All I need is a procedure or method that given a specific wallet file such as mywallet.json and a password to try against it that either returns a valid or not valid response for the password written in C or C# that is complete. No imports.

I could not get pyethrecover to compile for me due to imports either not being found or compiling with errors and it is written in Python.

C# would be the best for me then I can use the Microsoft IDE.
