【问题描述】：

这是我的 Web 服务示例代码。如果有人可以在这里发现任何问题，我是 SOAP 应用程序的新手，非常感谢。仅当 mustUnderstand attribute ="1" 时才会发生此错误

  [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");


                }

            };
        }

    }

【解决方案1】：

SoapHeader.MustUnderstand Property

当 XML Web 服务客户端将 SOAP 标头添加到 XML Web 将 MustUnderstand 属性设置为 true 的服务方法调用， XML Web 服务方法必须将 DidUnderstand 属性设置为 true；否则，将 SoapHeaderException 抛出回 XML Web 服务 ASP.NET 客户端。
