システムによって生成される受信確認メッセージ用の管理キューを指定する MessageQueue。既定値は null 参照 (Visual Basic では Nothing) です。


AdministrationQueue プロパティに指定できるキューは、任意の非トランザクション キューです。管理キューに送信される受信確認メッセージは、元のメッセージが送信先キューに到達したかどうか、メッセージがキューから削除されたかどうかを示すことができます。
AcknowledgeType プロパティの値が None 以外のときには、送信元アプリケーションは管理キューとして使うキューを指定する必要があります。

オーダーを含んでいるメッセージをキューに送信し、またオーダーを含んでいるメッセージをキューから受信するコード例を次に示します。これは特に、元のメッセージがキューに到着するか、元のメッセージがキューから取得されたときに、肯定受信確認を要求します。
