WS-Addressing endpoint Specification

WS-Addressing endpoint specification WS-Addressing provides a unified and standardized Addressing mode for SOAP messages. One of the core of this standard is the endpoint specification. The MessageHeader type is the CLR abstraction of the SOAP message header block. It can be assumed that the MessageHeader object is the CLR abstraction of the Endpoint reference specification. The IsReferenceParameter read-only attribute indicates whether the MessageHeader object is a WS-Addressing reference parameter or reference attribute. MessageHeaders-type SOAP messages may contain many header blocks, which indicate methods for a group of header block objects. MessageHeaders is used for this purpose. The read-only attribute Headers of the MessageHeaders type is mainly used to add, modify, query, and remove MessageHeader in Message. MessageHeaders is a specific class, not an abstract class. It does not contain factory methods. Add MessageHeader: [csharp] MessageHeaders headers = new MessageHeaders (MessageVersion. soap12WSAddressingAugust2004); headers. add (messageHeader); headers. insert (0, messageHeader); MessageHeaders headers = new MessageHeaders (MessageVersion. soap12WSAddressingAugust2004); headers. add (messageHeader); headers. insert (0, messageHeader); get the value of MessageHeader: [csharp] urchaseOrderInfo purchaseOrderInfo = new Pu RchaseOrderInfo (1000, DateTime. utcNow, 10.92d); string WSAddNS = "http://www.andersoft.com/messageheader"; MessageHeader messageHeader = MessageHeader. createHeader ("MessageID", WSAddNS, purchaseOrderInfo); Stream stream = new MemoryStream (); XmlDictionaryWriter writer = XmlDictionaryWriter. createTextWriter (stream, Encoding.
