Inheritance: The most important reason to use OOP is to make reusability of Code and eliminate the redundant code. That can be done by one of the OOP concept i.e - -> INHERITANCE. Inheritance supports reusability by defining a class and then use that class again and again.

Inheritance supports a class hierarchy where Base class and Derived class exist, Suppose - -> Animals is the [Base Class] and Dog is the [Derived Class].Derived Class inherits the base class. Also Derived Class can inherits all the member of Base Class.

Let’s Begin our Program!.

Step 1: Open your Visual Studio. By pressing Ctrl +Shift + N you will get your “New Project” Window.

Figure 1: Create Console Application

Step 2: After pressing OK you will get into your Coding Part where you will see three files in Solution Explorer [Properties, References, Program.cs], in which Program.cs file is your main file where you embed all your Inheritance program code.

Figure 2: Solution Explorer

This is your Code for Inheritance Program:

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5. namespace Inheritance_demo21
  6. {
  7. public class Baseclass {
  8. public int datamember;
  9. public void baseclassmethod()
  10. {
  11. Console.WriteLine("This is baseclass method");
  12. Console.WriteLine("-----------------------------------");
  13. }
  14. }
  15. public class DerivedClass : Baseclass
  16. {
  17. public void derivedclassmethod()
  18. {
  19. Console.WriteLine("This is our derivedclassmethod");
  20. }
  21. }
  22. class Program
  23. {
  24. static void Main(string[] args)
  25. {
  26. //create base class object
  27. Baseclass bc = new Baseclass();
  28. bc.datamember=1;
  29. bc.baseclassmethod();
  31. //create derived class object
  33. DerivedClass dc = new DerivedClass();
  34. dc.datamember = 2;
  35. dc.derivedclassmethod();
  36. dc.baseclassmethod();
  37. Console.ReadKey();
  39. }
  40. }
  41. }
