xml deserialization override namespace

xml deserialization override namespace

I'm parsing xml based on an xsd using the generated c# class. The provider
of the XML updated the schema but some responses I am getting do not use
the new schema - the main thing that changed was the namespace.
So the xmlns= tag at the root level of the XML is incorrect for the
generated c# class to deserialize and I get an exception saying that the
xmlns= is unexpected. If I manually change the namespace to match that of
the schema the xml deserializes just fine as I would expect.
So I embarked on a journey to override the namespace. Here's my code
attempt: * This compiles and runs but yields the standard error that the
tag is unexpected and that there is an error in the XML
If I uncomment the attrs.Xmlns = true;
Then at the time of creation of the serializer (two lines down) I get an
operation exception that says:
System.InvalidOperationException was unhandled
Message="There was an error reflecting type 'MessageType'."

SO - how do I make this work - without changing the generated class
because eventually data will come in with the right namespace - and
without changing the XML received? How can I make the override work?
* code *
var attrs = new XmlAttributes();
/* Create an XmlRootAttribute to override the XmlRoot in-line attr.
The override will use no namespace. */
var attr = new XmlRootAttribute("Message");
// attr.ElementName = "Message";
attr.Namespace = "http://www.ncpdp.org/schema/SCRIPT";
// set the XmlRoot on the XmlAttributes collection.
attrs.XmlRoot = attr;
// Create the XmlAttributeOverrides object.
var o = new XmlAttributeOverrides();
/* Map the attributes collection to the thing being
overriden (the class). */
// attrs.Xmlns = true;
o.Add(typeof(MessageType), attrs);
//
XmlSerializer serr = new XmlSerializer(typeof(MessageType),o);
// XmlSerializer sexx = new XmlSerializer(
// deserialize
try
{
rsp = (MessageType)serr.Deserialize(reader);
XmlSerializer serx = new XmlSerializer(typeof(MessageType));
TextWriter w1 = new StreamWriter(@"c:\ssresp.xml");
serx.Serialize(w1, rsp);
w1.Close();
string retFile;

// UpdatePharmacyItem(rsp, "PhoneNumbers", "Delete",

retFile = ParseResponse(rsp);

string responseFromServer = reader.ReadToEnd();
StreamWriter SW;
SW = File.CreateText(@"C:\raw.txt");
SW.WriteLine(responseFromServer);
SW.Close();

return;
