Polymorphism - Programming Code

Simple Programming Codes 

Polymorphism - Programming Code :-

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace polymorphism

{

    class Employee

    {

        public string FirstName = "FN";

        public string LastName = "LN";

        public virtual void PrintFullName()

        {

            Console.WriteLine(FirstName + " " + LastName);

        }

    }

    class FullTimeEmployee : Employee

    {

        public override void PrintFullName()

        {

            Console.WriteLine(FirstName + " " + LastName + "-Full Time Employee");

        }

    }

    class PartTimeEmployee : Employee

    {

        public override void PrintFullName()

        {

            Console.WriteLine(FirstName + " " + LastName + "-Part Time Employee");

        }

    }

    class TemporaryEmployee : Employee

    {

    }

    class Program

    {

        static void Main(string[] args)

        {

            Employee[] emp = new Employee[4];

            emp[0] = new Employee();

            emp[1] = new FullTimeEmployee();

            emp[2] = new PartTimeEmployee();

            emp[3] = new TemporaryEmployee();

            foreach (Employee e in emp)

            {

                e.PrintFullName();

            }

        }

    }

}

then output will be like :
FN LN
FN LN - Full Time Employee

FN LN - Part Time Employee

FN LN


*** This is very simple codenext i will post again Polymorphism Program code,            Thank you... ***
