How to work with an interface in VB.NET?


Interfaces allow us to create definitions for component interaction. They also provide another way of implementing polymorphism. Through interfaces, we specify methods that a component must implement without actually specifying how the method is implemented.

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.
