Thread: Best way for duration - time pasted

Look at using TimeSpan.

DateTime prev = DateTime.Now; ... // some time later ... TimeSpan diff = DateTime.Now - prev;

Use a TimeSpan: Code: DateTime start = DateTime.Now; ... DateTime end = DateTime.Now; TimeSpan span = end - start; EDIT: ninja'd

thanks all of you, thanks

Code: TimeSpan diff = DateTime.Now - DateTime.Parse(chargedataGridView.Rows[oRow.Index] .Cells[1].Value.ToString()) ; TimeSpan duration = new TimeSpan(diff.Hours, diff.Minutes, diff.Seconds); chargedataGridView.Rows[oRow.Index] .Cells[1].Value = duration.ToString(); i have this, it doesn't works if the first event is 23:00:00 and the second 1:00:00 and because i have it on a timer it ...

There is also Stopwatch class.

"DateTime.Parse(chargedataGridView.Rows[oRow.Index ].Cells[1].Value.ToString()) " And what value do you expect that to give you? Did you check the output of that function call?

pfff my bad i understand what you mean about what it gives me... you are right.. ill solve it now thanks..
