What is polymorphism and inheritance in C#?

What is polymorphism and inheritance in C#?

Polymorphism means “many forms”, and it occurs when we have many classes that are related to each other by inheritance. Like we specified in the previous chapter; Inheritance lets us inherit fields and methods from another class. Polymorphism uses those methods to perform different tasks.

Can polymorphism work with out inheritance in C#?

inheritance and polymorphism are independent but related entities – it is possible to have one without the other. if we use a language that requires variables to have a specific type ( c++ , c# , java ) then we might believe that these concepts are linked.

What is polymorphism C# example?

Method overloading is an example of Static Polymorphism. In overloading, the method / function has a same name but different signatures. Here C# compiler checks the number of parameters passed and the type of parameter and make the decision of which method to call and it throw an error if no matching method is found.

What is polymorphism with real time example?

Real-life Illustration: Polymorphism Like a man at the same time is a father, a husband, an employee. So the same person possesses different behavior in different situations. This is called polymorphism. Polymorphism is considered one of the important features of Object-Oriented Programming.

How inheritance is used in C# with example?

C# Single Level Inheritance Example: Inheriting Methods

  1. using System;
  2. public class Animal.
  3. {
  4. public void eat() { Console.WriteLine(“Eating…”); }
  5. }
  6. public class Dog: Animal.
  7. {
  8. public void bark() { Console.WriteLine(“Barking…”); }

How polymorphism is implemented in C#?

Compile time polymorphism is achieved by method overloading and operator overloading in C#. It is also known as static binding or early binding. Runtime polymorphism in achieved by method overriding which is also known as dynamic binding or late binding.

What is inheritance in C# with example?

This tutorial introduces you to inheritance in C#. Inheritance is a feature of object-oriented programming languages that allows you to define a base class that provides specific functionality (data and behavior) and to define derived classes that either inherit or override that functionality.

How does polymorphism work in C#?

In C#, polymorphism is implemented through inheritance and the use of the keyword “virtual”. Derived classes inherit the base class members, except constructors, based on their accessibility levels. An example of polymorphism is an employee base class, which includes all the basic details about employees.

Is inheritance a type of polymorphism?

The basic difference between inheritance and polymorphism is that inheritance allows the already existing code to be reused again in a program, and polymorphism provides a mechanism to dynamically decide what form of a function to be invoked.
