Sending input/getting output from a console application (C#/WinForms)

Question

I have a form with 3 controls:

1. A textbox for the user to enter commands to send to a console application,
2. A button to confirm the commands to be sent

Answer 1

I've used code something like this:

    public static void Run(string fileName, string arguments, out string standardOutput, out string standardError, out int exitCode)
    {
        Process fileProcess = new Process();
        fileProcess.StartInfo = new ProcessStartInfo
        {
            FileName = fileName,
            Arguments = arguments,
            RedirectStandardError = true,
            RedirectStandardOutput = true,
            UseShellExecute = false,
            WindowStyle = ProcessWindowStyle.Hidden,
            CreateNoWindow = true,
        };

        bool started = fileProcess.Start();

        if (started)
        {
            fileProcess.WaitForExit();
        }
        else
        {
            throw new Exception("Couldn't start");
        }

        standardOutput = fileProcess.StandardOutput.ReadToEnd();
        standardError = fileProcess.StandardError.ReadToEnd();
        exitCode = fileProcess.ExitCode;

    }

But it's not interactive. But if the app is interactive, it'll take a lot more code anyway.
