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
  
}
);
