c# - 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:windowssystem32
etstat.exe", "-n" ) 
        {
            UseShellExecute = false
        };

    p.Start();
    p.WaitForExit();

    Console.WriteLine( "World" );
    Console.ReadLine();
}

and it gave me this output:
