c#计算程序执行时间 计算一段代码执行所用的时间 测试效率

有了下面这个c#计算程序执行时间,计算一段代码执行所用的时间,测试效率教程，不懂c#计算程序执行时间,计算一段代码执行所用的时间,测试效率的也能装懂了，赶紧get起来装逼一下吧！

using System; using ; class Class1 { [System.Runtime.InteropServices.DllImport("Kernel32.dll")] staticexternbool QueryPerformanceCounter(reflong count); [System.Runtime.InteropServices.DllImport("Kernel32.dll")] staticexternbool QueryPerformanceFrequency(reflong count); [STAThread] staticvoid Main(string[] args) { long count = 0; long count1 = 0; long freq = 0; double result = 0; QueryPerformanceFrequency(ref freq); QueryPerformanceCounter(ref count); //需要测试的模块 int heisetoufa; for (heisetoufa = 1; heisetoufa 10000; heisetoufa++) {Console.WriteLine("第" + heisetoufa + "行");if (heisetoufa == 5000){Thread.Sleep(10000);} }//需要测试的模块QueryPerformanceCounter(ref count1); count = count1 - count; result = (double)(count) / (double)freq; Console.WriteLine("耗时: {0} 秒", result); Console.ReadLine(); } }
