Senior .Net Developer Interview Question:
Explain me what is the difference between an abstract class and an interface?
Submitted by: MuhammadAn abstract class is always used as a base class. It provides some abstract/virtual members that the inheriting entities must implement, as well as a partial implementation for a functionality. For extra credit, job candidates might mention that this class can also declare fields. Developers cannot create an object from this class.
An interface, on the other hand, can declare properties, methods and events only (no access modifiers). The developer must implement all declared members. In short, an interface designates a contract/behavior that implementing classes should have.
