Using binary data communication based on Networkcomms V3

If both the client and the server are C # languages, it is convenient to use the Networkcomms V3 Framework, the PROTOBUF serialization of the wrapper, or the Binaryformater way to serialize it.

Just talking to a friend. Based on Networkcomms V3 communicates with other languages, a binary array is passed between the client and server side.

This example implements the C # client-server delivery of binary data to mimic communication with other languages

Server-side code:

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Text;usingSystem.Windows.Forms;usingnetworkcommsdotnet;usingnetworkcommsdotnet.dpsbase;usingNetworkcommsdotnet.tools;usingnetworkcommsdotnet.connections;usingNetworkCommsDotNet.Connections.TCP;usingSystem.Net; namespacerawserver{ Public Partial classform1:form {sendreceiveoptions SRO=NewSendreceiveoptions (dpsmanager.getdataserializer<nullserializer> (),NULL,NULL);  PublicForm1 () {InitializeComponent (); }        Private voidButton1_Click (Objectsender, EventArgs e) {            //server starts listening for client requests//start listening on a port//communication with other languages disabled ApplicationlayerprotocolstatusTcpconnectionlistener listener=NewTcpconnectionlistener (sro,applicationlayerprotocolstatus.disabled); Connection.startlistening (Listener,NewIPEndPoint (Ipaddress.parse (Txtip.text),int.                      Parse (Txtport.text)); Button1. Text="Listening in"; Button1. Enabled=false; //This method contains server-specific processing methods. startlistening (); }        Private voidstartlistening () {networkcomms.disablelogging (); //Array received bytesNetworkcomms.appendglobalincomingunmanagedpackethandler (header, connection, array) =            {                //The byte array can be parsed in this method, parsed out and then processed by different typesLoginfo.logmessage ("Create a log file","log. txt");  for(inti =0; I < array. Length; i++) {loginfo.logmessage (i.tostring ()+" - "+ Array[i]. ToString (),"log. txt"); }                //after receiving the server message, if you need to return data to the client, you can use code similar to the following//simulate a data//byte[] datatosend = new byte[] {5,6,7,8}; //connection. Sendunmanagedbytes (Datatosend);             }); }             Private voidForm1_formclosing_1 (Objectsender, FormClosingEventArgs e)            {Networkcomms.shutdown ();        Environment.exit (Environment.exitcode); }    }}

Server-Side monitoring:

 //  communication with other languages Disable Applicationlayerprotocolstatus  tcpconnectionlistener listener=new Tcpconnectionlistener (sro,applicationlayerprotocolstatus.disabled); Connection.startlistening (Listener,  int   =   listen   " ; Button1.            Enabled  = false  ;  //  startlistening (); 

Monitoring method:

Private voidstartlistening () {networkcomms.disablelogging (); //Array received bytesNetworkcomms.appendglobalincomingunmanagedpackethandler (header, connection, array) =            {                //The byte array can be parsed in this method, parsed out and then processed by different typesLoginfo.logmessage ("Create a log file","log. txt");  for(inti =0; I < array. Length; i++) {loginfo.logmessage (i.tostring ()+" - "+ Array[i]. ToString (),"log. txt"); }                //after receiving the server message, if you need to return data to the client, you can use code similar to the following//simulate a data//byte[] datatosend = new byte[] {5,6,7,8}; //connection. Sendunmanagedbytes (Datatosend);             }); }

The code for the client's connection server:

New int . Parse (Txtport.text), applicationlayerprotocolstatus.disabled);             // if not successful, the exception message            pops up Newtcpconnection = tcpconnection.getconnection (CONNINFO,SRO);             false ;             " Connection Successful ";

The client sends the code for byte byte data:

Private void button2_click (object  sender, EventArgs e)        {            bytenew  byte1234  };            Newtcpconnection.sendunmanagedbytes (datatosend);                     }

The data received by the server is written in a text file for ease of observation:

Create a log file 0 1 1 2 2 3 3 4
