c# - TcpListener - 无法建立连接，因为目标机器主动拒绝它

Question

        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);

此代码在我的 PC 上运行时在最后一行失败，出现“无法建立连接，因为目标机器主动拒绝它”异常。任何想法可能是什么原因以及如何解决它？

解决方案是使用指定的 AddressFamily 参数创建客户端套接字:

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