Hi Hemanth,
This isn't really IronPython specific, so finding a similar solution
in C# you should be able to translate it fairly easily. In this case I
think you need to use the OutputDataReceived event and call
BeginOutputReadLine to start the process, then handle the output
events from the event handler.

Alternatively, call ReadLine in a separate thread so that it doesn't
block. This is a bit tricky to get right, so the event approach is
probably better depending on what you need to do with the output.
