Run Time PolyMorphism Example---2 For Beginner??????

creating an object of Derived class DerivedClass and storing its reference in the reference variable bc of type BaseClass. This is valid in C#.

class Program
    {     
        static void Main(string[] args)
        { 
         Baseclass bc;
         bc = new Baseclass();
         bc.Show();
         bc = new DerivedClass();
         bc.Show(); 
         Console.ReadLine();
  
        }
   
    }

    class Baseclass
    {
        public void Show()
        {
            System.Console.WriteLine("Baseclass::Show");
        }
    }

    class DerivedClass : Baseclass
    {
        new public void Show()
        {
            System.Console.WriteLine("DerivedClass::Show");
        }
    }

Output


Baseclass::Show
Baseclass::Show

bc is a reference of type Baseclass, the function Show() of class Baseclass will be invoked, no matter whom bc refers to.
