An overview of Object Oriented Programming in C#.

This slide shows basic object oriented programming concepts used in c#.

1.  Introduction to Object-Oriented Programming in C#

2. What is Object-Oriented Programming (OOP)? OOP is a programming paradigm that organizes software design around "objects" rather than functions and logic. An object is an instance of a class, which encapsulates data (attributes) and behavior (methods).

3. Why OOP? Modularity : Code is organized into reusable components (classes and objects). Abstraction : Simplifies complex systems by modeling real-world entities. Encapsulation : Protects data by restricting access to it. Inheritance : Promotes code reuse by allowing new classes to inherit properties and methods from existing ones. Polymorphism : Enables objects to be treated as instances of their parent class, allowing for flexible and dynamic code.

4. OOP in C# C# is a modern, object-oriented language developed by Microsoft. It fully supports OOP principles, making it ideal for building scalable and maintainable applications. C# is widely used in desktop, web, and mobile development, as well as in game development with Unity.

5. What You Will Learn How to define classes and create objects in C#. Implementing inheritance, polymorphism, encapsulation, and abstraction. Best practices for designing object-oriented applications in C#.

6. Key Concepts in C# OOP Classes and Objects : The building blocks of OOP in C#. Inheritance : Creating new classes from existing ones. Polymorphism : Using methods in different ways depending on the object type. Encapsulation : Controlling access to data using access modifiers like public, private, and protected. Abstraction : Hiding complex implementation details and exposing only necessary features.

7. 1. Classes and Objects Class : A blueprint or template for creating objects. It defines the properties (attributes) and behaviors (methods) that the objects created from the class will have . Object : An instance of a class. It represents a real-world entity with its own state (data) and behavior (methods).

8. 2. Encapsulation Encapsulation is the concept of bundling data (attributes) and methods (functions) that operate on the data into a single unit (a class). It also involves restricting direct access to some of an object's components, which is achieved using  access modifiers  like private, public, and protected.

9. 3. Inheritance Inheritance allows a class (child/derived class) to inherit properties and methods from another class (parent/base class). Promotes  code reusability  and establishes a relationship between classes.

10. 4. Polymorphism Polymorphism means "many forms." It allows objects of different classes to be treated as objects of a common base class. Achieved through  method overriding  (runtime polymorphism) and  method overloading  (compile-time polymorphism).

11. 5. Abstraction Abstraction is the process of hiding complex implementation details and exposing only the necessary features of an object. Achieved using  abstract classes  and  interfaces .
