C# - List Folder Permissions / Compare / Write to File

Question

I have a problem with another Administrator giving certain members permissions there not allowed to have.

I want to create a script that will Scan the Home folder directory looking at the folder permissions for each users Home folder.  If the users permissions do not match to read/write only then write the account name and folder path to a log file.

I have only moderate knowledge in C# and would like to ask about how one would accomplish this task roughly.

--Thanks
