System.InvalidCastException: Cannot assign object of type System.Xml.XmlNode[] to an object of type System.String.

Re: System.InvalidC astException: Cannot assign object of type System.Xml.XmlN ode[] to an object of type System.String.

Hi all!

I've found the problem! (but now I want the best solution! :( )

The types for the response parameters of the wsdl, are derivated from
the xsd types, TFloat, TString, ... If I manipulate the response
before deserialize and I replace "tns:TFloat " with "xsd:float" (and
"tns:TStrin g" with "xsd:string ", ....) the response is serialized
correctly by .NET, WHY?

So, I can use a SOAPExtension to replace the types before deserialize,
but it's a little dirty, isn't it!? Is there any better solution?

Thanks in advance,

Marc.
