介绍：

可以很方便的在代码里循环执行 需要测试的函数 自动统计出执行时间，支持多线程。

使用方法：

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 } );
