Beispiele

Das folgende Beispiel zeigt, wie das Ergebnis der GetWeekOfYear Methode abhängig von den FirstDayOfWeek verwendeten Werten und CalendarWeekRule variiert. Wenn das angegebene Datum der letzte Tag des Jahres ist, GetWeekOfYear gibt die Gesamtzahl der Wochen in diesem Jahr zurück.

using namespace System::Globalization;
int main()
{
   
   // Gets the Calendar instance associated with a CultureInfo.
   CultureInfo^ myCI = gcnew CultureInfo( "en-US" );
   Calendar^ myCal = myCI->Calendar;
   
   // Gets the DTFI properties required by GetWeekOfYear.
   CalendarWeekRule myCWR = myCI->DateTimeFormat->CalendarWeekRule;
   DayOfWeek myFirstDOW = myCI->DateTimeFormat->FirstDayOfWeek;
   
   // Displays the number of the current week relative to the beginning of the year.
   Console::WriteLine( "The CalendarWeekRule used for the en-US culture is {0}.", myCWR );
   Console::WriteLine( "The FirstDayOfWeek used for the en-US culture is {0}.", myFirstDOW );
   Console::WriteLine( "Therefore, the current week is Week {0} of the current year.", myCal->GetWeekOfYear( DateTime::Now, myCWR, myFirstDOW ) );
   
   // Displays the total number of weeks in the current year.
   DateTime LastDay = System::DateTime( DateTime::Now.Year, 12, 31 );
   Console::WriteLine( "There are {0} weeks in the current year ( {1}).", myCal->GetWeekOfYear( LastDay, myCWR, myFirstDOW ), LastDay.Year );

This code produces the following output.  Results vary depending on the system date.

The CalendarWeekRule used for the en-US culture is FirstDay.

Hinweise

Diese Methode kann verwendet werden, um die Anzahl der Wochen im Jahr zu bestimmen, indem der time Parameter auf den letzten Tag des Jahres festgelegt wird.

CultureInfo.DateTimeFormat enthält kulturspezifische Werte, die für die rule Parameter und firstDayOfWeek verwendet werden können.

Die FirstDayOfWeek -Eigenschaft von CultureInfo.DateTimeFormat enthält den Standardwert DayOfWeek , der den ersten Tag der Woche für eine bestimmte Kultur darstellt, wobei der in der Calendar -Eigenschaft von CultureInfo.DateTimeFormatangegebene Kalender verwendet wird.

Die CalendarWeekRule -Eigenschaft von CultureInfo.DateTimeFormat enthält den Standardwert CalendarWeekRule , der eine Kalenderwoche für eine bestimmte Kultur definiert, wobei der in der Calendar -Eigenschaft von CultureInfo.DateTimeFormatangegebene Kalender verwendet wird.

Beispielsweise gibt in GregorianCalendarfür GetWeekOfYear Januar 1 1 zurück.
