Open new cmd from console application and write text in the new Cmd

[sreedhar82]

Hi,
I want to open one new CMD from console application, write text into the new CMD and then coming back to the control on the old cmd. (like interactively working on the both)

please look into the below code

Process P1 = Process.Start(@"C:\WINDOWS\system32\cmd.exe");
P1.StartInfo.RedirectStandardInput = true;
P1.StartInfo.RedirectStandardOutput = true;
P1.StartInfo.UseShellExecute = false;
StreamWriter wr = P1.StandardInput;
wr.WriteLine("First line in New Cmd");
Console.WriteLine("First line in Old Cmd");
wr.WriteLine("Second line in New Cmd");
Console.WriteLine("Second line in Old Cmd");

it is giving the exception "StandardIn has not been redirected"

Please help me on this issue

You can't start a process and then set it's StartInfo parameters. It's too late by then, you've already started the process. Also, you're redirected the output but haven't specified where.
