How to get rid of XmlIgnoreAttribute() when creating proxy dynamically from wsdl?

Question

I am using WebClient to read wsdl from URI.

WebClient client = new WebClient();
Stream wsdlStream = client.OpenRead(wsdlURI);
ServiceDescription wsdl = ServiceDescription.Read(wsdlStream);

Then I set Namespace and CompileUnit and use ServiceDescriptionImporter's GenerateCodeFromCompileUnit method to generate .cs class file.

Then I compile assembly from it and use reflection to call methods. Problem is, that my created .cs file has additional xml attributes. And additional parameters like:

public void Calc(int a, [System.Xml.Serialization.XmlIgnoreAttribute()] bool aSpecified

When I create assembly from this source file, I get methods with more parameters, than they should have. Original method looks like:

public int Calc(int a, int b)

and method in generated source code looks like:

public int Calc(int a, bool aSpecified, int b, bool bSpecified, out int CalcResult, out bool CalcResultSpecified)

How can I get dynamically generated source file without these additional parameters? So I can compile it to assembly and use reflection to call original methods?

Answer 1

The ignored fields are there because the original WSDL specifies some of the parameters as optional but of value types, and the XmlSerializer doesn't support Nullable<T>, so the xxxSpecified parameters allow you to tell it if the value is null or not. Guess you're stuck with them.
