Socket的监听的三种方式

首先要打开监听

1 2 3 4

Listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP); IPEndPoint hostEntry = new IPEndPoint(getLocalmachineIPAddress(), ServerPort); Listener.Bind(hostEntry); Listener.Listen(ConnectionsQueueLength);

　　

1. AcceptAsync异步方式

1 2 3 4 5

socketEventArg = new SocketAsyncEventArgs(); socketEventArg.Completed += new EventHandler<SocketAsyncEventArgs>(SocketEventArg_Completed); socketEventArg.RemoteEndPoint = hostEntry; socketEventArg.UserToken = Listener; Listener.AcceptAsync(socketEventArg);

　　

void SocketEventArg_Completed(object sender, SocketAsyncEventArgs e) {     if (e.LastOperation == SocketAsyncOperation.Accept)     {         Socket acceptSocket = e.AcceptSocket;           if (acceptSocket != null)         {              // 处理方法         }     }       e.AcceptSocket = null;     Listener.AcceptAsync(e);   }

　　

 

2. Accept方式 

1 2 3 4 5 6 7

while (true) {     Socket acceptSocket = Listener.Accept();       if (acceptSocket != null)     {         // 处理代码

1 2

} }

　　

 3. BeginAccept方式

1 2 3 4

while (true) {     Listener.BeginAccept(new AsyncCallback(AcceptCallBack), Listener); }

private void AcceptCallBack(IAsyncResult result) {     Socket acceptSocket = (Socket)result.AsyncState;     // 处理方法 }
