c# - "Can´t open socket or connection refused"与 .NET

Question

当我尝试使用 netcat 将一些数据发送到我的服务器应用程序时，连接被拒绝。

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

Answer 1

问题已解决，我必须在数组中移动 1 个位置，因为第一个位置指向 IPv6 地址。

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
