COM and XMLSerialiser

[Newbie]

Hi,
I have a COM object which I would like to serialize so
that I can pass this object as a parameter through my
ASP.Net web service. Is this possible?

If not what is the best approach to take here?

I'm not yet in a position to convert my com object into
a .Net class due to the number of other COM based
processes that this will impact on.

Any guidance appreciated.
Thanks in advance
