Consume Web Service with soap:mustUnderstand attribute

This is my sample Code for Web service. I'm new to SOAP application if someone can spot any problem here it's much appreciated. This error only happened if mustUnderstand attribute ="1" 

  [WebService(Namespace = "http://www.xxxx.co.uk/Integration/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    public class ADNHeaderContact : System.Web.Services.WebService
    {

        public MyHeader myHeader;


        [WebMethod]
        [SoapHeader("myHeader")]

        public string HelloWorld()
        {

            XmlDocument xmlSoapRequest = new XmlDocument();
            using (Stream receiveStream = HttpContext.Current.Request.InputStream)
            {
                receiveStream.Position = 0;
                using (StreamReader readStream =
                                       new StreamReader(receiveStream, Encoding.UTF8))
                {
                    xmlSoapRequest.Load(readStream);
                }
            }


            using (XmlBreaker readxml = new XmlBreaker())
            {
                using (ReponseSaveApplications respose = new ReponseSaveApplications())
                {

                    return ("Hello");


                }

            };
        }

    }

SoapHeader.MustUnderstand Property

When an XML Web service client adds a SOAP header to an XML Web service method call with the MustUnderstand property set to true, the XML Web service method must set the DidUnderstand property to true; otherwise, a SoapHeaderException is thrown back to the XML Web service client by ASP.NET.
