Vb.net得到了工作日的名字

Question

今天是21.10.2012.这是星期天
但我的VB.NET认为不同:

Debug.Print("Weekday for the date '21.10.2012.'is " & WeekdayName(Weekday("21.10.2012.")))
Debug.Print("Weekday for the date '21/10/2012'is " & WeekdayName(Weekday("21/10/2012")))
Debug.Print("Weekday for the date '" & DateTime.Now.Date & "'is " & WeekdayName(Weekday(DateTime.Now.Date)))

所有这3张支票都给我:工作日名称'星期一'!
如何获得合适的工作日名称？

Answer 1

这是获取给定日期的工作日名称的正确.NET方法:

Dim myCulture As System.Globalization.CultureInfo = Globalization.CultureInfo.CurrentCulture
Dim dayOfWeek As DayOfWeek = myCulture.Calendar.GetDayOfWeek(Date.Today)
' dayOfWeek.ToString() would return "Sunday" but it's an enum value,
' the correct dayname can be retrieved via DateTimeFormat.
' Following returns "Sonntag" for me since i'm in germany '
Dim dayName As String = myCulture.DateTimeFormat.GetDayName(dayOfWeek)
