vb.net验证所选日期字段中的天数

Question

I have two textboxes which are date pickers. tbStartDate and tbEndDate . The user should only pick a date that starts on a Monday and ends on a Friday, eg

tbStart.text = 05/11/2012 (Mon 5th November 2012)
tbEndDate.text = 09/11/2012 (Fri 11th November 2012)

I need to validate that the start and end dates are Monday and Friday respectively.

I am using asp.net (Visual Basic). What is the best solution to my problem? Thanks

RESOLVED:

Sub GetDayOfWeek()
Dim MyDate As Date = "2012/11/04"
        If MyDate.DayOfWeek.ToString() = "Sunday" Then
            Response.Write("Cannot be a weekend!")
         Else
            Response.Write("Weekday Detected!")
        End If
    End Sub
