If you want to create an object that supports run-time addition of properties, and you can use C# 4.0, you can use System.Dynamic.ExpandoObject

dynamic myObject = new ExpandoObject();
myObject.AnswerToUltimateQuestionOfTheUniverse = 42;

EDIT: I see that you have now explictly mentioned C# 3.0. This is no longer applicable.

please see again , I have mentioned 3.5 not 3.0. I think we can do this by Dictionary or Hash table but how to achieve exact? – Red Swan Aug 20 '10 at 09:13

Attach additional responsibilities to an object dynamically with the Decorator Pattern: http://www.dofactory.com/Patterns/PatternDecorator.aspx
