New to C# and am working through Beginning C# 2012 Programming. There doesn't appear to be a specific forum for it. Anyway, I'm having trouble understanding Ch. 8 "Introduction to Object Oriented Programming". I figure this is a pretty important topic, but I'm not quite grasping when you would use the various elements (Struct, Class, Interfaces,etc.) I've reread the chapter 3 times and sorta get what is going on, but have no idea where and how I would use them. Is that something that is explained further in the book or do I need to totally understand this section before I move on?
