Beispiele

Im folgenden Codebeispiel wird eine Nachricht gesendet und empfangen, die eine Bestellung zu und aus einer Warteschlange enthält.The following code example sends and receives a message containing an order to and from a queue. Insbesondere wird eine positive Bestätigung angefordert, wenn die ursprüngliche Nachricht erreicht oder aus der Warteschlange abgerufen wird.It specifically requests a positive acknowledgment when the original message reaches or is retrieved from the queue.

Hinweise

Die Acknowledgment -Klasse definiert die Typen von Bestätigungsnachrichten, die Beiträge in der Verwaltungs Warteschlange Message Queuing, sowie die Bedingungen, die bewirken, dass eine Bestätigungsnachricht gesendet wird.The Acknowledgment class defines the types of acknowledgment messages that Message Queuing posts in the administration queue and the conditions that cause an acknowledgment message to be sent. Bestätigungs Typen können in vier Gruppen unterteilt werden: positive Eingangsbestätigungen, positive Lese Bestätigungen, negative Eingangsbestätigungen und negative Lese Bestätigungen.Acknowledgment types can be divided broadly into four groups: positive arrival acknowledgments, positive read acknowledgments, negative arrival acknowledgments, and negative read acknowledgments.

Die der Nachricht zugeordnete Verwaltungs Warteschlange wird Message.AdministrationQueue in der-Eigenschaft angegeben.The administration queue associated with message is specified in the Message.AdministrationQueue property.

Message Queuing legt die Message.Acknowledgment -Eigenschaft auf einen Acknowledgment der-Enumerationswerte fest, wenn eine Bestätigungsnachricht erstellt wird.Message Queuing sets the Message.Acknowledgment property to one of the Acknowledgment enumeration values when it creates an acknowledgment message. Der Message.Acknowledgment Eigenschafts Wert ist in der Regel nur dann sinnvoll, wenn sich die Instanz auf eine vom System gesendete Bestätigungsnachricht bezieht.The Message.Acknowledgment property value is typically meaningful only when the instance refers to a system-sent acknowledgment message. Wenn die Message.Acknowledgment Eigenschaft für eine andere Nachricht als eine Bestätigungsnachricht gelesen wird, wird eine Ausnahme ausgelöst.Reading the Message.Acknowledgment property for a message other than an acknowledgment message throws an exception.

Message Queuing sendet keine Bestätigungsnachricht, wenn dies von der sendenden Anwendung angefordert wird.Message Queuing does not send an acknowledgment message unless the sending application requests that it do so. Die Anwendung führt diese Anforderung aus, indem Sie den entsprechenden Wert Message.AcknowledgeType für die Eigenschaft festlegt.Your application makes this request by setting the appropriate value for the Message.AcknowledgeType property. Message Queuing sendet alle Bestätigungsnachrichten an die Verwaltungs Warteschlange, die AdministrationQueue in der-Eigenschaft Messagedes Originals angegeben ist.Message Queuing sends all acknowledgment messages to the administration queue specified in the AdministrationQueue property of the original Message.
