Problems making an XML Soap Header

I need to access a webservice developed by another company. This webservice requires a correctly formatted Header for authentication. A sample that they provided is attached.

I have spent hours researchign how to make soap headers, and I am almost there, however the soap header I create has an extra layer in it. Which is making it invalid. I have tried everything to "not" have this extra layer, but I cannot work it out.

Can someone please put me out of my misery.

Below is the code I use to create the header. This appears to be correct, but this issues is the XML we are sending.

using (new OperationContextScope(_svc.InnerChannel))
                {
                    var doc = new XmlDocument();

                    var rootNode = doc.CreateElement("HTNGHeader");

                    doc.AppendChild(rootNode);

                    var from = doc.CreateElement("From");

                    var systemId = doc.CreateElement("systemId");
                    var systemIdText = doc.CreateTextNode(_connector.SystemId);

                    systemId.AppendChild(systemIdText);
                    from.AppendChild(systemId);

                    var credential = doc.CreateElement("Credential");
                    var userName = doc.CreateElement("userName");
                    var password = doc.CreateElement("password");
                    var usernameText = doc.CreateTextNode(_connector.UserId);
                    var passwordText = doc.CreateTextNode(_connector.Password);
                    userName.AppendChild(usernameText);
                    password.AppendChild(passwordText);
                    credential.AppendChild(userName);
                    credential.AppendChild(password);
                    from.AppendChild(credential);

                    rootNode.AppendChild(from);

                    var to = doc.CreateElement("To");
                    var systemIdR = doc.CreateElement("systemId");
                    var systemIdRText = doc.CreateTextNode("REVINATE");
                    systemIdR.AppendChild(systemIdRText);
                    to.AppendChild(systemIdR);

                    var address = doc.CreateElement("address");
                    var addressText = doc.CreateTextNode(_connector.Url);
                    address.AppendChild(addressText);
                    to.AppendChild(address);

                    rootNode.AppendChild(to);

                    var timestamp = doc.CreateElement("timestamp");
                    var timestampText = doc.CreateTextNode("2015-09-09T12:00:00-07:00");
                    timestamp.AppendChild(timestampText);
                    rootNode.AppendChild(timestamp);

                    var token = doc.CreateElement("echoToken");
                    var tokenText = doc.CreateTextNode(new Guid().ToString());
                    token.AppendChild(tokenText);
                    rootNode.AppendChild(token);

                    var transactionId = doc.CreateElement("transactionId");
                    var transText = doc.CreateTextNode("123456");
                    transactionId.AppendChild(transText);
                    rootNode.AppendChild(transactionId);

                    var action = doc.CreateElement("action");
                    var actionText = doc.CreateTextNode("RESPONSE");
                    action.AppendChild(actionText);
                    rootNode.AppendChild(action);

                    var aMessageHeader = MessageHeader.CreateHeader("HTNGHeader", "http://htng.org/1.1/Header/", doc.InnerXml);
                    OperationContext.Current.OutgoingMessageHeaders.Add(aMessageHeader);

                }

Open in new window

The header should look like

<HTNGHeader xmlns="http://htng.org/1.1/Header/">
  <From>
    <systemId>systemId</systemId>
    <Credential>
      <userName>userName</userName>
      <password>password</password>
    </Credential>
  </From>
  <To>
    <systemId>RENIVATE</systemId>
    <address>https://mercer.revinate.com/interface/htng/ariandreservationpush</address>
  </To>
  <timestamp>2015-09-09T12:00:00-07:00</timestamp>
  <echoToken>123456789</echoToken>
  <transactionId>55678</transactionId>
  <action>RESPONSE</action>
</HTNGHeader>

But what I am actually getting is.

<HTNGHeader xmlns="http://htng.org/1.1/Header/">
<HTNGHeader>
  <From>
    <systemId>systemId</systemId>
    <Credential>
      <userName>userName</userName>
      <password>password</password>
    </Credential>
  </From>
  <To>
    <systemId>RENIVATE</systemId>
    <address>https://mercer.revinate.com/interface/htng/ariandreservationpush</address>
  </To>
  <timestamp>2015-09-09T12:00:00-07:00</timestamp>
  <echoToken>123456789</echoToken>
  <transactionId>55678</transactionId>
  <action>RESPONSE</action>
</HTNGHeader>
</HTNGHeader>

As you can see there is the extra layer of the root element.

