Question

I have the following code:

switch (objectType)
            {
                case ObjectType.UserReview:
                    return MyMethod<UserReview>();
                case ObjectType.ProfessionalReview:
                    return MyMethod<ProfessionalReview>();
                case ObjectType.Question:
                    return MyMethod<Question>();
                case ObjectType.News:
                    return MyMethod<News>();
                default:
                    throw new ArgumentOutOfRangeException("objectType");
            }

Now I need the same code but for calling another method. Are there any options to implement it without duplication and Reflection?

Answer 1

Sounds like an ideal opportunity to replace conditional with polymorphism. Can you promote ObjectType.UserReview to be a class (it looks like an enum at the moment) and put the switch block as a polymorphic method?
