1 public static void SubTest() 2 { 3 DateTime beforeDT = System.DateTime.Now; 4 int[] a = new int[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 }; 5 //Shuffle(a) is the function you want to test. 6 Shuffle(a); 7 DateTime afterDT = System.DateTime.Now; 8 TimeSpan ts = afterDT.Subtract(beforeDT); 9 Console.WriteLine("DateTime costed for Shuffle function is: {0}ms",ts.TotalMilliseconds); 10 }
第二种用Stopwatch类(System.Diagnostics)
1 public static void SubTest() 2 { 3 Stopwatch sw = new Stopwatch(); 4 sw.Start(); 5 //Shuffle(a) is the function you want to test. 6 int[] a = new int[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 }; 7 Shuffle(a); 8 sw.Stop(); 9 TimeSpan ts = sw.Elapsed; 10 Console.WriteLine("DateTime costed for Shuffle function is: {0}ms", ts.TotalMilliseconds); 11 }
1 [System.Runtime.InteropServices.DllImport("Kernel32.dll")] 2 static extern bool QueryPerformanceCounter(ref long count); 3 [System.Runtime.InteropServices.DllImport("Kernel32.dll")] 4 static extern bool QueryPerformanceFrequency(ref long count); 5 public static void SubTest() 6 { 7 long count = 0; 8 long count1 = 0; 9 long freq = 0; 10 double result = 0; 11 QueryPerformanceFrequency(ref freq); 12 QueryPerformanceCounter(ref count); 13 //Shuffle(a) is the function you want to test. 14 int[] a = new int[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 }; 15 Shuffle(a); 16 QueryPerformanceCounter(ref count1); 17 count = count1 - count; 18 result = (double)(count) / (double)freq; 19 //Note:The result is counted by second. 20 Console.WriteLine("DateTime costed for Shuffle function is: {0} s", result); 21 }
