在c#中需要有关组播udp服务器发现的帮助

作为这个问题的后续问题,我已经在我的本地机器上运行了一个解决方案,但是没有在网络上的机器上运行.

我不太了解那些基础知识以外的插座,所以请耐心等待.目标是让客户端在本地网络上查找服务器,这是一些剪切/粘贴/编辑代码的结果.

这是客户端代码:

IPEndPoint ipep = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 10294);

    byte[] data = new byte[1024];
    public Form1()
    {
        InitializeComponent();

    }

    private void button1_Click(object sender, EventArgs e)
    {

        Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
        client.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.MulticastTimeToLive, 10);
        string welcome = "What's your IP?";
        data = Encoding.ASCII.GetBytes(welcome);
        client.SendTo(data, data.Length, SocketFlags.None, ipep);
        IPEndPoint server = new IPEndPoint(IPAddress.Any, 0);
        EndPoint tmpRemote = (EndPoint)server;
        data = new byte[1024];
        int recv = client.ReceiveFrom(data, ref tmpRemote);
        this.IP.Text = ((IPEndPoint)tmpRemote).Address.ToString(); //set textbox
        this.Port.Text = Encoding.ASCII.GetString(data, 0, recv); //set textbox
        client.Close();
    }

这是服务器代码:

int recv;
        byte[] data = new byte[1024];
        IPEndPoint ipep = new IPEndPoint(IPAddress.Any, 10294);
        Socket newsock = new Socket(AddressFamily.InterNetwork,
                SocketType.Dgram, ProtocolType.Udp);
        newsock.Bind(ipep);
        newsock.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.AddMembership, new MulticastOption(IPAddress.Any,IPAddress.Parse("127.0.0.1")));

        while (true)
        {
            Console.WriteLine("Waiting for a client...");
            IPEndPoint sender = new IPEndPoint(IPAddress.Any, 0);
            EndPoint tmpRemote = (EndPoint)(sender);
            data = new byte[1024];
            recv = newsock.ReceiveFrom(data, ref tmpRemote);
            Console.WriteLine("Message received from {0}:", tmpRemote.ToString());
            Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv));
            string welcome = "7010";
            data = Encoding.ASCII.GetBytes(welcome);
            newsock.SendTo(data, data.Length, SocketFlags.None, tmpRemote);
        }

它可以在我的本地机器(服务器和客户端)上查找,但当我在同一网络上尝试另一台机器时,我得到"现有连接被远程主机强行关闭"

我意识到我需要添加很多try/catch,但我只是想先了解一下这是如何工作的.
