There are several other reasons why you might want to use interfaces instead of class inheritance:

·         Interfaces are better suited to situations in which your applications require many possibly unrelated object types to provide certain functionality.

·         Interfaces are more flexible than base classes because you can define a single implementation that can implement multiple interfaces.

·         Interfaces are better in situations in which you do not have to inherit implementation from a base class.

·         Interfaces are useful when you cannot use class inheritance. For example, structures cannot inherit from classes, but they can implement interfaces.
