DateAndTime.WeekdayName Method

Silverlight

Returns a String value containing the name of the specified weekday.

Namespace: Microsoft.VisualBasic
Assembly: Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

public static string WeekdayName(
	int Weekday,
	bool Abbreviate,
	FirstDayOfWeek FirstDayOfWeekValue
)

Parameters

Weekday: Type: System.Int32
Required. Integer. The numeric designation for the weekday, from 1 through 7; 1 indicates the first day of the week and 7 indicates the last day of the week. The identities of the first and last days depend on the setting of FirstDayOfWeekValue.

Abbreviate: Type: System.Boolean
Optional. Boolean value that indicates if the weekday name is to be abbreviated. If omitted, the default is False, which means the weekday name is not abbreviated.

FirstDayOfWeekValue: Type: Microsoft.VisualBasic.FirstDayOfWeek
Optional. A value chosen from the FirstDayOfWeek enumeration that specifies the first day of the week. If not specified, FirstDayOfWeek.System is used.

Return Value

Type: System.String
Returns a String value containing the name of the specified weekday.

Remarks

The string returned by WeekdayName depends not only on the input arguments, but also on the Regional Options settings specified in the Windows Control Panel.

Note:
WeekdayName uses the current calendar setting from the CurrentCulture property of the CultureInfo class in the System.Globalization namespace. The default CurrentCulture values are determined by Control Panel settings.

The FirstDayOfWeekValue argument can have one of the following settings.

Enumeration value	Value	Description
FirstDayOfWeek.System	0	First day of week specified in system settings (default)
FirstDayOfWeek.Sunday	1	Sunday
FirstDayOfWeek.Monday	2	Monday (complies with ISO standard 8601, section 3.17)
FirstDayOfWeek.Tuesday	3	Tuesday
FirstDayOfWeek.Wednesday	4	Wednesday
FirstDayOfWeek.Thursday	5	Thursday
FirstDayOfWeek.Friday	6	Friday
FirstDayOfWeek.Saturday	7	Saturday

Examples

The following example uses the Weekday function to obtain the day of the week from a specified date, and then the WeekDayName function to obtain the name of the weekday from its number.


Dim oldDate As Date
Dim oldWeekDayName As String
oldDate = #2/12/1969#
oldWeekDayName = WeekdayName(Weekday(oldDate))
' oldWeekDayName now contains "Wednesday".
