First, can I ask you to change your posting name from Borland ?
Now, to the matter in hand.
Don't forget that, in C#, static methods cannot be virtual. Therefore,
you have to redlclare the method in each and every derived class but
simply calling the static method on the base type will only call that
method, not the derived one.
However, here is a simple example fo how to create a factory class that
will call the correct method, depending on the type passed in.
