I need to pass in an argument that is of a base class type, eg: if I have the following two classes:
Dog : Animal(of Dog)
Animal(Of T as Animal(Of T)) : BusinessBase(Of T)
And I want declare a variable of type Animal (the base class), how would that look?
skagen00 replied on Friday, July 10, 2009Of the base class? You can't. Because Animal is a generic.
What I tend to do when I have generics in the hierarchy is give them an IAnimal interface. Applying IAnimal on the Animal<> class mean that anything that descends from Animal<> will be an IAnimal.
Then, you can have an IAnimal typed variable in Dog (if that's your goal). The members of IAnimal can be the various methods & properties declared/implemented in Animal<>.
