如何使用C＃中的秒錶計算執行實際時間？

Question

我嘗試的方法中下面的代碼：

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

我計算時間在手動output window。

如何使用stopwatch（開始/重置/停止）來獲得正確的執行時間？

Answer 1

通過Stopwatch.StartNew創建的Stopwatch一個實例，執行你的方法。停止Stopwatch然後得到ElapsedMilliseconds像：

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

請記住，包括using System.Diagnostics;

Answer 2

使用Stopwatch類：

// 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

按照MSDN：

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