Question

I’m trying to avoid using a long else if statement.

Lets say I have an object and I want to test if it’s of type ClassA, ClassB, ClassC, etc..?

What is a clean way of doing this?

Answer 1

Something like..

if (new[] { typeof(ClassA), typeof(ClassB), typeof(ClassC) }.Contains(obj.GetType()))

?

And obviously if you have a lot of types and are seeing bad performance, then throw it into a dictionary and use ContainsKey.
