By overloading a method you get an alternative for that method. By shadowing a method you simply hide the other version of the method and it becomes inaccessable.

Overloading can occur with in the same class too, for eg:
//Example for overloading public int addnumbers(int a, int b) { return a+b; } public int addnumbers(int a, int b, int c) { return a+b+c; }Method Hiding can happen only when inheritance comes to picturepublic class Maths { public Maths() { //.Ctor } public int addnumbers(int a, int b) { return a+b; } } public class TwoMaths : Maths { public TwoMaths() { //.Ctor } // This method hides the base class's method // if you create a object for TwoMaths class, the base class's // addnumber method cannot be called unless until you explicitly //cast TwoMaths' object in to Maths object public int addnumbers(int a, int b) { return a+b; } } -

Thanks now i got to know what Shadowing is. When ever i post some question in this forum by expecting this type of answers but i am not receiving exact response from the forum members. They are asking to read from the sites and books etc., they are correct. Atleast they are showing me the way but after reading from the book only i am posting my questions here. Some times i got struck (hang-up) with some topics may be they are very simple. as i am new to this technology..i need simple explaination like what u dropped here for shadowing.... Thanks once again for ur response. Rahi

Thanks once again, Rahi
