Binary data communication based on NetworkComms V3, networkcomms

Binary data communication based on NetworkComms V3, networkcomms

If both the client and the server are in the C # language, you can use the protobuf serialization method encapsulated by the NetworkComms V3 framework or the BinaryFormater serialization method, which is convenient.

Just now I discussed with my friends how to communicate with other languages based on networkComms V3, and transfer a binary array between the client and the server.

In this example, the C # client and server transmit binary data to simulate communication with other languages.

Server code:

Using System; using System. collections. generic; using System. componentModel; using System. data; using System. drawing; using System. text; using System. windows. forms; using NetworkCommsDotNet. DPSBase; using NetworkCommsDotNet. tools; using NetworkCommsDotNet. connections; using NetworkCommsDotNet. connections. TCP; using System. net; namespace RawServer {public partial class Form1: Form {S EndReceiveOptions sro = new SendReceiveOptions (DPSManager. getDataSerializer <NullSerializer> (), null, null); public Form1 () {InitializeComponent ();} private void button#click (object sender, EventArgs e) {// The server starts listening to client requests // starts listening to a port // communication with other languages disable ApplicationLayerProtocolStatus TCPConnectionListener listener = new TCPConnectionListener (sro, ApplicationLayerProtocolStatus. disabled); Connection. startList Ening (listener, new IPEndPoint (IPAddress. parse (txtIP. text), int. parse (txtPort. text); button1.Text = "listening"; button1.Enabled = false; // This method contains the specific server processing method. StartListening ();} private void StartListening () {NetworkComms. disableLogging (); // array receives the byte NetworkComms. appendGlobalIncomingUnmanagedPacketHandler (header, connection, array) =>{// you can parse the byte array in this method, and then process LogInfo Based on Different Types after parsing. logMessage ("create log file", "log .txt"); for (int I = 0; I <array. length; I ++) {LogInfo. logMessage (I. toString () + "-" + array [I]. toString (), "log. txt");} // After receiving a message from the server, if you need to return data to the client, the following code can be used to simulate a data // byte [] dataToSend = new byte [] {5, 6, 7, 8}; // connection. sendUnmanagedBytes (dataToSend) ;});} private void form=formclosing_1 (object sender, FormClosingEventArgs e) {NetworkComms. shutdown (); Environment. exit (Environment. exitCode );}}}View Code

Client code:

Using System; using System. collections. generic; using System. componentModel; using System. data; using System. drawing; using System. text; using System. windows. forms; using NetworkCommsDotNet. DPSBase; using NetworkCommsDotNet. tools; using NetworkCommsDotNet. connections; using NetworkCommsDotNet. connections. TCP; using System. net; namespace RawClient {public partial class Form1: Form {SendReceiveOptions sro = new SendReceiveOptions (DPSManager. getDataSerializer <NullSerializer> (), null, null); // Connection information class public ConnectionInfo connInfo = null; // Connection class newTcpConnection; public Form1 () {InitializeComponent ();} private void button1_Click_1 (object sender, EventArgs e) {connInfo = new ConnectionInfo (txtIP. text, int. parse (txtPort. text), ApplicationLayerProtocolStatus. disabled); // if it fails, the exception message newTcpConnection = TCPConnection will pop up. getConnection (connInfo, sro); button1.Enabled = false; button1.Text = "connection successful";} private void button2_Click (object sender, EventArgs e) {byte [] dataToSend = new byte [] {1, 2, 3, 4}; newTcpConnection. sendUnmanagedBytes (dataToSend);} private void form=formclosing (object sender, FormClosingEventArgs e) {NetworkComms. shutdown (); Environment. exit (Environment. exitCode);} private void Form1_Load (object sender, EventArgs e) {}// if you want to process messages sent from the server, you can listen to and analyze data on the server }}View Code

Server listening:

 

// Disable ApplicationLayerProtocolStatus TCPConnectionListener listener = new TCPConnectionListener (sro, ApplicationLayerProtocolStatus. disabled); Connection. startListening (listener, new IPEndPoint (IPAddress. parse (txtIP. text), int. parse (txtPort. text); button1.Text = "listening"; button1.Enabled = false; // This method contains the specific server processing method. StartListening ();

Listener method:

Private void StartListening () {NetworkComms. disableLogging (); // array receives the byte NetworkComms. appendGlobalIncomingUnmanagedPacketHandler (header, connection, array) =>{// you can parse the byte array in this method, and then process LogInfo Based on Different Types after parsing. logMessage ("create log file", "log .txt"); for (int I = 0; I <array. length; I ++) {LogInfo. logMessage (I. toString () + "-" + array [I]. toString (), "log. txt");} // After receiving a message from the server, if you need to return data to the client, the following code can be used to simulate a data // byte [] dataToSend = new byte [] {5, 6, 7, 8}; // connection. sendUnmanagedBytes (dataToSend );});}

Client Connection server code:

ConnInfo = new ConnectionInfo (txtIP. text, int. parse (txtPort. text), ApplicationLayerProtocolStatus. disabled); // if it fails, the exception message newTcpConnection = TCPConnection will pop up. getConnection (connInfo, sro); button1.Enabled = false; button1.Text = "connection successful ";

Code used by the client to send byte Bytes:

 private void button2_Click(object sender, EventArgs e)        {            byte[] dataToSend = new byte[] { 1, 2, 3, 4 };            newTcpConnection.SendUnmanagedBytes(dataToSend);                     }

For the convenience of observation, the data received by the server is written into a text file:

Create a log file 0-11-22-33-4
