C# Generics Inheritance Problem

Question

I\'d like to add different types of objects derived from one class with generics into a List of base type. I get this compile error

Error   2   Argument 1: c         


        

Answer 1

You can do this using covariance and contravariance, but your ShelterBase class needs to derive from an interface, since only interfaces can be co- or contravariant. You list will need to be a List> and it should work.
