We have to use the TimeSpan class for this.


DateTime first = DateTime.Today;
DateTime second = DateTime.Today.AddDays(-1);

TimeSpan span = first - second;

span = span.Add(span);

double days = span.TotalDays;

hi Naresh

just convert the store string to TimeSpan.

then u can compare and get the difference...

ex: VB.net Code
Dim d As TimeSpan = CDate(string1).TimeOfDay
Dim d1 As TimeSpan = CDate(string2).TimeOfDay
Dim Minutes As Integer = (string1 - string1).TotalMinutes

now u will get the diff in Minutes...

hope above code will help u.....
