By stating that you are inheriting the Collection<T> class, you declare that your class IS-A Collection<T>, meaning that you have all it's API implemented (either by the derived class or by base the Collection<T> class).

In Part 2 of Object-Oriented Programming Concepts and .NET, I will explain the concepts of inheritance, abstraction, and polymorphism. I will also present a Unified Model Language (UML) class diagram to represent an object model that will help as a visual aid to explain some concepts.

Aug 23, 2024 · C# allows the user to inherit one interface into another interface. When a class implements the inherited interface then it must provide the implementation of all the members that are defined within the interface inheritance chain.

Feb 26, 2010 · I'm playing around with some classes and interfaces, and have developed a simple method to determine the hierarchy of a class, i.e. to identify the chain of inheritance.

Feb 3, 2023 · This tutorial introduces you to inheritance in C#. Inheritance is a feature of object-oriented programming languages that allows you to define a base class that provides specific functionality (data and behavior) and to define derived classes that either inherit or …

You can think of an interface as a pure abstract base class that contains no logic, only public method (and property) signatures. So yes, your Sphere has an is-a relationship with IHasVolume, and will behave the same as if you had an abstract HasVolume class that was inherited.

.NET framework provides interfaces that implement by collections in language to provide the functionality of iterating over objects in the collection, adding and removing an object from collection to randomly access an object from the collection.

For a better understanding, please have a look at the below diagram which shows the pictorial representation of different types of Inheritance according to object-oriented programming. We also discussed in our Types of Inheritances article that in C#, with class, only Single, Multi-Level and Hierarchical inheritances are supported.

Learn how interface inheritance works in C#, how to create and implement interfaces that inherit from other interfaces, and best practices for designing interface hierarchies.

Mar 8, 2018 · As you can see from the diagram above of how the classes and Interface inheritance the class IEnumerable. The colored ones are the class files and the white ones are the Interface. IEnumerable<T> and IEnumerable. Provides minimum functionality (enumeration only) ICollection<T> and ICollection.
