In C#, we cannot create objects of an abstract class. We use the abstract keyword to create an abstract class. In this tutorial, we will learn about C# abstract class and method with the help of examples.
7 Αυγ 2023 · An abstract class in C# is a class that cannot be instantiated on its own. It serves as a blueprint for other classes, known as derived classes. Abstract classes are designed to be inherited, and they can contain both abstract and concrete (non-abstract) members.
Abstract class: is a restricted class that cannot be used to create objects (to access it, it must be inherited from another class). Abstract method: can only be used in an abstract class, and it does not have a body.
Abstract classes, marked by the keyword abstract in the class definition, are typically used to define a base class in the hierarchy. What's special about them, is that you can't create an instance of them - if you try, you will get a compile error.
17 Ιουλ 2024 · Explore the fundamentals of C# abstract classes through clear examples and detailed explanations. Learn how abstract classes facilitate code reusability and polymorphism in object-oriented programming, with practical demonstrations of their usage and implementation in C#.
Use keyword “abstract” for polymorphic methods for which the base class does not define a body If any method in class abstract, class must be abstract
An abstract class in C# provides a blueprint of what its derived classes must implement before they can use it. An abstract class contains abstract members including abstract methods, abstract properties, abstract indexers, and abstract events.
