TcpListener-无法建立连接，因为目标计算机主动拒绝了它 [英] TcpListener - No connection could be made because the target machine actively refused it

问题描述

        int port = 44344;

        var thread = new Thread(
            () =>
            {
                TcpListener listener = null;
                try
                {
                    listener = new TcpListener(IPAddress.Any, port);
                    listener.Start();

                    while (true)
                    {
                        var client = listener.AcceptTcpClient();
                    }
                }
                catch (ThreadInterruptedException)
                { }

                if (listener != null)
                    listener.Stop();
            });
        thread.Start();

        Thread.Sleep(TimeSpan.FromSeconds(1));

        var socket = new Socket(SocketType.Stream, ProtocolType.IP);
        socket.Connect("localhost", port);

在我的PC上运行时，此代码在最后一行失败，并带有由于目标计算机主动拒绝连接而无法建立连接"异常.有什么想法是什么原因以及如何解决?

This code fails on the last line with "No connection could be made because the target machine actively refused it" exception, when running on my PC. Any ideas what can be the reason and how to fix it?

推荐答案

解决方案是使用指定的AddressFamily参数创建客户端套接字:

The solution was to create the client socket with an AddressFamily parameter specified:

var socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
