XmlSerializer.Serialize Stripping the <xml> tag

I am trying to get communicate to a payment processor. When I use

XmlSerializer.Serialize

on my object I get

<?xml version=\"1.0\" encoding=\"utf-16\"?>
<txn xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">
<ssl_merchant_id>xxxxxx</ssl_merchant_id>
<ssl_user_id>xxxxxx</ssl_user_id>
<ssl_pin>xxxxxx</ssl_pin>
<ssl_test_mode>True</ssl_test_mode>
<ssl_transaction_type>ccavsonly</ssl_transaction_type>
<ssl_card_number>4111111111111111</ssl_card_number>
<ssl_exp_date>0612</ssl_exp_date>
<ssl_avs_address>101 Main St.</ssl_avs_address>
<ssl_avs_zip>90210</ssl_avs_zip>
</txn>


Prior to using that method, I manually built the XML for testing and this worked:

<txn>
<ssl_merchant_id>xxxxxx</ssl_merchant_id>
<ssl_user_id>xxxxxx</ssl_user_id>
<ssl_pin>xxxxxx</ssl_pin>
<ssl_test_mode>True</ssl_test_mode>
<ssl_transaction_type>ccavsonly</ssl_transaction_type>
<ssl_card_number>4111111111111111</ssl_card_number>
<ssl_exp_date>0612</ssl_exp_date>
<ssl_avs_address>101 Main St.</ssl_avs_address>
<ssl_avs_zip>90210</ssl_avs_zip>
</txn>


How would I go about stripping out the
<?xml version=\"1.0\" encoding=\"utf-16\"?>
and
xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">
from the XML or not have the serializer generate it to begin with?

My object looks like:

[XmlRoot(ElementName="txn")]
public class AvsTransmission
{
[XmlElement]
public string ssl_merchant_id { get; set; }
[XmlElement]
public string ssl_user_id { get; set; }
[XmlElement]
public string ssl_pin { get; set; }
[XmlElement]
public string ssl_test_mode { get; set; }
[XmlElement]
public string ssl_transaction_type { get; set; }
[XmlElement]
public string ssl_card_number { get; set; }
[XmlElement]
public string ssl_exp_date { get; set; }
[XmlElement]
public string ssl_avs_address { get; set; }
[XmlElement]
public string ssl_avs_zip { get; set; }
}

Answer

My first answer was only half of the problem, you also have to remove the declaration as has been mentioned.

Here is an example:

XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;

MemoryStream ms = new MemoryStream();
XmlWriter writer = XmlWriter.Create(ms, settings);

XmlSerializerNamespaces names = new XmlSerializerNamespaces();
names.Add("", "");

XmlSerializer cs = new XmlSerializer(typeof(Cat));

cs.Serialize(writer, new Cat { Lives = 9 }, names);

ms.Flush();
ms.Seek(0, SeekOrigin.Begin);
StreamReader sr = new StreamReader(ms);
var xml = sr.ReadToEnd();

The string xml now contains:

<cat><Lives>9</Lives></cat>
