Redirecting Standard Input Output For Telnet Window

[2MuchRiceMakesMeSick]

Can someone tell me why this doesnt work with telnet?

Process p = new Process();
StreamWriter sw;
StreamReader sr;
StreamReader err;

ProcessStartInfo psI = new ProcessStartInfo(@"c:\windows\system32\telnet.exe");
psI.UseShellExecute = false;
psI.RedirectStandardInput = true;
psI.RedirectStandardOutput = true;
psI.RedirectStandardError = true;
p.StartInfo = psI;

p.Start();
sw = p.StandardInput;
sr = p.StandardOutput;
err = p.StandardError;

sw.Close();

textBox1.Text = sr.ReadToEnd();
textBox1.Text += err.ReadToEnd();

It just opens a cmd prompt really quick and then closes?

Does anyone know how to redirect the I/O of a telnet window?
