Is it possible to extend XSD generated classes with methods and properties?
I have a schema with around 200 complexTypes. I'd like to provide methods
for many of them. My first approach was use XSD.exe to generate classes
for the complexTypes (in the 'commonNamespace' namespace), to derive a new
CS class from the XSD generated class, and to provide the methods there.
However, that doesn't serialize. Here's a copy of my subclass :
namespace commonNamespace {
[System.Xml.Serialization.XmlTypeAttribute( Namespace="myURI",
TypeName="Type_t")]
public class myType : Type_t // Type_t is a class generated by XSD.exe in
the commonNamespace namespace
{
void doIt()
{
// execute my business logic
}
}
}
I have a root element in my schema that has a Type_t element in it. If my
C# code constructs a myType, populates the relevant fields, and then
serializes it, I get
System.InvalidOperationException on my XmlSerializer.Serialize() call. If I
change my C# to populate a Type_t instead of a myType, then it works.
Is there something I can do without hand-editing the generated C# code to
make this work? It doesn't appear that you can pass XmlIncludeAttributes
to the XmlAttributesOverrides.Add() method.
Thanks in advance,
Howard
