Calling derived class method by the base type reference variable in C#

Program

using System;

namespace Polymorphism

{

    class ReferingDerivedObjects

    {

        public class Person

        {

            public void getPerson()

            {

                Console.WriteLine("Get Details about Person...");

            }

        }

        class Employee: Person

        {

            public void getEmployee()

            {

                Console.WriteLine("Get Details about Employee");

            }

        }

        static void Main(string[] args)

        {

            Person p;

            p = new Person();

            p.getPerson();

            p = new Employee();

            p.getPerson();

            //Parent type can't access derived type method

            //p.getEmployee(); //will not work...

            Employee e = new Employee();

            e.getPerson();

            e.getEmployee();

            Console.ReadKey();

        }

    }

}

Output

Get Details about Person...//when base ref.var referring base object

Get Details about Person...//when base ref.var referring derived object

Get Details about Person...//when derived ref.var referring derived object

Get Details about Employee//when derived ref.var referring derived object
