Override namespace in XML for deserialization with generated class

[ThaneHubbell]

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'."
Source="System.Xml"

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", "Update", "9314421118", "PH");
// UpdatePharmacyItem(rsp, "PhoneNumbers", "Update", "9316256234", "HO");
// UpdatePharmacyItem(rsp, "PhoneNumbers", "Delete", "", "FX");
retFile = ParseResponse(rsp);
}
catch (Exception e)
{
reader.BaseStream.Position = 0;
string responseFromServer = reader.ReadToEnd();
StreamWriter SW;
SW = File.CreateText(@"C:\raw.txt");
SW.WriteLine(responseFromServer);
SW.Close();
reader.Close();
return;
}
}
