为什么我们在接口中不使用私有或受保护的访问修饰符 [英] Why we wont use private or protected access modifier in Interface

问题描述

Hi ,

 As we know Interface in C#. Its accessmodifier is Public by default. My question is why we wont use private or protected as access modifier in Interface. Please reply me with example.

推荐答案

因为，粗略地说，接口抽象了实际实现，而private和protected访问修饰符通常与实现完全相关.
该接口是合同，因此必须完全可访问.

Because, roughly speaking, an interface abstracts the actual implementation, while private and protected access modifiers typically pertain the very implementation.
The interface is a contract, hence it has to be fully accessible.
