Full version of the socket server side

The last time the socket server side is just appetizers, this time we put the last code to perfect and append.

The form is as follows

I've rewritten the code according to the information I read.

And a lot of comments on the source code, I hope you can read

 Public partial class Form1:form {public Form1 () {InitializeComponent ();        }//proxy delegate delegate void Flushsocket ();        The collection of all proxy sockets list<socket> agentsocketlist = new list<socket> (); private void Btnopen_click (object sender, EventArgs e) {//Create a Socket object Socket Seversocket =            New Socket (AddressFamily.InterNetwork, SocketType.Stream, protocoltype.tcp); Bind port and IP ipendpoint endPoint = new IPEndPoint (Ipaddress.parse (txtip.text), Int.

Format ("message from client {0}; the other side exited \r\n{1}", socket.                        Remoteendpoint, Txtlog.text);                    })); } else {//assigns a value to the receiving text box Txtlog.text = Stri Ng. Format ("message from client {0}; the other side exited \r\n{1}", socket.                    Remoteendpoint, Txtlog.text); }                    //Close the proxy socket socket.

Remoteendpoint, str, txtlog.text);                })); } else {//assigns a value Txtlog.text = string to the receiving text box. Format ("content from client {0}"; { 1}\R\N{2} ", socket.                Remoteendpoint, str, txtlog.text);        }}}//Send message to client private void Btnsend_click (object sender, EventArgs e) {//Traverse each proxy socket foreach (var sOcket in Agentsocketlist) {//If the connection is maintained, the data is transmitted if (socket.

Here is the display effect

On the right is the client, we can first do not care, after I will write the client, here is used by others to verify the server side.

I use "123" to send and receive, no problem, no bug found
