Vulpes · Answer

If a method property indexer or event is declared to be virtual then it means that it can be overridden in a derived class which wants to provide a specialized implementation. The signature return type and access modifier of a virtual method and methods which override it must be the same. When a virtual member is accessed through a variable of the base class type the actual type of the object determines which version of the method to call. For example: using System; class Base { public virtual void MyMethod() { Console.WriteLine(Hello from Base class); } } class Derived : Base { public override void MyMethod() { Console.WriteLine(Hello from Derived class); } } class Test { static void Main() { Base b = new Base(); // b refers to a Base object b.MyMethod(); // calls Base.MyMethod b = new Derived(); // b refers to a Derived object b.MyMethod(); // calls Derived.MyMethod Console.ReadKey(); } }

The virtual modifier tells the compiler that when any class derived from class A is used an override method should be called. refer this in easy way and understandable http://www.dotnetperls.com/virtual http://www.programcall.com/26/csnet/virtual-methods-in-csnet-with-example.aspx
