Object-oriented Programming in C#
Abstract classes, Interfaces, and Patterns

An interface corresponds to a fully abstract class. No matters of substance is found in the interface, just declarations of intent

An interface describes signatures of operations, but it does not implement any of them

  • Interfaces

    • Classes and structs can implement one or more interfaces

    • An interface can be used as a type, just like classes

      • Variables and parameters can be declared of interface types

    • Interfaces can be organized in multiple inheritance hierarchies
