Ruft alle öffentlichen Warteschlangen auf dem angegebenen Computer ab.
Namespace: System.Messaging
Assembly: System.Messaging (in system.messaging.dll)
Syntax
'Declaration
Public Shared Function GetPublicQueuesByMachine ( _
machineName As String _
) As MessageQueue()
'Usage
Dim machineName As String
Dim returnValue As MessageQueue()
returnValue = MessageQueue.GetPublicQueuesByMachine(machineName)
public static MessageQueue[] GetPublicQueuesByMachine (
string machineName
)
public:
static array<MessageQueue^>^ GetPublicQueuesByMachine (
String^ machineName
)
public static MessageQueue[] GetPublicQueuesByMachine (
String machineName
)
public static function GetPublicQueuesByMachine (
machineName : String
) : MessageQueue[]
Parameter
- machineName
Der Name des Computers mit der Gruppe der abzurufenden öffentlichen Warteschlangen.
Rückgabewert
Ein Array von MessageQueue-Objekten, die auf die öffentlichen Warteschlangen auf dem Computer verweisen.
Ausnahmen
| Ausnahmetyp | Bedingung |
|---|---|
Die Syntax des machineName-Parameters ist falsch. |
|
Fehler beim Zugriff auf eine Message Queuing-Methode. |
Hinweise
Verwenden Sie diese Methode zum Filtern der öffentlichen Warteschlangen nach Computer.
GetPublicQueuesByMachine ruft einen statischen Snapshot der Warteschlangen ab. Verwenden Sie GetMessageQueueEnumerator zur Interaktion mit einer dynamischen Liste der Warteschlangen. Sie können den Computernamen als Teil der MessageQueueCriteria angeben, die Sie an die Methode übergeben.
Der folgenden Tabelle können Sie entnehmen, ob diese Methode in verschiedenen Arbeitsgruppenmodi verfügbar ist.
