Introduction

In this lesson, you will learn inheritance in C# for beginners. Inheritance allows one class to reuse properties and methods of another class.

What is Inheritance?

Inheritance is a feature of OOP where one class (child class) inherits from another class (parent class).

Basic Example

class Animal
{
    public void Eat()
    {
        Console.WriteLine("Animal is eating");
    }
}

class Dog : Animal
{
}

class Program
{
    static void Main()
    {
        Dog d = new Dog();
        d.Eat();
    }
}

Types of Inheritance in C#

Single Inheritance

One class inherits from one parent class.

Multilevel Inheritance

A class inherits from a class which is already inherited.

Hierarchical Inheritance

Multiple classes inherit from one parent class.

Benefits of Inheritance

• Code reuse
• Reduces duplication
• Improves maintainability

Real-World Example

• Animal → Dog, Cat
• Vehicle → Car, Bike

Key Points

• Inheritance promotes code reuse
• Child class can access parent class methods
• Improves code structure
