Question

我需要计算系统运行的持续时间.我在c#中的系统.我已经设定:

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

经过几个过程.

我设置 :

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

要准确测量经过的时间,请使用StopWatch类:

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);
