Interface

Question

Hi, Ques What is the Interface in the .Net 5.0 ?

Senthilkumar · Answer

There is no .net 5.0. The interface is object oriented design and mostly it will not be changed when the framework new version comes. The interface is pure abstract type in .net. It will have only the structure and there is no implementation. It cannot have any constructors and destructors. It can inherit from another interfaces. This is only way to support multiple inheritance in C#. It is used to implement the generality or commonality across the system. It will not allow to create the object directly and inherited class should implement all the methods. The public is the default access modifier and it will not allow. It will allow to use the indexer, property, events and methods.

The first point is that (as yet) there's no .NET 5.0, but there is a .NET 4.5 which is still in beta. An interface in any version of .NET is a collection of method, property, indexer or event declarations. However, an interface contains only the signatures of such members, not their implementations. It is also an error to include any access modifiers as all interface members are implicitly public. However, a class or struct which implements the interface must provide public implementations of all the interface's members.
