How to write custom serialization method in C# web service

[psy000]

Hi,

I have a C# web service client that talks to a JAVA application sever.
I use AXIS to generate the WSDL file, use wsdl.exe to generate proxy
stub c# code. When I try to use c# client connect to application
server, I did not get the result in the C# client side, I used a soap
monitor to look at the SOAP messages that were exchanged, I can see
server returned a correct SOAP message, but the C# client failed to
deserialize the XML result back to the C# object.

I wonder if there is a way to write a custom XML deserializer to
populate the result back to C# object. The serialization part seemed to
be ok.

The following is the proxy code generated by wsdl.exe:

public class CommandServerSe rvice :
System.Web.Serv ices.Protocols. SoapHttpClientP rotocol {

/// <remarks/>
public CommandServerSe rvice() {
this.Url = "http://localhost:7001/services/CommandServer";
}

/// <remarks/>
[System.Web.Serv ices.Protocols. SoapDocumentMet hodAttribute("" ,
Use=System.Web. Services.Descri ption.SoapBindi ngUse.Literal,
ParameterStyle= System.Web.Serv ices.Protocols. SoapParameterSt yle.Bare)]
[return:
System.Xml.Seri alization.XmlEl ementAttribute( "executeCommand Return",
Namespace="http ://webservice.foo. com")]
public TargetableComma nd
executeCommand([System.Xml.Seri alization.XmlEl ementAttribute( Namespace="http ://webservice.foo. com")]
string in0,
[System.Xml.Seri alization.XmlEl ementAttribute( Namespace="http ://webservice.foo. com")]
TargetCommand in1) {
object[] results = this.Invoke("ex ecuteCommand", new object[] {
in0,
in1});
return ((TargetCommand )(results[0]));
}

....

}

The elements of "results[0]" are null.I used "Document/Literal" style
in wsdl document. I can get the result[0] with correct values populated
when I use "RP C encoding" style.

The generated proxy code does not tell me how System.Xml.Seri alization
is called to handle serialization/deserialization , it seems that .Net
handles it automatically. I wonder how I can overwrite this behavoir by
supplying a custom serialization/deserialization method to populate the
result[0] with returning values. The following is the XML document
returned by the server:

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelo pe
xmlns:soapenv=" http://schemas.xmlsoap .org/soap/envelope/"
xmlns:xsd="http ://www.w3.org/2001/XMLSchema"xmlns :xsi="http://www.w3.org/2001/XMLSchema-instance">

<usingTransient Session
xsi:type="xsd:b oolean">false</usingTransientS ession>
</executeCommandR eturn>
</soapenv:Body>
</soapenv:Envelop e>

The values returned by the server are in the message, but the client
failed to deserialize the values into result[0], which is
"TargetComm and" objec.

I am new to C#, any advice is appricated.

Thanks
