Hello!

i am desparetely trying to consume a PHP Webservice in VB.NET 2005.
I can add the webreference, compile without errors and see the methods of 
the webservice.
But on runtime it tells me {"There is an error in XML document (6, 62)."}.
Inner Exception:
{"Cannot assign object of type System.Xml.XmlNode[] to an object of type 
System.String."}

Envelope that comes from the webservice:
_________________________________________

<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope 
xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/'

            </item>
         </details>
      </ns1:getArticleDetailsResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>


Relevant part of WSDL (no complex types because i did not get them to import 
at all in .NET):
__________________________
   <message name="getArticleDetailsRequest">
      <part name="artId" type="xsd:int"/>
   </message>

   <message name="getArticleDetailsResponse">
      <part name="details" type="xsd:ArrayOfString"/>
   </message>
____________

Strange: I defined ArrayOfString, but .NET expects just string.

How can I get that to run?
Thank you!

Best Regards,
Dirk

Please post the WSDL, so we can see _how_ you defined ArrayOfString.

Also, why did you define it in the "xsd" namespace? That's not your 
namespace, so you don't get to change it.

Also, it doesn't look like the service is sending ArrayOfString, unless 
ArrayOfString is the same thing as ns2:Map.

thanks for John's input.

Hi Dirk,

I agree with John that the problem is likely caused by the type mismatching 
between the generated webservice client proxy and the corresponding object 
member in the SOAP response message. As the following line indicates:

=========
{"Cannot assign object of type System.Xml.XmlNode[] to an object of type 
System.String."}
=========

the webservice proxy class contains a string member while the SOAP response 
message return an node list(array), at least the .net webservice 
deserializer deserialize it into a nodelist which cause the type 
mismatching problem.

Please feel free to post some further info(like WSDL document) so that we 
can have a look and perform some test on it.

Sincerely,

Steven Cheng
