Code inspection: Member can be made protected (private accessibility)
ReSharper is smart enough to determine where a particular class member is actually being used. If it isn’t used outside the type or derived types, ReSharper will offer to mark the member as private
. If the member is used in derived classes too, ReSharper will offer to mark it as protected
.
Note that these recommendations need to be considered before being automatically applied. After all, you may be creating a public API, or you may be making types intended to be accessed in non-standard ways (for example, reflection). In this case, constraining visibility might not be a good idea. If necessary, you can always suppress the inspection.
In contrast to the similar solution-wide inspection that also detects unused public members in non-nested types, this local inspection will only notify you about public members in non-public nested types, which are not used in the parent type. This can indicate one of the two problems:
The public member is intended to be protected. In this case, you can apply the quick-fix that ReSharper suggests.
The public member is intended to be used in the parent class but not used there. In this case, the member cannot be a part of a public API and probably hides some not implemented functionality.
