Serialize Person Object

[Roberto Carriquiry]

I am writeing a webService that needs to recieve a CDO.Person object as a
parameter. but when I run it I have a runtime error.

Cannot serialize member CDO.PersonClass.DataSource of type CDO.IDataSource
because it is an interface

I assume that something is wrong with the serialization of this object.
Does anyone have experience in this subject?

thanks
Rob.-

The error is caused by the fact that the XmlSerializer can't deal
with Interface typed member variables. A webservice ALWAYS uses
XmlSerializer. You have to build the XML yourself and return that, or, if
CDO.Person is serializable using Soap, serialize it to string via a
MemoryStream and return that string, then on the client, deserialize the
object back from the string received.
