Question

What I mean is…

get the time, run the code, get the time, compare the time and get the seconds out:

am I doing this right?

DateTime timestamp = DateTime.Now;
//...do the code...
DateTime endstamp = DateTime.Now;

string results = ((endstamp.ticks - timestamp.ticks)/10000000).ToString();

Answer 1

No. Use the System.Diagnostics.Stopwatch class instead. DateTime.Now doesn’t have the level of precision that you desire (although the DateTime struct is plenty precise, in and of itself).

Stopwatch watch = new Stopwatch();
watch.Start();
// do stuff
watch.Stop();
long ticks = watch.ElapsedTicks;
