C# cmd

Anyone know if its possible to open a command prompt screen from within a C# program and pass commands from the program to the command prompt?

Depends on what you are trying to do...

A hackish way (which may or may not work) would be to use a System.Diagnostics.Process and redirect the Input and Output streams. Then use the process to start "cmd" or "command" and then send your command through the redirected input. Finally read the result from the Output stream.

i.e.
Process p = new Process;
p.Options.RedirectInput = true;
p.Options.RedirectOutput = true;

p.Start("cmd.exe");
p.Input.WriteLine("myCommand.exe");
string s = p.Output.Readline();
**keep reading until no more output**.

It's psuedo code, so that actual class will have different names for the options and whatnot

Also, you can set it to not pop up the console window if you don't want it to appear.

im looking for a legit way to do it as im testing to see if i can create a cmd window then run a telnet session through it instead of using a telnet library.

Well, if you do it that way, you've just locked yourself into windows only. A slightly more direct way would be just to launch telnet directly:

Process p = new Process();
p.StartInfo.CommandLine = "telnet.exe";
p.Start();

Then just redirect the input and output and disable the creation of the console window and you're sorted. This way will work, i did it before so i could create a quick program that would ping for 2 days straight so some statistical analysis could be performed on the packetloss. (college assignment).
