c++ - Read environment variables from a process in C#

Question

I want to read the environment variables of process B from C# code in process A. I have seen some solutions for this in C++ but haven't tried adapting these to C#. Is this possible from C#, and if not, has anyone wrapped a C++ solution yet?

Answer 1

I've skimmed through the links provided by Isalamon and Daniel Hilgarth, and also the code in CLR Profiler's GetServicesEnvironment() method which seems to be doing the same thing, and after a bit of testing found that the most reliable solution is Oleksiy's code (pure C# with P/Invoke) which he published in this blog post. It still has the limitation, where you have to be a 64bit process to read the env vars of another 64bit process.
