Calling a generic method with a dynamic type [duplicate]

Answer 1

List animals = 
 creator.CreateAnimals(5);

In the above line from your example, animalType and type are run time variables, not types, so this is of course nonsense. A generic version only makes sense, if you know the types at compile time, e.g.:

List animals = 
  creator.CreateAnimals(5);

where you'd have to constraint types accordingly. If the types are not known, you have to rely completely on reflection...
