Learn C# OOP to write cleaner, modular, and scalable code by understanding classes in C#, working with objects in C#, and applying principles like data hiding, encapsulation, and inheritance.

Become a C# Programmer

This module provides an in-depth exploration of C# OOP (object-oriented programming), focusing on writing cleaner, more modular, and scalable code. We'll begin by covering the basics of classes in C# and objects in C# and progress toward advanced OOP concepts such as encapsulation, data hiding in C#, inheritance in C#, and polymorphism. Throughout, we’ll see how C# supports these OOP principles with its unique features to enhance development efficiency.

Object-Oriented Programming in C#

## Declaration

In C#, we declare classes in the following way:

class ClassName // Class name
{ 

    /* All member variables
    and methods */

}

The keyword `class` tells the compiler that we are creating our custom class. All the members of the class will be defined within the class scope, i.e.,  inside the curly brackets, `{...}`.


## Creating a Class Object
The name of the class, `ClassName`, will be used to create an instance/object of the class in our `Main()` method. We can create an object of a class by using the `new` keyword:
