Is it possible to capture/redirect the standard output of a process that I did not launch, in .net?

Question

If I know the process identifier, is there some mechanism in .net (or pinvoke as last resort) to capture/redirect the standard output of a process that I did not launch?

Answer 1

You could AttachConsole your process to the console of the other process, and then use the usual console I/O functions to read and write from it.

Remember to use FreeConsole to detach from the process' current console first.
