If string to DateTime conversion is yur problem then u can use, Convert.ToDateTime("10/02/2009 03:37:25") to make a DateTime object of your string. Alternately, DateTime.Parse. For comparing, http://www.codeproject.com/script/Forums/View.aspx?fid=12076&select=2917783&fr=1#xx2917783xx[^]

        DateTime Dt= DateTime.Parse("10/02/2009 03:37:25");
        DateTime Dt2 = DateTime.Parse("10/02/2009 14:30:00");
        TimeSpan t = Dt.Subtract(Dt2);
        MessageBox.Show(t.TotalHours.ToString());

Now From Time Span you can get the time Difference ;)

It looks like the date OP is talking about is in dd/mm/yyyy format. If yes, your code will fail. It will take 02 as date and 10 as month. You need to use DateTime.ParseExact with an invariant culture and required format. :)
