Redirect the standard input and output of .net program

I a开发者_如何学运维m writing a test script for a C/S system in python. And right now, we only have a test client written in C#. It is a command line based client. I want to control the input and get the output of the client in my python script. How could I make it?

Thanks!

Use the subprocess module as follows:

import subprocess

proc = subprocess.Popen("cat", stdin = subprocess.PIPE, stdout = subprocess.PIPE)

out, err = proc.communicate(input)

The process ends after the last call. If you want to do some input iteratively, you can use proc.stdin.write, but you have to call communicate(None) at the end to finish the process.

Use subprocess.Popen.
