Dot Net (C#): Dauer ermitteln mit Stopwatch

Die Klasse Stopwatch aus dem Namespace System.Diagnostics ermöglicht es, Zeiten genau zu stoppen:

Stopwatch sw = new Stopwatch();
sw.Start();
/* do your work */
sw.Stop();
this.labelTime.Text =
    "ElapsedTicks: " + sw.ElapsedTicks.ToString() +
    "\nElapsedMilliseconds :" + sw.ElapsedMilliseconds.ToString() +
    "\nElapsed(TimeSpan) :" + sw.Elapsed.ToString();
