how to cal minutes difference between two timings

              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?..

thanks vimal,

i wrote datedifference formula in crystalreports like this

datediff("n",{GeofenceDetails.EntryTime},{GeofenceDetails.ExitTime})

for some two timings difference i get negative values

i want to dispaly only +ve values for my report output

pls give me any solution ...

            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.
