Inheritance is a mechanism for code reuse where a derived (or sub) class is based on a base (or super) class thereby having access to all of the base class' members. The Person type we created earlier implicitly derived (inherited) from System.Object. Now, we will create a new class that explicitly inherits from Person.
In Solution Explorer, ensure that the Ch06_PacktLibrary project has the focus. Next, from the Project menu, choose Add Class… or press Shift + Alt + C. Name the class Employee.
Modify its code as follows:
using System;
namespace Packt.CS6
{
public class Employee : Person
{
}
}Add a new console application named Ch07_InheritanceApp.
Add a reference to the Ch06_PacktLibrary assembly.
Modify the Program.cs file to import the Packt.CS6 namespace and add statements to the Main method to create an instance of the Employee class:
using Packt.CS6;
using System;
using static System.Console;
namespace Ch07_InheritanceApp
{
class Program
{
...
