OperationFlow-Enumeration

  • Artikel

Gibt den Übertragungstyp an, den ein Endpunkt des xml-Webdiensts unterstützen kann.

Namespace: System.Web.Services.Description
Assembly: System.Web.Services (in system.web.services.dll)

Syntax

'Declaration
Public Enumeration OperationFlow
'Usage
Dim instance As OperationFlow

public enum OperationFlow

public enum class OperationFlow

public enum OperationFlow

public enum OperationFlow

Member

  Membername Beschreibung
None Gibt an, dass der Endpunkt des XML-Webdiensts keine Übertragungen empfängt. 
Notification Gibt an, dass der Endpunkt des XML-Webdiensts eine Meldung sendet. 
OneWay Gibt an, dass der Endpunkt des XML-Webdiensts eine Meldung empfängt. 
RequestResponse Gibt an, dass der Endpunkt des XML-Webdiensts eine Meldung empfängt und anschließend eine korrelierte Meldung sendet. 
SolicitResponse Gibt an, dass der Endpunkt des XML-Webdiensts eine Meldung sendet und anschließend eine korrelierte Meldung empfängt. 

Hinweise

Obwohl RequestResponse-Operationen bzw. SolicitResponse-Operationen im WSDL-Dokument (Web Services Description Language-Dokument) eine logische Korrelation zueinander aufweisen, werden die konkreten Korrelationsinformationen durch eine Bindung angegeben. Die Anforderungs- und Antwortmeldungen können z. B. als Teil von ein oder zwei tatsächlichen HTTP-Übertragungen ausgetauscht werden.

Beispiel

Das folgende Beispiel veranschaulicht die Verwendung der OperationFlow-Enumeration.
