Question

我在方法中尝试了以下代码：

Trace.Write("START "+Datetime.now);
//DATABASE METHOD CALL 
SaveData();
Trace.Write("END "+Datetime.now);

我手动计算output window的时间。

如何使用stopwatch（启动/重置/停止）来获取正确的执行时间？

Answer 1

按Stopwatch创建Stopwatch.StartNew的实例，执行您的方法。停止Stopwatch然后获取ElapsedMilliseconds，如：

Stopwatch stopwatch = Stopwatch.StartNew();
SaveData();
stopwatch.Stop();
Trace.Write("Time in Millisecond:  " + stopwatch.ElapsedMilliseconds);

请记住加入using System.Diagnostics;

Answer 2

使用Stopwatch类：

    // Create new stopwatch
    Stopwatch stopwatch = new Stopwatch();

    // Begin timing
    stopwatch.Start();

    // Do something
    for (int i = 0; i < 1000; i++)
    {
        Thread.Sleep(1);
    }

    // Stop timing
    stopwatch.Stop();

    // Write result
    Console.WriteLine("Time elapsed: {0}",
        stopwatch.Elapsed);

Answer 3

根据msdn：

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

StopWatch

如何在c＃中使用秒表计算执行实际时间？
