Specifying the return type of an abstract method from a Base Class according to a Sub Class

Question

I have the following structure:

abstract class Base {
        public abstract List<...> Get(); //What should be the generic type?
}

class SubOne :         


        

Answer 1

I don't think you can get it to be the specific subclass. You can do this though:

abstract class Base {
        public abstract List Get(); 
}
class SubOne : Base {
    public override List Get() {
        throw new NotImplementedException();
    }
}
class SubTwo : Base {
    public override List Get() {
        throw new NotImplementedException();
    }
}
