“无法打开套接字或拒绝连接"与.NET [英] "Can´t open socket or connection refused" with .NET

问题描述

当我尝试使用netcat将一些数据发送到服务器应用程序时，连接被拒绝.

Im getting a connection refused when I try to send some data to my server app using netcat.

服务器端:

IPAddress ip;
ip = Dns.GetHostEntry("localhost").AddressList[0];
IPEndPoint ipFinal = new IPEndPoint(ip, 12345);
Socket socket = new Socket(AddressFamily.InterNetworkV6, SocketType.Stream, ProtocolType.Tcp);
socket.Bind(ipFinal);
socket.Listen(100);
Socket handler = socket.Accept(); ------> it stops here......nothing happens

推荐答案

问题解决了，我不得不在数组中移动1个位置，导致第一个位置指向一个IPv6地址.

Problem solved, I had to move 1 position in the array, cause the first position points to an IPv6 address.

IPAddress ip;
ip = Dns.GetHostEntry("localhost").AddressList[1];
IPEndPoint ipFinal = new IPEndPoint(ip, 12345);
Socket socket = new Socket(AddressFamily.InterNetworkV6, SocketType.Stream, ProtocolType.Tcp);
socket.Bind(ipFinal);
socket.Listen(100);
Socket handler = socket.Accept(); //------> it stops here......nothing happens
