備註

如果您想要依標籤、類別或計算機名稱篩選網路上的所有公用佇列，類別 MessageQueue 會包含特定方法， GetPublicQueuesByLabel(String)分別提供 (、 GetPublicQueuesByCategory(Guid)和 GetPublicQueuesByMachine(String)的功能) 。 使用此多載來取得網路上符合多個 (準則的所有公用佇列清單，例如，如果您想要同時指定標籤和類別) ， 您也可以依、 Category和 MachineName以外的Label訊息準則進行篩選。 例如，您可以使用這個多載，依佇列的上次修改時間進行篩選。 只要建立 類別的新實例 MessageQueueCriteria ，在 實例中設定適當的屬性，然後將 實例當做 criteria 參數傳遞。

GetPublicQueues 擷取佇列的靜態快照集。 若要與佇列的動態清單互動，請使用 GetMessageQueueEnumerator。

下表顯示這個方法是否可在各種工作組模式中使用。
