Is a switch statement applicable in a factory method? c#

Question

I want to return an Interface and inside a switch statement I would like to set it. Is this a bad design?

private IResultEntity GetEntity(char? someType)
            


        

Answer 1

It's not bad, it's almost exactly the same as an example (Parameterized Factory Method) in the Gang of Four Bible itself.

I used to think that switch statements are a code smell, they are not, they have their place in any OO language.
