c#客户端和服务器端通信问题

Question

服务端ip：192.168.1.214。客户端ip：192.168.1.30
客户端代码public static void ReceiveStart(string localip, string localPort)
{
try
{
//创建接受套接字
IPAddress localIP = IPAddress.Parse(localip);
IPEndPoint localIPEndPoint = new IPEndPoint(localIP, int.Parse(localPort));
receiveUdpClient = new UdpClient(localIPEndPoint);
//启动接受线程
Thread threadReceive = new Thread(ReceiveMessages);
threadReceive.IsBackground = true;
threadReceive.Start();
}
catch (Exception ex)
{
MessageBox.Show("错误类型："+ex.ToString());
}
}

    private static void ReceiveMessages()
    {
        IPEndPoint remoteIPEndPoint = new IPEndPoint(IPAddress.Any, 0);
        while (true)
        {
            try
            {
                //关闭receiveUdpClient时此句会产生异常

                byte[] receiveBytes = receiveUdpClient.Receive(ref remoteIPEndPoint);
                /*for (int i = 0; i < receiveBytes.Length; i++)
                {
                    ShwMsgForView.ShwMsgforView(listBox, string.Format("{0}[{1}]", remoteIPEndPoint, receiveBytes[i].ToString()));
                }*/
                // string message = Encoding.Unicode.GetString(receiveBytes, 0, receiveBytes.Length);
                string message = Encoding.ASCII.GetString(receiveBytes, 0, receiveBytes.Length);
                //显示接受到的消息内容
                //ShwMsgForView.ShwMsgforView(listBox, string.Format("{0}[{1}]", remoteIPEndPoint, message))
                label_dis.Text = message;
            }
            catch
            {
                break;
            }
        }
    }
            然后我用一个button调用他，输入ip是192.168.1.30，port使用的是8099.检测port口没有被占用。打开程序后点击button调用报错：socket的问题，说是在其上下文中该地址无效。我查了下网上的解答，说是要配置路由，但是路由是公用的我不好其配置。。。有没有其他解决方法。

很可能你的客户端机器的ip不是192.168.1.30。

解决方法就是你地址绑定的时候直接同通配符：

IPEndPoint localIPEndPoint = new IPEndPoint(**IPAddress.Any**, int.Parse(localPort));
