Serialize XML with Qualified or Prefixed Root Element

I'm trying to serialize/deserialize the XML for an RSS 1.0 Feed (i.e. RDF)
and the root element, as required by the standard, looks like this:

<rdf:RDF ...>

</rdf:RDF>

However, I've tried everything using XmlRootAttribute, XmlTypeAttribute,
XmlSerializerNamespacesAttribute, etc, and nothing will serialize to or
deserialize from this root element format.

I can get child elements to be prefixed by using the XmlElementAttribute and
a namespace, but cannot achieve this with the root element, which is required
to serialize and deserialize RDF documents.

How do you make this work?

re: Serialize XML with Qualified or Prefixed Root Element

Ok, I'm using XmlSerializer to serialize and deserialize an object to Xml.
Primarily, I am attempting to use the XmlSerializer.Deserialize method to
deserialize an RSS 1.0 (RDF) feed directly into a .NET object.

However, by the specification of the RSS 1.0 (RDF) format, the root element
of the Xml should be <rdf:RDF>.

I have tried everything with the .NET framework to create a .NET class that
will serialize or deserialize to Xml that can begins with a prefixed or
qualified root element such as <rdf:RDF>.

I can use the XmlElement tag to generate Xml elements with a prefix,
however, I cannot make this work for the root element. No combination of
XmlRootAttribute, XmlTypeAttribute, etc will serialize or deserialize Xml
files with a prefixed or qualified root element.

[XmlType("testResults",
Namespace = "urn:testResults.namespace.com")]
public class TestResults
{
}

Answer:

1. Instantiate an XmlSerializerNamespaces object.
2. Use the Add method of the object to add all (prefix, namespace) pairs
needed.
3. Include the object as the third parameter in the Serialize method of the
XMLSerializer object.
