Beispiele

// This example demonstrates the DateTime.DayOfWeek property
using namespace System;
int main()
{
   
   // Assume the current culture is en-US.
   // Create a DateTime for the first of May, 2003.
   DateTime dt = DateTime(2003,5,1);
   Console::WriteLine(  "Is Thursday the day of the week for {0:d}?: {1}", dt, dt.DayOfWeek == DayOfWeek::Thursday );
   Console::WriteLine(  "The day of the week for {0:d} is {1}.", dt, dt.DayOfWeek );
}

/*
This example produces the following results:

Is Thursday the day of the week for 5/1/2003?: True
The day of the week for 5/1/2003 is Thursday.

Hinweise

Der Wert der Konstanten in der DayOfWeek Enumeration reicht von DayOfWeek.Sunday bis DayOfWeek.Saturday.The value of the constants in the DayOfWeek enumeration ranges from DayOfWeek.Sunday to DayOfWeek.Saturday. Wenn Sie in eine ganze Zahl umgewandelt wird, reicht der Wert von 0 (null) (was DayOfWeek.Sunday) auf sechs (DayOfWeek.Saturday).If cast to an integer, its value ranges from zero (which indicates DayOfWeek.Sunday) to six (which indicates DayOfWeek.Saturday).

Die DayOfWeek-Eigenschaft gibt eine Enumerationskonstante zurück. Es spiegelt nicht die Regions-und Spracheinstellungen eines Systems wider.The DayOfWeek property returns an enumerated constant; it does not reflect a system's regional and language settings. Um eine Zeichenfolge abzurufen, die einen lokalisierten Wochentagsnamen für ein bestimmtes Datum darstellt, rufen Sie eine der über Ladungen der ToString Methode auf, die einen format-Parameter enthält, und übergeben Sie entweder die ddd oder dddd benutzerdefinierte Format Zeichenfolgen.To retrieve a string representing a localized weekday name for a particular date, call one of the overloads of the ToString method that includes a format parameter and pass it either the ddd or dddd custom format strings. Weitere Informationen finden Sie unter Gewusst wie: Extrahieren des Wochentags aus einem bestimmten Datum.For details, see How to: Extract the Day of the Week from a Specific Date.
