Object creation fundamental [Resolved]

Hi
1. The object is of derived class as you have written new DerivedClass();
you can call the

baseClass.GetType()

method to see it.
This object has been type casted to that of a base class which will restrict the use to member/method of base class only.
lets say i have two classes as follows

public class MyBaseClass

    {

        public int BaseID { get; set; }

    }

    public class DerivedClass:MyBaseClass

    {

        public int DerivedID { get; set; }

    }

and i am writing something like

MyBaseClass b = new DerivedClass { BaseID = 10, DerivedID = 20 };

Console.WriteLine(b.BaseID);

here i will only get BaseID, I can again typecast the same object to get DerivedID

DerivedClass d = b as DerivedClass;

Console.WriteLine(d.DerivedID);

Hi

By assigning a derived class instance to that of a base one ,will restrict the access of instance to the part that came from base calss to the derived.

Thanks for ur reply...

From the above, i have a few questions:-
(1) The object is of derived class or base class ?
(2) And it is casted to which type...?

I am little but confused regarding this casting...?
I have followed your link but it couldn't clear my doubts......

Thanks and Regards

Hi ndebata......

excellent description of the scenario....

So, we cannot call derived class members directly, first we have to typecast it to derived class then we can call it ?
