Inheritance in C#

December 27, 2021 C#

In this post, you will learn how to work with inheritance so that you can use that same knowledge and thus evolve.

inheritance is a mechanism by which a class (subclass) can extend another class (superclass) to take advantage of its possible variables (attributes) and its behavior (methods);
a class can only inherit from only one class;
protected boils down to the possibility of access only within the class itself or within a class derived from it.

using System;

namespace Base {
  class Inheritance {
    public void Run() {
      var person = new Son();
      person.Information();
      person.FavoriteFood();

      /*
        Name: Nelson Silva
        Age: 25
        My favorite food is seafood rice.
      */
    }
  }

  class Dad {
    protected string lastName = "Silva";

    public void FavoriteFood() {
      Console.WriteLine("My favorite food is seafood rice.");
    }
  }

  class Son : Dad {
    private string firstName = "Nelson";
    private int age = 25;

    public void Information() {
      Console.WriteLine($"Name: {firstName} {lastName}");
      Console.WriteLine($"Age: {age}");
    }
  }
}
