Overriding (C# and JavaScript Cross Reference Guide)

General Info: Method Overriding

Where you define or implement a virtual method in a parent class and then replace it in a descendant class.

When you decide to declare a method as virtual, you are giving permission to derived classes to extend and override the method with their own implementation. You can have the extended method call the parent method's code too.

In most OO languages you can also choose to hide a parent method. When you introduce a new implementation of the same named method with the same signature without overriding, you are hiding the parent method.

C#:   virtual, override In C#, you specify a virtual method with the virtual keyword in a parent class and extend (or replace) it in a descendant class using the override keyword. Use the base keyword in the descendant method to execute the code in the parent method, i.e. base.SomeMethod(). Syntax Example: class Robot { public virtual void Speak() { } } class Cyborg:Robot { public override void Speak() { } }  C# Overriding (virtual, override)
