Question

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，对此深表感谢。仅当mustUnderstand属性=“ 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");


                }

            };
        }

    }

Answer 1

SoapHeader.MustUnderstand Property

当XML Web服务客户端将SOAP标头添加到XML Web时   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抛出回到XML Web服务   客户端通过ASP.NET。

使用soap：mustUnderstand属性消费Web服务
