Question

socket接收数据一定要写在一个死循环里吗

Answer 1

将接收数据的过程交给其他线程处理，或者使用如 clawclaw(唏嘘的胡渣)  提供的异步接收方式。不使用while死循环！

参考：

private System.Threading.ManualResetEvent receiveEvent = new System.Threading.ManualResetEvent(false); 
  
         private void ReceiveData() 
         { 
             while (true) 
             { 
                 receiveEvent.Reset(); 
                 if (m_Socket != null && m_Socket.Connected) 
                 { 
                     StateObject stateObject = new StateObject(); 
                     stateObject.workSocket = m_Socket; 
                     NetworkStream stream = new NetworkStream(m_Socket); 
                     try 
                     { 
                         stream.BeginRead(stateObject.buffer, 0, MaxBuffer, new AsyncCallback(ReceiveData), stateObject); 
  
                     } 
                     catch 
                     { 
                     } 
                 } 
                 receiveEvent.WaitOne(); 
             } 
         } 
  
         private void ReceiveData(IAsyncResult ar) 
         { 
             receiveEvent.Set(); 
         }
