Start a process in the same console

Question

Can I start a process (using C# Process.Start()) in the same console as the calling program? This way no new window will be created and standard input/output/error will be the same as the calling console application. I tried setting process.StartInfo.CreateNoWindow = true; but the process still starts in a new window (and immediately closes after it finishes).

You shouldn't need to do anything other than set UseShellExecute = false, as the default behaviour for the Win32 CreateProcess function is for a console application to inherit its parent's console, unless you specify the CREATE_NEW_CONSOLE flag.

I tried the following program:

private static void Main() {     Console.WriteLine( "Hello" );      var p = new Process();     p.StartInfo = new ProcessStartInfo( @"c:\windows\system32\netstat.exe", "-n" )          {             UseShellExecute = false         };      p.Start();     p.WaitForExit();      Console.WriteLine( "World" );     Console.ReadLine(); } 

and it gave me this output:
