How to communicate between C and C # application

Question

What would be the best way to communicate between process C and C #. I need to send messages containing commands and parameters, and such from a C # process. to process C. and then process C should send a response.

I am starting a C process in a C # process.

What would be the best way to achieve this? I tried using stdin and stdout, but it didn’t work (for some reason stdin of process C is flashing some line (x (U + 266C) Q) (U + 266C is UTF8 there were sixteen notes brightened )

    psI.CreateNoWindow = true;
    p.StartInfo = psI;
    p.Start();
    sw = p.StandardInput;
    sr = p.StandardOutput;
    sw.AutoFlush = true;
    if (tbComm.Text != "")
        sw.WriteLine(tbComm.Text);
    else
        //execute default command

If you need to run processes in parallel and exchange messages between them, check out our MsgConnect product, which was specifically designed for such tasks.
