I need to calculate duration for my system running. My system in c#.
I’ve set:

DateTime startRunningProg = Date.Time.Now("o");

after a few process.

I set :

DateTime endRunningProg = Date.Time.Now("o");

How to calculate duration for my system running in millisec or sec.

Answer 1

to accurately measure elapsed time, use StopWatch class:

Stopwatch stopWatch = new Stopwatch();
stopWatch.Start();
Thread.Sleep(10000);
stopWatch.Stop();
// Get the elapsed time as a TimeSpan value.
TimeSpan ts = stopWatch.Elapsed;

// Format and display the TimeSpan value.
string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",
    ts.Hours, ts.Minutes, ts.Seconds,
    ts.Milliseconds / 10);
Console.WriteLine("RunTime " + elapsedTime);
