Good day,
I've been trying to get the value of inheritance class name of other inheritance class in Roslyn API.

like below picture,

when I'm scanning the 'Face' class, I want to get the name of "Human".
like this structure, I can get the first inheritance class name by using ClassDeclaration.BaseList. I can get the name of "Head" from Face class!

But I can't access the second inheritance class(Human class). I think that there's no more tree structure in Face class.

The question point is that the way how to get 2-layer upper(or more) inheritance class name if in case of the classes are seperated.

Thank you.
