Let's say I have a bunch of classes that inherits the "Animal" class (using a simple example so it's easier to explain)...

All my classes (ex: Gorilla, Dog etc..) have the Growl() method...

Is there a way I can hold a list or collection of "animals" (no matter if it's a dog or a gorilla) so I can do something like

animalList.Add(new Dog());
animalList.Add(new Gorilla());

and then call animalList[0].Growl();

Again, sorry for the stupid example, but I thought it would make my question easier to understand

I don't really mind if I have to use a Collection or a List or any other type of collection... as long as I can add different (but similar) objects to it, and call common methods on them...
