How can I inherit attributes?

[Michael]

Hi,

I create an abstract baseclass with the attribute [Serializeable].
I want that all classes that inherit thate baseclass also iherhit
[Serializeable].
How can I do that?. It seems to me that I have to write the attribute to
each class manualy.
Tryed in .NET 1.0, 1.1 und 2.0.

Thanks for a fast answere
Michael
