问题描述

有这样一段测试代码

string[] args)

   2:  {

   3:      Action funcDelegate = TestFunc;

   4:      funcDelegate.BeginInvoke(Done, funcDelegate);

   5:      Console.ReadKey();

   6:  }

   7:  

void Done(IAsyncResult ar)

   9:  {

try

  11:      {

  12:          var funcDelegate =  (Action)ar.AsyncState;

  13:          funcDelegate.EndInvoke(ar);

catch(Exception e)

  15:      {

,e.Message);

  17:      }

  18:  }

  19:  

void TestFunc()

  21:  {

  22:      Thread.Sleep(2000);

);
