c# - Clueless about how to create SOAP <wsse:Security> header

Question

I'm have near to none experience with SOAP protocol. The service I need to connect to required header. I think this is somewhat standard in Java but in C# one must create this header by hand.

Does anyone here been able to connect to similar service: have created the header or maybe even know about some standard library which would simplify creation of header? Can you share some code or references?

I also found a clue that maybe header will be generated if using WS2005, because there is WS3 addin for it. Can anybody comment this? After quick look at this addin I found simmilar fields as in Security header, but still wasn't able to create the header.

We were able to solve it with the following code:

public class SecurityHeader : System.ServiceModel.Channels.MessageHeader {
    public string userName;
    public string password;

    protected override void OnWriteStartHeader (System.Xml.XmlDictionaryWriter writer, System.ServiceModel.Channels.MessageVersion messageVersion)
    {
        writer.WriteStartElement("wsse", Name, Namespace);
        writer.WriteXmlnsAttribute("wsse", Namespace);
    }

    protected override void OnWriteHeaderContents (System.Xml.XmlDictionaryWriter writer, System.ServiceModel.Channels.MessageVersion messageVersion)
    {
        writer.WriteStartElement("wsse", "UsernameToken", Namespace);

        writer.WriteStartElement("wsse", "Username", Namespace);
        writer.WriteValue(userName);
        writer.WriteEndElement();

        writer.WriteStartElement("wsse", "Password", Namespace);
        writer.WriteValue(password);
        writer.WriteEndElement();

        writer.WriteEndElement();

    }

    public override string Name
    {
        get { return "Security"; }
    }

    public override string Namespace
    {
        get { return "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"; }
    }
}

This wrote the header that was required by the DataPower box.

How to use the class SecurityHeader

    public static void Main(string[] args)
    {

        var webService = new ServiceReference1.MyWebService();
        ....
       webService.Open();


        using (OperationContextScope scope = new OperationContextScope((IContextChannel)webService.InnerChannel))
        {

            var myObjRequest = GetMyObjRequest();

            MessageHeaders messageHeadersElement = OperationContext.Current.OutgoingMessageHeaders;
            messageHeadersElement.Add(SecurityHeader("UserName", "Password"))


             var res = webService.MyServe(myObjRequest);
            Console.WriteLine(res.ToString());
        }
    }
