C# Stopwatch的用法

Stopwatch函數,猜測可能是用來計算一個函數的運作所需時間的.代碼如下:

Stopwatch wat = new Stopwatch();
        wat.Start();

        for (int i = 1; i < 100000; i++)
        {
            res1 = str.isNumberic1();
        }
        wat.Stop();
        Console.WriteLine("isDigit      {0}:{1},{2}", str, wat.ElapsedMilliseconds, res1);

        wat.Reset();
        wat.Start();
        for (int i = 1; i < 100000; i++)
        {
            res2= str.isNumberic2();
        }
        wat.Stop();
        Console.WriteLine("isNumberic   {0}:{1},{2}", str, wat.ElapsedMilliseconds, res2);
           

wat.ElapsedMilliseconds傳回值就是在wat.Start()和wat.Stop()之間函數運作的時間
