ManualResetEvent和AutoResetEvent

  
    

   
      //
   
     ManualResetEvent reset=new ManualResetEvent(false);
   
     

   
      AutoResetEvent reset 
   
     =
   
      
   
     new
   
      AutoResetEvent(
   
     false
   
     );
 ThreadPool.QueueUserWorkItem((WaitCallback) 
   
     delegate
   
     
 {
 Console.WriteLine(
   
     "
   
     Thread 1 wait one..
   
     "
   
     );
 reset.WaitOne();
 Console.WriteLine(
   
     "
   
     Thread 1 got
   
     "
   
     );
 });

 ThreadPool.QueueUserWorkItem((WaitCallback)
   
     delegate
   
     
 {
 Console.WriteLine(
   
     "
   
     Thread 2 wait one..
   
     "
   
     );
 reset.WaitOne();
 Console.WriteLine(
   
     "
   
     Thread 2 got
   
     "
   
     );
 });
 ThreadPool.QueueUserWorkItem((WaitCallback)
   
     delegate
   
     
 {
 Console.WriteLine(
   
     "
   
     Thread 3 wait one..
   
     "
   
     );
 reset.WaitOne();
 Console.WriteLine(
   
     "
   
     Thread 3 got
   
     "
   
     );
 });
 Console.ReadLine();
 reset.Set();
 Console.WriteLine(
   
     "
   
     ok
   
     "
   
     );
  
    

二者区别在于：AutoResetEvent 会在获取到控制权时自动设置事件为非终止状态。常用于多线程中独占资源，类似lock
