Abstraction in C#
Abstraction in C# Abstraction is a fundamental concept in object-oriented programming (OOP) that involves focusing on the essential features of an object while hiding its implementation details. In C#, abstraction is achieved through abstract classes and interfaces. Abstract Classes * Declaration: abstract class Shape { public abstract void Draw(); } * Key Points: * Can contain both abstract and concrete methods. * Cannot be instantiated directly. * Derived classes must implement all abstract methods. * Can contain fields, properties, and constructors. Interfaces * Declaration: interface IDrawable { void Draw(); } * Key Points: * Contain only abstract methods and properties. * Cannot contain fields, constructors, or static members. * Can be inherited by multiple classes. * Provide a contract that classes mus...
