性能测试类，让你写法代码养成经常测试的好习惯 -ASP.NET C#

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

            }
            );
