套接字 – TCP侦听器和套接字之间的区别

据我所知,我可以使用TCPListener和Socket创建一个服务器,所以两者之间有什么区别?

插座

private Socket MainSock;
MainSock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
MainSock.Bind(new IPEndPoint(IPAddress.Any, port));
MainSock.Listen(500);
MainSock.BeginAccept(AcceptConnections, new Wrapper());

的TCPListener

    Int32 port = 13000;
    IPAddress localAddr = IPAddress.Parse("127.0.0.1");
    TcpListener server = new TcpListener(localAddr, port);
    server.Start();

我真的很困惑他们两个听连接,那么他们之间有什么区别呢?

最佳答案
他们只是不同的类,做同样的事情,写在不同的层次。在引擎盖下,TCPListener无疑地称之为第一个基于Socket的代码。它只是在那里隐藏你的一些血腥的细节。
