Hi

Pass your objects as an array instead - that will do the trick

Hi,

The XmlSerializer needs to know the types that it will encounter in your
collection. The collection itself is fine, but you need to add an
XmlInclude attribute to your method call, one for each type that the
serializer will encounter when it goes to serialize the collection. The
data in the objects in the collection will have to be serializable types.

On the server side, the web service will need to expect an array of inputs
or a custom collection definition. Generally, one should build the calling
interface from a description of the server's interface. On the wire there
is little difference between a collection and an array, so usually you can
use a collection as a parameter anywhere you would expect to see an array,
and vice versa.
