try this DateTime t1 = DateTime.Parse(2008-09-10 23:23:53.077); DateTime t2 = DateTime.Parse(2008-08-10 14:33:19.140); TimeSpan td = t1.Subtract(t2); MessageBox.Show(td.Duration().Days.ToString()); The above code will retrieve no of days between given dates. i have one doubt.Exit time will be greater than entry time na?... then how negative values will come?..

i think you need time difference between two timings.try this... DateTime t1 = DateTime.Parse(2008-09-10 23:23:53.077); DateTime t2 = DateTime.Parse(2008-09-10 14:33:19.140); TimeSpan td = t2.Subtract(t1); MessageBox.Show(td.Duration().ToString()); because if you find only minutes difference.there may be chance for negative values.
