C#代码性能测试类（简单实用）

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
 
}
);
