Date Comparison in C# with millisecond

            DateTime dt1 = Convert.ToDateTime("04/17/2014 04:05:25.8652258 AM");
            DateTime dt2 = Convert.ToDateTime("04/17/2014 04:05:25.8652258 PM");
            int Res = DateTime.Compare(dt1, dt2);//args[0] is latest time, args[1] is old time
            
If Res returns 0(zero) then both values are equal.
If Res returns -1 then dt2 is the latest time
If Res returns 1 then the condition is true. dt1 is latest.
