How do I check whether a user is allowed to read / write a particular registry key?

Question

Does anybody know how I can programmatically check (using C#) whether my program will be able to read / write a particular registry key (specifically: \"SOFTWARE\\Microsoft\

Answer 1

Just try to open the registry key with WRITE permissions.

That said, what others have said is right: There is no way to tell if an operation is going to succeed unless you try it. Maybe someon deleted the Run key. Maybe the registry will exceed allocated memory. Maybe the disk failed.
