C#代码性能测试类（简单实用）

PerformanceTest p = new PerformanceTest();p.SetCount(10);//循环次数(默认:1)p.SetIsMultithread(true);//是否启动多线程测试 (默认:false)p.Execute(i =>{  //需要测试的代码  Response.Write(i+"<br>");  System.Threading.Thread.Sleep(1000);  },message =>{   //输出总共运行时间  Response.Write(message);  //总共执行时间：1.02206秒 });
