Transform an object in a XDocument with xmlns

Question

Actually I transform an object to a XDocument with this function

public XDocument ToXDocument()
{
         var xDocSerialized = new XDocument();
         using (var writer = xDocSerialized.CreateWriter())
         {
                  var serializer = new XmlSerializer(this.GetType(), new XmlRootAttribute("PrintRequest"));
                  serializer.Serialize(writer, this);
         }
         return xDocSerialized;
}

It is possible to add a xmlns in the process ?

I found this page, but it means cloning all XDocument again...

Answer 1

Try this:

var serializer = new XmlSerializer( this.GetType(), null, null, new XmlRootAttribute( "PrintRequest" ), "my namespace..." );

Hi @Olivier Voutat ,
You can also change the namespace of the root element via following code:

XNamespace xmlns = "your XNamespace string";  
XDocument.Root.Name = xmlns + XDocument.Root.Name.LocalName;  

More details please refer to this thread.
