It's really amazing that this works at all.

Consider that you're serializing your objects into XML for some other piece
of code to deserialize. You aren't giving that client code much information
about what you're sending. Have you looked at the generated WSDL? The Val
field is declared:

<s:element minOccurs="0" maxOccurs="1" name="Val" />

This only works at all because the type information will be included in the
XML for the primitive types:

<Val xsi:type="xsd:dateTime">2007-07-19T15:39:52.4875-04:00</Val>

Which xsi:type should it use for Field[][]?

BTW, it _does_ work if you wrap the Field[][]. Furthermore, if you don't
want the two to be different, then you should always use the wrapped
version. Have your webmethod return WrappedArrayOfArrayOfField. That will
return something like this:

<Val xsi:type="FieldWrapper">
<Wrapped>
<ArrayOfField>
<Field>
<Name>name1</Name>
<Val xsi:type="xsd:int">1</Val>
</Field>
<Field>
<Name>name2</Name>
<Val xsi:type="xsd:string">abc</Val>
</Field>
</ArrayOfField>
...

That's the part that I don't get; I have looked at the WSDL (far too
many times!), and I can see the overall result node:

<s:element name="GetTasksResponse">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1"
name="GetTasksResult"
type="tns:ArrayOfArrayOfField" />
</s:sequence>
</s:complexType>
</s:element>

So, in answer to your question:

Which xsi:type should it use for Field[][]?

I would have thought tns:ArrayOfArrayOfField would be the type it
would serialize as. There is a node with that name in the WSDL
already, so I don't understand why it can't utilise that?

I've tried putting a string[][] into Val, and that blows up too, so it
seems that it's just a problem putting a multi-dimensional (well,
jagged) array into the Val.

In fact, we just tried returning a jagged array from a web method that
returns one System.object, tried returning string[][], and that
doesn't work either, so that seems to confirm that you just can't
return a jagged array as System.object. I'm intrigued as to why that
is the case though.

Cheers,

Paul
