Solution 1

This is simple math. Total time is always EndTime - StartTime.

If you subtrace one datetime value from another then result is a TimeSpan object with the "total time" as you call it.

Solution 2

Assuming the starttime and end times are both of type DateTime:

C#

TimeSpan span = endTime - StartTime;

At this point, you can use the properties in the TimeSpan object to determine the amount of time.

Solution 3

Try:

C#

DateTime start = new DateTime(1, 1, 1, 7, 0, 0);
DateTime end = new DateTime(1, 1, 1, 10, 0, 0);
TimeSpan ts = end - start;
int diffHours = ts.Hours;
