MessageQueue.GetPrivateQueuesByMachine(String) MessageQueue.GetPrivateQueuesByMachine(String) MessageQueue.GetPrivateQueuesByMachine(String) MessageQueue.GetPrivateQueuesByMachine(String) Method

定義

擷取所指定電腦上的所有私用佇列。Retrieves all the private queues on the specified computer.

public:
 static cli::array <System::Messaging::MessageQueue ^> ^ GetPrivateQueuesByMachine(System::String ^ machineName);
public static System.Messaging.MessageQueue[] GetPrivateQueuesByMachine (string machineName);
static member GetPrivateQueuesByMachine : string -> System.Messaging.MessageQueue[]
Public Shared Function GetPrivateQueuesByMachine (machineName As String) As MessageQueue()

參數

machineName
String String String String

要從其中擷取私用佇列的電腦。The computer from which to retrieve the private queues.

傳回

MessageQueue 物件的陣列,會參考擷取的私用佇列。An array of MessageQueue objects that reference the retrieved private queues.

例外狀況

machineName 參數為 null 或空字串 ("")。The machineName parameter is null or an empty string ("").

存取訊息佇列方法時發生錯誤。An error occurred when accessing a Message Queuing method.

範例

下列程式碼範例會抓取佇列的清單。The following code example retrieves lists of queues.
