendars property returns an array containing all the calendars supported by the culture. 若要更改使用CultureInfo的日历, 应用程序可以Calendar将属性设置为新Calendar的。To change the calendar used by a CultureInfo, the application can set the Calendar property to a new Calendar.

GetEra仅当GregorianCalendar在中DateTimeFormatInfo.Calendar选择了并且区域性使用 "公元" 时, 才会忽略缩写名称中的标点符号GetEra ignores punctuation in abbreviated era names, only if the GregorianCalendar is selected in DateTimeFormatInfo.Calendar and the culture uses "A.D." 作为纪元名称, 即 "公元"as the era name, that is, "A.D." 等效于 "AD"。is equivalent to "AD".
