In this class, we will explain the static member, and how to use it in classes, variable, methods, and other members. C# Static Members In C#, static keyword can be used with classes, variables, properties, operators, methods, event and constructors. For classes, the static keywords will make it non-instantiable, meaning the class can’t have an... » read more
In this lesson, you will learn about interface in C# with example. Also, you will learn the difference between abstract class and interface. Definition of Interface Interfaces are objects in C# that looks as same as a class, but with no implementations. In other words, the interface contains a declaration or signature of methods, events,... » read more
In this lesson, you will learn about abstract classes with example. Also, you will learn when to use abstract classes in your program.
