Is there a reason you can not define the access modifier on a method or in an interface?

Question

The responsibility of the visibility of a method is relegated to the class that implements the interface.

public interface IMyInterface
{
  bool GetMyInfo(st         


        

Answer 1

In terms of OO - encapsulation is all about data hiding. That means whatever goes on inside a class is up to the class implementation. Which means it would be useless to contractually enforce private members.

However, the reason one uses interfaces is because you want to ensure a class adheres to a specific contract and exposes several public members in a consistent way.
