What is an Inheritance in C#?

[- Empty Shell -]

Hi friends,
I am new to the programming language. And I have started with the C# language. I have gone through the Inheritance, but I was unable to understand clearly. There are lot of doubts regarding the inheritance. So can anyone tell me what is an Inheritance in C#? Please help me soon..!!!

you should have enough knowledge about the Classes and Structs before moving to the Inheritance in C#. Classes and Structs are ‘blue-prints’ or templates from which we create objects. An object can be of the following types – Class or Struct . Also an Inheritance is one of the most important characteristic of OOP. Classes are also called reference types Structs are known as value types Classes.

C# supports two types of Inheritance mechanisms

1. Implementation Inheritance
2. Interface Inheritance

Implementation Inheritance - When a class is derived from another class is called as implementation inheritance.
Interface Inheritance - When a type inherits only the signatures of the functions from another type it is interface inheritance.

I think that providing the syntax of both types of implementation will help you, so I provided that :
Following is an syntax example for using Implementation Inheritance :

Class derivedClass:baseClass
{
}

derivedClass is derived from baseClass
The following is an example of Interface Inheritance :

private Class derivedClass:baseClass , InterfaceX , InterfaceY
{
}

derivedClass is now derived from interfaces.

You can use the following example for knowing about the Inheritance in C# :

 using System;

public class ParentClass
{
    public ParentClass()
    {
        Console.WriteLine("Parent Constructor.");
    }

    public void print()
    {
        Console.WriteLine("This is a Parent Class.");
    }
}

public class ChildClass : ParentClass
{
    public ChildClass()
    {
        Console.WriteLine("Child Constructor.");
    }

    public static void Main()
    {
        ChildClass child = new ChildClass();

        child.print();
    }
}
