How to find out if a IIS property is inherited

Question

How do you tell if a PropertyValueCollection property is inherited ?

Property examples could be:

AccessFlags = 517
AppRoot = /LM/W3SVC/18233351908/ROOT/

I just need a C# way to tell if a property is inherited. I use Metabase Explorer to view properties but i need to do this programatically.

I've tried with methods from the Reflection namespace without much luck :-(

Best Regards
