rich type

[Francois Malgreve]

Hi all,

I would like to know what kind of rich type (i mean complex type) a
webservice can return.
I have seen some example showing that a webservice can return a DataSet
(does it just call DataSet.GetXml()?).
How can I know is one type or an other type will be supported by webservice?
Can a webservice also return a DataTable or a DataView? In fact I would like
that my webservice return a dataview but i am not sure of how to do so. It
seems difficult to know what type are supported by webservice and also what
is the serialization mechanism used by webservice

Tx in advance

Essentially.

You can add support for any type.

No, not in 1.1. In 2.0 IIRC a DataTable can be returned.

A dataview doesnt really contain any data. Why not just fill into another
Dataset and return then?

This is all listed in MSDN quite plainly.
