lblgetdate.Text = dt.ToLongDateString();
DateTime sDate = new DateTime();
sDate = Calendar.SelectedDate;
DateTime eDate = new DateTime();
eDate = Convert.ToDateTime(lblgetdate.Text);
DayOfWeek fWeek = DayOfWeek.Friday;

Solution 1

You can do that. However, which component of the DateTime do you want to subtract this integer from e.g. year / day / second and so on.

Basically, use the TimeSpan class to do the difference.
Use the FromDays, FromHours method or whichever one that you need to do the difference.
See here[^].

Solution 2

try this

VB

Dim dt As New Date
dt = "26-12-2011"
Dim a As Integer = 6
Dim a1 As Integer = 1

 While a1 <= Len(dt)
   If a = Mid(dt, a1, 1) Then
      MsgBox(a)
      Exit While
   End If
   a1 = a1 + 1
 End While
