Valor de propiedad

Calendario que se usará para la referencia cultural actual. El valor predeterminado de InvariantInfo es un objeto GregorianCalendar.

Excepciones

Ejemplos

En el ejemplo siguiente se define un ChangeCalendar método que cambia el calendario actual de una referencia cultural a un calendario especificado, a menos que ya sea el calendario actual o si no es compatible con la referencia cultural. El código que llama al método crea una instancia de un CultureInfo objeto que representa la referencia cultural árabe (Egipto) y primero intenta cambiar su calendario al calendario japonés. Dado que no se admite el calendario japonés, el método no cambia el calendario de la referencia cultural. Sin embargo, dado que el calendario um al-Qura es miembro de la CultureInfo.OptionalCalendars colección, el método tiene éxito para convertirlo en el calendario actual para la referencia cultural ar-EG.

Comentarios

La Calendar propiedad solo acepta calendarios que son válidos para la referencia cultural asociada al DateTimeFormatInfo objeto . La CultureInfo.OptionalCalendars propiedad especifica los calendarios que puede usar una referencia cultural determinada y la CultureInfo.Calendar propiedad especifica el calendario predeterminado para la referencia cultural.

Cambiar el valor de esta propiedad también afecta a las siguientes propiedades: MonthNames, AbbreviatedMonthNames, DayNames, AbbreviatedDayNames, CalendarWeekRule, FirstDayOfWeekFullDateTimePatternShortDatePatternLongDatePattern, , YearMonthPatterny .MonthDayPattern

Por ejemplo, si la referencia cultural del subproceso actual es japonesa, esta propiedad acepta JapaneseCalendar, LocalizedGregorianCalendaro USEnglishGregorianCalendar. JapaneseCalendar Cuando se usa , el especificador de fecha larga predeterminado es "gg y'\x5e74'M'\x6708'd'\x65e5'". LocalizedGregorianCalendarCuando se usa , el especificador de fecha larga predeterminado es "aaaa"\x5e74'M'\x6708'd'\x65e5'".
