DateTime::DayOfWeek Property
Gets the day of the week represented by this instance.
Assembly: mscorlib (in mscorlib.dll)
The value of the constants in the DayOfWeek enumeration ranges from DayOfWeek::Sunday to DayOfWeek::Saturday. If cast to an integer, its value ranges from zero (which indicates DayOfWeek::Sunday) to six (which indicates DayOfWeek::Saturday).
The DayOfWeek property returns an enumerated constant; it does not reflect a system's regional and language settings. 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. For details, see How to: Extract the Day of the Week from a Specific Date.
The following example demonstrates the DayOfWeek property and the System::DayOfWeek enumeration.
// 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. */
