Please correct me with OOP inheritance

Question

I thought it will call the derived class function because class will give importance to its own function but it is calling base class function please correct me...

class Baseclass { public void fun() { Console.Write("Base class" + " "); } } class Derived1 : Baseclass { new void fun() { Console.Write("Derived1 class" + " "); } } class Derived2 : Derived1 { new void fun() { Console.Write("Derived2 class" + " "); } } class test { static void Main(string[] args) { Derived2 d = new Derived2(); d.fun(); } }

You might want to add a language tag to your question :)

The base class method is called because only the base class method is accessible.

Why aren't the other methods accessible? Let's look at the method in Derived2:

new void fun() { Console.Write("Derived2 class" + " "); }

What is its access modifier? None, so it defaults to private. This means that you can't access this method from test class!

To make it work, simply add a public modifer:

new public void fun() { Console.Write("Derived2 class" + " "); }
