Answer 2

        public void fnMain()
        {
            IPAddress ip = Dns.GetHostAddresses(Dns.GetHostName())[0];
            IPEndPoint host = new IPEndPoint(ip, 9080);
            Socket soc = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            EndPoint p = (EndPoint)host;
            soc.Bind(host);
            while (true)
            {
                byte[] byt = new byte[100];
                soc.ReceiveFrom(byt, ref p);
                string result = System.Text.Encoding.Default.GetString(byt);
                Console.WriteLine(result);
            }        }

Answer 4

IPHostEntry iphostinfo = Dns.GetHostEntry(""); 
IPAddress ip = iphostinfo.AddressList[0]; 
IPEndPoint connectEndPoint = new IPEndPoint(ip, 80); 
socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 
string formatString =""; 
string sendString = string.Format(formatString, "POST", "",      Encoding.Default.GetByteCount(gets), 80, gets); 
byte[] b= System.Text.Encoding.Default.GetBytes(sendString); 
socket.Connect(connectEndPoint); 
socket.Send(b, b.Length, 0);   int port = 20;
string host = "";
IPAddress ip  = IPAddress.Parse(host);
IPEndPoint ipe = new IPEndPoint(ip, port);
 Socket socket=new Socket(AddressFamily.Inte.Network,SocketType.Stream,ProtocolType.Tcp);
socket.Connect(ipe); 
byte[]  byteMessage=Encoding.ASCII.GetBytes("");
socket.Send(byteMessage);
socket.Shutdown(SocketShutdown.Both);
socket.Close();参考
