XmlSerialization serializing with xsi:type specified

[pfrisbie]

I am developing a Web Services interface with C# and our partner is
using Java (Axis 1.1). They require me to include xsi:types in the
SOAP Messages I send them. For example:

<Partner xmlns="urn:partner.xxxxx.com">
<RequestID>239</RequestID>
<TimeStamp>2006-03-06T17:10:51.4662331-06:00</TimeStamp>
<Subject xmlns:ns1="urn:partnermapping.xxxxxx.com"
xsi:type="ns1:PartnerMapping">
<AccountID>98401</AccountID>
</Subject>
</Partner>

Is this possible with XmlSerialization? I searched all over and cannot
find any examples of this. How do I specify it using .Net
XmlSerialization?

Thanks,

pfrisbie

I had the opposite problem. The web services were not sending me the
xsi:type that I required to deserialize properly a certain element.

What i did was a SoapExtension that searched for the element and if the
xsi:type was not present it would add it manually manipulating the
XmlDocument.

David, you are right, a SOAP Extension would work. I'm wondering if
your WebService required an xsi:type then that suggests that
XmlSerialization is aware of xsi:types so it should be able to
deserialize them as well. Is there are attribute or something in your
classes that looks like it sets the xsi:type? Thanks -- Pat.

My code required an xsi:type because that element was declared as:

[System.Xml.Serialization.XmlElementAttribute(Names pace="http://the.namespace/")]
public object theUnknownElement;

It was an object because each service provided a different type. I have
several SoapHttpClientProtocol that deal with each service:

[System.Xml.Serialization.XmlInclude( typeof( OneSpecificType))]
public class GeneratedStub:
System.Web.Services.Protocols.SoapHttpClientProtoc ol
{...}

The services did not provide an xsi:type because they provided always
the same type. It was me who had to be flexible.

My testing Web Service also had [XmlInclude( typeof(
OneSpecificType))].

You could also examine their WSDL and hack it to turn Subject into a
anyType or Choice. Look also abstract elements (
http://www.w3.org/TR/xmlschema-0/#abstract ).
Generate code from the hacked WSDL and compare with what you have.
If you don't have Java's WSDL, try to generate one from your client.
