Why Interface methods are public by default ?
Why cant we have a protected method in interface ?

推荐答案

接口旨在为继承该类的类提供一个与外界一致的已知接口".定义带有私有方法的接口将毫无意义.

阅读 MSDN文档，以更好地理解为什么会出现这种情况.

An interface is designed to provide a known and consistent "interface" to the outside world for classes that inherit it. There would be little point in having an interface with private methods defined.

Read up on the MSDN Documentation to understand better why this is the case.
