如何估计方法执行时间？ [英] How to estimate method execution time?

问题描述

我需要取消方法执行，如果它需要两秒钟以上完成和在另一个线程重新启动它。

I have requirement to cancel method execution if it takes the more than two seconds to complete and restart it on another thread.

所以，有没有任何方式/

So, is there any way/call back mechanism/HACK, I can make method inform me that it crossed 2 seconds time limit?

推荐答案

检查网络驱动器是否存在，并在c＃中设置超时

异步模式：

public static T SafeLimex<T>(Func<T> F, int Timeout, out bool Completed)   
   {
       var iar = F.BeginInvoke(null, new object());
       if (iar.AsyncWaitHandle.WaitOne(Timeout))
       {
           Completed = true;
           return F.EndInvoke(iar);
       }
         F.EndInvoke(iar); //not calling EndInvoke will result in a memory leak
         Completed = false;
       return default(T);
   }
