示例

下面的代码示例演示如何确定区域性支持GregorianCalendar的版本。The following code example demonstrates how to determine the GregorianCalendar versions supported by the culture.

using namespace System;
using namespace System::Globalization;
using namespace System::Collections;
int main()
{
   
   // Calendar* myOptCals[] = new CultureInfo(S"ar-SA") -> OptionalCalendars;
   CultureInfo^ MyCI = gcnew CultureInfo( "ar-SA" );
   array<Calendar^>^myOptCals = MyCI->OptionalCalendars;
   
   // Checks which ones are GregorianCalendar then determines the GregorianCalendar version.
   Console::WriteLine( "The ar-SA culture supports the following calendars:" );
   IEnumerator^ myEnum = myOptCals->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Calendar^ cal = safe_cast<Calendar^>(myEnum->Current);
      if ( cal->GetType() == GregorianCalendar::typeid )
      {
         GregorianCalendar^ myGreCal = dynamic_cast<GregorianCalendar^>(cal);
         GregorianCalendarTypes calType = myGreCal->CalendarType;
         Console::WriteLine( " {0} ( {1})", cal, calType );
      }
      else
            Console::WriteLine( " {0}", cal );
   }
}

/*

The ar-SA culture supports the following calendars:
 System.Globalization.HijriCalendar
 System.Globalization.GregorianCalendar ( USEnglish)
 System.Globalization.GregorianCalendar ( MiddleEastFrench)
 System.Globalization.GregorianCalendar ( Arabic)

注解

应用CultureInfo程序通过Calendar设置的属性DateTimeFormatDateTimeFormatInfo类的实例)更改当前使用的日历。Your application changes the calendar used by the current CultureInfo by setting the Calendar property of DateTimeFormat, which is an instance of the DateTimeFormatInfo class. 新日历必须是中OptionalCalendars列出的其中一个日历。The new calendar must be one of the calendars listed in OptionalCalendars. DateTimeFormat还包括一些自定义与该Calendar关联的日期和时间格式设置的属性。DateTimeFormat also includes other properties that customize the date and time formatting associated with that Calendar.
