Ejemplos

En el ejemplo siguiente se muestra cómo usar esta propiedad al diagnosticar un problema con un trabajo de impresión.

Comentarios

Puede parecer paradójico al principio que un objeto puede notificar su propio estado como eliminado, pero tenga en cuenta que el PrintSystemJobInfo objeto solo representa un trabajo de impresión real. La eliminación de esta última de su cola de impresión no elimina automáticamente el objeto de la PrintSystemJobInfo aplicación. Del mismo modo, el objeto no se quita de ninguno PrintJobInfoCollection que se creó antes de que se eliminara el trabajo de impresión que representa. Por ejemplo, si el GetPrintJobInfoCollection método se ejecuta antes de eliminar el trabajo de impresión, la colección devuelta incluirá un PrintSystemJobInfo objeto que representa el trabajo de impresión. Este objeto no se quita de la colección cuando se elimina el trabajo de impresión. Pero si GetPrintJobInfoCollection se vuelve a ejecutar, la colección devuelta no tendrá miembros que representen los trabajos de impresión eliminados.
