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.
