How to pass messages to C# application from JavaScript, I'm able to do this with PHP and tcpListner in c#(but using PHP need server to host), i need localhost communicate c# application with browser(using javaScript or any other possible way), browser need to pass messages to application running on same matchine
can you suggest appropriate method for this with sample
You can do this in the following way.
step 1 : you have to create a Listener. TcpListener class or HttpListener in .net can be used to develop the listener. This code shows how to implement a TCP listener.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Sockets;
using System.Net;
using System.Threading;
//Author : Kanishka
namespace ServerSocketApp
{
class Server
{
private TcpListener tcpListn = null;
private Thread listenThread = null;
private bool isServerListening = false;
public Server()
{
tcpListn = new TcpListener(IPAddress.Any,8090);
listenThread = new Thread(new ThreadStart(listeningToclients));
this.isServerListening = true;
listenThread.Start();
}
//listener
private void listeningToclients()
{
tcpListn.Start();
Console.WriteLine("Server started!");
Console.WriteLine("Waiting for clients...");
while (this.isServerListening)
{
TcpClient tcpClient = tcpListn.AcceptTcpClient();
Thread clientThread = new Thread(new ParameterizedThreadStart(handleClient));
clientThread.Start(tcpClient);
}
}
//client handler
private void handleClient(object clientObj)
{
TcpClient client = (TcpClient)clientObj;
Console.WriteLine("Client connected!");
NetworkStream stream = client.GetStream();
ASCIIEncoding asciiEnco = new ASCIIEncoding();
//read data from client
byte[] byteBuffIn = new byte[client.ReceiveBufferSize];
int length = stream.Read(byteBuffIn, 0, client.ReceiveBufferSize);
StringBuilder clientMessage = new StringBuilder("");
clientMessage.Append(asciiEnco.GetString(byteBuffIn));
//write data to client
//byte[] byteBuffOut = asciiEnco.GetBytes("Hello client! \n"+"You said : " + clientMessage.ToString() +"\n Your ID : " + new Random().Next());
//stream.Write(byteBuffOut, 0, byteBuffOut.Length);
//writing data to the client is not required in this case
stream.Flush();
stream.Close();
client.Close(); //close the client
}
public void stopServer()
{
this.isServerListening = false;
Console.WriteLine("Server stoped!");
}
}
}
Step 2 : you can pass parameters to the created server as a GET request. You can use either JavaScript or HTML Forms to pass parameters. JavaScript libraries like jQuery and Dojo will make it easier to make ajax requests.
http://localhost:8090?id=1133
You have to modify the above code to retrieve the parameters send as a GET request. I recommend to use HttpListener instead of TcpListener
Once you have done with the listening part rest part is just processing the retrieved parameters from the request.
You should use the HttpListener class, or create a self-hosted ASP.Net Web API project.
