如何在WebService中读取BeforeDeserialize中的SoapHeader

Question

我如何在BeforeDeserialize中读取SoapHeader，我尝试了一下，但它不起作用。任何解决方案或简单的示例。谢谢。

    public class TicketIdentity
    {
        private string ticket;

        public string Ticket
        {
            get { return ticket; }
        }

        public TicketIdentity(string _ticket)
        {
            this.ticket = _ticket;
        }
    }

    public class TicketHeader : SoapHeader
    {
        public string Ticket;
        public TicketHeader(string ticket)
        {
            Ticket = ticket;
        }
        public TicketHeader()
        { }
    }

...

   string Key;

        public override void ProcessMessage(SoapMessage message)
        {
            switch (message.Stage)
            {
                case SoapMessageStage.BeforeSerialize:
                    break;
                case SoapMessageStage.AfterSerialize:
                    break;
                case SoapMessageStage.BeforeDeserialize:
                    {
                     foreach (SoapHeader header in message.Headers)
                         {
                         if (header is TicketHeader)
                            {
                            TicketHeader tempHeader = (TicketHeader)header;
                            Key = tempHeader.Ticket;
                            }
                         }
                    }
                    break;
                case SoapMessageStage.AfterDeserialize:
                    break;
                default:
                    throw new ArgumentException("Chyba pri serializacii SOAP msg.");
            }
        }

在反序列化之前，标头也是序列化的，因为它们的形式是。因此，您不能将消息头与业务对象进行比较，因为需要对消息进行反序列化。
