What is the easiest way to do inter process communication in C#?

Question

I have two C# applications and I want one of them send two integers to the other one (this doesn\'t have to be fast since it\'s invoked only once every few seconds).

Answer 1

I created a simple class which uses IpcChannel class for the inter process communication. Here is a link to a Gist at GitHub.

The server side code:

       IpcClientServer ipcClientServer = new IpcClientServer();
       ipcClientServer.CreateServer("localhost", 9090);

       IpcClientServer.RemoteMessage.MessageReceived += IpcClientServer_MessageReceived;
    
    

The event listener:

    private void IpcClientServer_MessageReceived(object sender, MessageReceivedEventArgs e)
    {
        if (InvokeRequired)
        {
            Invoke(new MethodInvoker(delegate { textBox2.Text += e.Message + 
            Environment.NewLine; }));
        }
        else
        {
            textBox2.Text += e.Message + Environment.NewLine;
        }
    }

The client:

        if (ipcClientServer == null)
        {
            ipcClientServer = new IpcClientServer();
            ipcClientServer.CreateClient("localhost", 9090);
        }
        ipcClientServer.SendMessage(textBox1.Text);

Note: A reference to a System.Runtime.Remoting is required.
