Gets the day of the week represented by this instance.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public ReadOnly Property DayOfWeek As DayOfWeek

Property Value

Type: System.DayOfWeek
An enumerated constant that indicates the day of the week of this DateTime value.

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.

The following example demonstrates the DayOfWeek property and the System.DayOfWeek enumeration.


' This example demonstrates the DateTime.DayOfWeek property

Class Example
   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      ' Create a DateTime for the first of May, 2003.
      Dim dt As New DateTime(2003, 5, 1)
      outputBlock.Text &= String.Format("Is Thursday the day of the week for {0:d}?: {1}", _
                         dt, dt.DayOfWeek = DayOfWeek.Thursday) & vbCrLf
      outputBlock.Text &= String.Format("The day of the week for {0:d} is {1}.", dt, dt.DayOfWeek) & vbCrLf
   End Sub 'Main
End Class 'Sample

'This example produces the following results:
'
'Is Thursday the day of the week for 5/1/2003?: True
