C#: Run external console program as hidden

Question

can anyone tell me how to spawn another console application from a Winforms app, but (A) not show the console window on the screen, and (B) still obtain the standard output of the application? Currently I have something like the following:

  Process SomeProgram = new Process();
  SomeProgram.StartInfo.FileName = @"c:\foo.exe";
  SomeProgram.StartInfo.Arguments = "bar";
  SomeProgram.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  SomeProgram.StartInfo.UseShellExecute = false;
  SomeProgram.StartInfo.RedirectStandardOutput = true;
  SomeProgram.Start();
  SomeProgram.WaitForExit();
  string SomeProgramOutput = SomeProgram.StandardOutput.ReadToEnd();

If I set RedirectStandardOutput to false, then the console app is hidden as expected, but I cannot get the standard output text. However, as soon as I set the RedirectStandardOutput to true, the window stops being hidden, although I am able to get the program's output.

So, I know how to make the console app run hidden, and I know how to get the program's output, but how do I get it to do both?

Many TIA

You are missing the CreateNoWindow property which has to be set to true in your case.
