   // Create an instance of the calendar.
   JapaneseCalendar^ myCal = gcnew JapaneseCalendar;
   Console::WriteLine( myCal );
   
   // Create an instance of the GregorianCalendar.
   GregorianCalendar^ myGre = gcnew GregorianCalendar;
   
   // Display the MinSupportedDateTime and its equivalent in the GregorianCalendar.
   DateTime myMin = myCal->MinSupportedDateTime;
   Console::Write( "MinSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal->GetMonth( myMin ), myCal->GetDayOfMonth( myMin ), myCal->GetYear( myMin ) );
   Console::WriteLine( " (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre->GetMonth( myMin ), myGre->GetDayOfMonth( myMin ), myGre->GetYear( myMin ) );
   
   // Display the MaxSupportedDateTime and its equivalent in the GregorianCalendar.
   DateTime myMax = myCal->MaxSupportedDateTime;
   Console::Write( "MaxSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal->GetMonth( myMax ), myCal->GetDayOfMonth( myMax ), myCal->GetYear( myMax ) );
   Console::WriteLine( " (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre->GetMonth( myMax ), myGre->GetDayOfMonth( myMax ), myGre->GetYear( myMax ) );

注解

该班支持的 JapaneseCalendar 最早日期是1868年9月8日，即明治时代的第一年。 通常，使用 JapaneseCalendar 类的日期和时间操作会针对此日期之前的日期引发 ArgumentOutOfRangeException 异常。 然而，一些成员，如 GetEra 方法，支持日期从 1868 年 1 月 1 日到 9 月 7 日在 1868 年 9 月 1 日。
