CultureInfo.OptionalCalendars 屬性

定義

取得可為文化特性所使用的曆法清單。Gets the list of calendars that can be used by the culture.

public:
 virtual property cli::array <System::Globalization::Calendar ^> ^ OptionalCalendars { cli::array <System::Globalization::Calendar ^> ^ get(); };
public virtual System.Globalization.Calendar[] OptionalCalendars { get; }
member this.OptionalCalendars : System.Globalization.Calendar[]
Public Overridable ReadOnly Property OptionalCalendars As Calendar()

屬性值

Calendar 類型的陣列,代表可為目前 CultureInfo 所代表之文化特性所使用的曆法。An array of type Calendar that represents the calendars that can be used by the culture represented by the current CultureInfo.

範例

下列程式碼範例示範如何判斷文化特性所支援的 GregorianCalendar 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 );
   }
}

/*
This code produces the following output.

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

備註

您的應用程式會藉由設定 DateTimeFormatCalendar 屬性(也就是 DateTimeFormatInfo 類別的實例),來變更目前 CultureInfo 所使用的行事曆。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. 新行事曆必須是 OptionalCalendars中所列的其中一個行事曆。The new calendar must be one of the calendars listed in OptionalCalendars. DateTimeFormat 也包含可自訂與該 Calendar相關聯之日期和時間格式的其他屬性。DateTimeFormat also includes other properties that customize the date and time formatting associated with that Calendar.