Try this:

using (new OperationContextScope(_svc.InnerChannel))
{
    var doc = new XmlDocument();

    var rootNode = doc.CreateElement("HTNGHeader", "http://htng.org/1.1/Header/");

    doc.AppendChild(rootNode);

    var from = doc.CreateElement("From");

    var systemId = doc.CreateElement("systemId");
    var systemIdText = doc.CreateTextNode(_connector.SystemId);

    systemId.AppendChild(systemIdText);
    from.AppendChild(systemId);

    var credential = doc.CreateElement("Credential");
    var userName = doc.CreateElement("userName");
    var password = doc.CreateElement("password");
    var usernameText = doc.CreateTextNode(_connector.UserId);
    var passwordText = doc.CreateTextNode(_connector.Password);
    userName.AppendChild(usernameText);
    password.AppendChild(passwordText);
    credential.AppendChild(userName);
    credential.AppendChild(password);
    from.AppendChild(credential);

    rootNode.AppendChild(from);

    var to = doc.CreateElement("To");
    var systemIdR = doc.CreateElement("systemId");
    var systemIdRText = doc.CreateTextNode("REVINATE");
    systemIdR.AppendChild(systemIdRText);
    to.AppendChild(systemIdR);

    var address = doc.CreateElement("address");
    var addressText = doc.CreateTextNode(_connector.Url);
    address.AppendChild(addressText);
    to.AppendChild(address);

    rootNode.AppendChild(to);

    var timestamp = doc.CreateElement("timestamp");
    var timestampText = doc.CreateTextNode("2015-09-09T12:00:00-07:00");
    timestamp.AppendChild(timestampText);
    rootNode.AppendChild(timestamp);

    var token = doc.CreateElement("echoToken");
    var tokenText = doc.CreateTextNode(new Guid().ToString());
    token.AppendChild(tokenText);
    rootNode.AppendChild(token);

    var transactionId = doc.CreateElement("transactionId");
    var transText = doc.CreateTextNode("123456");
    transactionId.AppendChild(transText);
    rootNode.AppendChild(transactionId);

    var action = doc.CreateElement("action");
    var actionText = doc.CreateTextNode("RESPONSE");
    action.AppendChild(actionText);
    rootNode.AppendChild(action);

	//var aMessageHeader = MessageHeader.CreateHeader("HTNGHeader", "http://htng.org/1.1/Header/", doc.InnerXml);
	//OperationContext.Current.OutgoingMessageHeaders.Add(aMessageHeader);

Or using built-in serialization:

namespace ConsoleCS
{
    using System;
    using System.Xml.Serialization;

    public enum Action { RESPONSE, REQUEST }

    public class Credential
    {
        public string UserName { get; set; }
        public string Password { get; set; }
    }

    public class From
    {
        public string SystemID { get; set; }
        public Credential Credential { get; set; }
    }

    public class To
    {
        public string SystemID { get; set; }
        public string Address { get; set; }
    }

    public class HTNGHeader
    {
        public From From { get; set; }
        public To To { get; set; }
        public DateTime TimeStamp { get; set; }
        public string EchoToken { get; set; }
        public int TransactionID { get; set; }
        public Action Action { get; set; }
    }

    class Program
    {

        static void Main(string[] args)
        {
            XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
            namespaces.Add("ns", "http://contoso.com");
            XmlSerializer xser = new XmlSerializer(typeof(HTNGHeader));
            HTNGHeader obj = new HTNGHeader();
            obj.Action = Action.RESPONSE;
            obj.EchoToken = "EchoToken";
            obj.TimeStamp = DateTime.Now;
            obj.TransactionID = 123456789;
            obj.From = new From() { SystemID = "SystemID", Credential = new Credential() { UserName = "UserName", Password = "Password" } };
            obj.To = new To() { SystemID = "SystemID", Address = "http://contoso.com" };
            xser.Serialize(Console.Out, obj, namespaces);

            Console.WriteLine("Done.");
            Console.ReadLine();
        }
