I am using VB.Net. I have an object class called clsA(of T as clsB). Depending on what T is, I want to do different things. Let's say that clsC and clsD both inherit clsB and therefore can be used for T. If I have an instance of clsA(of clsC), how can I get the inside type (i.e. clsC) using reflection? Solutions in C#.Net would be fi...
