Hi Ben,
I'm not sure I fully understand your question, so please feel free to let
me know.
Per your question:
==========
Specifically, how can the DemonstrateConditions method be implemented by
GoodEats, so that it can be called by HealthBureau and not by
GoodEatsWaiter?
==========
I think that using "protected internal" on the method should be ok for your
requirement. "protected" means it can only be called by inheriting classes.
"internal" means can only be called by the declaring assembly (in this
case, is assembly A). Combining them means it can be called by inheriting
classes or classes in the same assembly.
When you inherit this class in assemly B, you will notice the overridden
method only has signature "protected", we're not allowed to use "internal"
here because "internal" to assembly B means it's callable in assembly B
which will change the visibility and violates compiler error CS0507.
So I think the documentation os CS0507 is correct here.
Please let me know if my understanding of your question is correct or not.
Thanks.
Sincerely,
Walter Wang (wa****@online.microsoft.com, remove 'online.')
