Comentarios

Use esta sobrecarga si desea obtener una lista completa de todas las colas públicas de la red. Si desea restringir la lista por determinados criterios, como MachineName, Categoryo la hora de la última modificación, use otra sobrecarga de este método. (Como alternativa, puede usar GetPublicQueuesByMachine(String), GetPublicQueuesByCategory(Guid)o GetPublicQueuesByLabel(String)).

GetPublicQueues recupera una instantánea estática de las colas. Para interactuar con una lista dinámica de las colas, use GetMessageQueueEnumerator.

En la tabla siguiente se muestra si este método está disponible en varios modos de grupo de trabajo.

Comentarios

Si desea filtrar todas las colas públicas de la red por etiqueta, categoría o nombre de equipo, la MessageQueue clase contiene métodos específicos que proporcionan esa funcionalidad (GetPublicQueuesByLabel(String), GetPublicQueuesByCategory(Guid)y GetPublicQueuesByMachine(String), respectivamente). Use esta sobrecarga para obtener una lista de todas las colas públicas de la red que cumplan más de uno de estos criterios (por ejemplo, si desea especificar una etiqueta y una categoría). También puede filtrar por criterios de mensaje distintos de Label, Categoryy MachineName. Por ejemplo, esta sobrecarga se usa para filtrar por la hora de última modificación de una cola. Simplemente cree una nueva instancia de la MessageQueueCriteria clase , establezca las propiedades adecuadas en la instancia y pase la instancia como el criteria parámetro .

GetPublicQueues recupera una instantánea estática de las colas. Para interactuar con una lista dinámica de las colas, use GetMessageQueueEnumerator.

En la tabla siguiente se muestra si este método está disponible en varios modos de grupo de trabajo.

Modo de grupo de trabajo	Disponible
Equipo local	No
Equipo local y nombre de formato directo	No
Equipo remoto	No
Equipo remoto y nombre de formato directo	No
