Using bash(cygwin) inside C# program


Hey everyone,

i need to use bash shell "inside" C# program. I want to mimic user typing in
interactive mode and running cygwin commands.
i created a process that runs bash and redirect stdin,stout and std error
but I can?t get tty to work attached is a sample code that starts bash
process and redirect the input/output.
the problem is that i don't have tty device. if i try to run tty command or
stty command i receive error response 
tty - not a tty 
stty - Inappropriate ioctl for device

i think the this is caused from psi.UseShellExecute = false; 
i need to run cygwin and disable echo with stty -echo but to do this i need
a tty device. how can i create a cygwin bash shell with tty device and
redirect the stdin, out and error ?

Here is simplified code:

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading;

namespace shartCygwin
{
? ? class Program
? ? {
? ? ? ? private static Queue<string> ResponseQueue = null;
? ? ? ? private static ManualResetEvent ResponseEvent = null;

? ? ? ? static void Main(string[] args)
? ? ? ? {
? ? ? ? ? ? ResponseQueue = new Queue<string>();
? ? ? ? ? ? ResponseEvent = new ManualResetEvent(false);

? ? ? ? ? ? Process bashProcess = new Process();

? ? ? ? ? ? bashProcess.StartInfo.FileName = "C:\\cygwin\\bin\\bash.exe"; 
? ? ? ? ? ? bashProcess.StartInfo.Arguments = "--login -i "; ?
? ? ? ? ? ? bashProcess.StartInfo.WorkingDirectory = "C:\\cygwin\\bin";

? ? ? ? ? ? bashProcess.StartInfo.EnvironmentVariables["CYGWIN"] = "tty";

? ? ? ? ? ? bashProcess.StartInfo.RedirectStandardError = true;
? ? ? ? ? ? bashProcess.StartInfo.RedirectStandardInput = true;
? ? ? ? ? ? bashProcess.StartInfo.RedirectStandardOutput = true;
? ? ? ? ? ? bashProcess.StartInfo.CreateNoWindow = true;
? ? ? ? ? ? bashProcess.StartInfo.UseShellExecute = false;
? ? ? ? ? ? bashProcess.StartInfo.ErrorDialog = false;

? ? ? ? ? ? bashProcess.Start();

? ? ? ? ? ? DataReceivedEventHandler errorEventHandler = new
DataReceivedEventHandler(ErrorDataReceived);
? ? ? ? ? ? DataReceivedEventHandler outEventHandler = new
DataReceivedEventHandler(OutDataReceived);
? ? ? ? ? ? bashProcess.OutputDataReceived += outEventHandler;
? ? ? ? ? ? bashProcess.ErrorDataReceived += errorEventHandler;
? ? ? ? ? ? bashProcess.BeginErrorReadLine();
? ? ? ? ? ? bashProcess.BeginOutputReadLine();

? ? ? ? ? ? while(true)
? ? ? ? ? ? {
? ? ? ? ? ? ? ? Thread.Sleep(1000);
? ? ? ? ? ? }
? ? ? ? }

? ? ? ? static void ErrorDataReceived(object sender, DataReceivedEventArgs
dataReceivedEventArgs)
? ? ? ? {
? ? ? ? ? ? try
? ? ? ? ? ? {
? ? ? ? ? ? ? ? lock (ResponseQueue)
? ? ? ? ? ? ? ? {
? ? ? ? ? ? ? ? ? ? Console.WriteLine(dataReceivedEventArgs.Data);
? ? ? ? ? ? ? ? ? ? ResponseQueue.Enqueue(dataReceivedEventArgs.Data);
? ? ? ? ? ? ? ? ? ? ResponseEvent.Set();
? ? ? ? ? ? ? ? }
? ? ? ? ? ? }
? ? ? ? ? ? catch (Exception e)
? ? ? ? ? ? {
? ? ? ? ? ? ? ? Console.WriteLine(e.Data);
? ? ? ? ? ? }
? ? ? ? }

? ? ? ? static void OutDataReceived(object sender, DataReceivedEventArgs
dataReceivedEventArgs)
? ? ? ? {
? ? ? ? ? ? try
? ? ? ? ? ? {
? ? ? ? ? ? ? ? lock (ResponseQueue)
? ? ? ? ? ? ? ? {
? ? ? ? ? ? ? ? ? ? Console.WriteLine(dataReceivedEventArgs.Data);
? ? ? ? ? ? ? ? ? ? ResponseQueue.Enqueue(dataReceivedEventArgs.Data);
? ? ? ? ? ? ? ? ? ? ResponseEvent.Set();
? ? ? ? ? ? ? ? }
? ? ? ? ? ? }
? ? ? ? ? ? catch (Exception e)
? ? ? ? ? ? {
? ? ? ? ? ? ? ? Console.WriteLine(e.Data);
? ? ? ? ? ? }
? ? ? ? }
? ? }
}
