据我所知,我可以同时使用 TCPListener 和 Socket 创建服务器,那么它们两者有什么区别?
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());
TCP监听器
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。他们两个监听连接,那么他们之间有什么区别?
