Question

I have two method overloads:

bool HasRight(RightType rightType, string cityId);
bool HasRight(RightType rightType, string cityAlias);

Of course it won’t compile as methods signatues are the same. What is the best way to solve naming problem in this case?

Answer 1

Would you immediately be able to distinguish between an id and an alias? How about simply:

bool HasRight(RightType rightType, string cityIdOrAlias)

If it isn’t clear cut, something like “if it starts with :, for example :nyc, then it is an id, else it is assumed to be an alias”. Other options:

• suffixed names:

  bool HasRightById(RightType rightType, string cityId)
  bool HasRightByAlias(RightType rightType, string cityAlias)
  

• take both and demand exactly one inside the method:

  bool HasRight(RightType rightType, string cityId, string cityAlias)
