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 }
);
