Extension Methods Interfaces - Course C# 4.0 – Lesson 5 | .net courses

In this video, Normally we write extension methods for classes, but in this example, we will see how that works with interfaces.

Duration:  16 minutes

Summary: In this video, Normally we write extension methods for classes, but in this example, we will see how that works with interfaces. We create a Student class, and an IStudent interface. The class StudentCollection implements the IStudent interface. The static class StudentExtension adds an extension method to the IStudent interface. In Main(), we create a StudentCollection and add students to it. Then, we show in two different ways how to call the PrintStudent() extension method.

Methodology of the development of example: Good coding standard and simplified design.

Technology Used: C# 4.0

Keywords: C#, System, class, interface, new, override, List, extension method.
