Message.AcknowledgeType 속성

정의

보내는 애플리케이션으로 반환되는 승인 메시지의 형식을 가져오거나 설정합니다.

public:
 property System::Messaging::AcknowledgeTypes AcknowledgeType { System::Messaging::AcknowledgeTypes get(); void set(System::Messaging::AcknowledgeTypes value); };
[System.Messaging.MessagingDescription("MsgAcknowledgeType")]
public System.Messaging.AcknowledgeTypes AcknowledgeType { get; set; }
[<System.Messaging.MessagingDescription("MsgAcknowledgeType")>]
member this.AcknowledgeType : System.Messaging.AcknowledgeTypes with get, set
Public Property AcknowledgeType As AcknowledgeTypes

속성 값

시스템이 관리 큐에 게시하는 승인 메시지의 형식과 보내는 애플리케이션으로 승인이 반환되는 조건을 나타내는 AcknowledgeTypes 값 중 하나입니다. 기본값은 None입니다.

특성

예외

메시지가 AcknowledgeType 속성을 무시하도록 필터링됩니다.

예제

다음 코드 예제에서는 큐에서 주문을 포함 하는 메시지를 송수신 설정 합니다. 원본 메시지가 도달 하거나이 특히 긍정 승인을 요청 큐에서 검색 합니다.

설명

AcknowledgeType 속성 보내는 애플리케이션에 필요한 승인 메시지의 형식을 지정 합니다. AcknowledgeType 메시지를 보내기 전에 속성을 설정하여 특정 항목에 대한 알림을 요청합니다(예: 대상 큐에 도달하는 메시지, 검색되는 메시지 또는 대상 큐에서 메시지가 도달하거나 검색되지 않도록 하는 시간 제한).

메시지 큐에서 승인 메시지를 보내 알림 반환 된 AdministrationQueue 원본 메시지에서 지정 된 속성입니다. 승인 메시지의 Acknowledgment 속성 나타내는 승인의 유형을 나타냅니다. 예를 들어 메시지 하기 전에 대상에 도달 하지 않았습니다 않으므로 승인 메시지를 보낼 수는 TimeToReachQueue 간격이 만료 합니다 Acknowledgment 승인 메시지의 속성 값이 포함 됩니다 ReachQueueTimeout합니다.
