Canceled 2

La registrazione corrente è stata annullata dall'utente.The current registration was canceled by the user.

Failed 1

La notifica non è riuscita per un motivo qualsiasi.The notification failed for any reason.

NotApplicable 4

Questo risultato può essere causato dalle condizioni seguenti: non esistono registrazioni correnti per una notifica di Garbage Collection, la Garbage Collection simultanea è abilitata o il tempo specificato per il parametro millisecondsTimeout è scaduto e non sono state ottenute notifiche di Garbage Collection.This result can be caused by the following: there is no current registration for a garbage collection notification, concurrent garbage collection is enabled, or the time specified for the millisecondsTimeout parameter has expired and no garbage collection notification was obtained. Vedere l'impostazione di runtime <gcConcurrent> per informazioni su come disabilitare la Garbage Collection simultanea.(See the <gcConcurrent> runtime setting for information about how to disable concurrent garbage collection.)

Succeeded 0

La notifica è riuscita e la registrazione non è stata annullata.The notification was successful and the registration was not canceled.

Timeout 3

Il tempo specificato dal parametro millisecondsTimeout per WaitForFullGCApproach(Int32) o WaitForFullGCComplete(Int32) è trascorso.The time specified by the millisecondsTimeout parameter for either WaitForFullGCApproach(Int32) or WaitForFullGCComplete(Int32) has elapsed.

Esempio

Nell'esempio seguente viene ottenuta un' GCNotificationStatus enumerazione dal WaitForFullGCApproach metodo.The following example obtains a GCNotificationStatus enumeration from the WaitForFullGCApproach method. Se l'enumerazione restituisce Succeeded, chiama il metodo personalizzato OnFullGCApproachNotify per eseguire azioni in risposta alla Garbage Collection completa vicina.If the enumeration returns Succeeded, it calls the custom method OnFullGCApproachNotify to perform actions in response to the approaching full garbage collection. Questo esempio di codice fa parte di un esempio più ampio fornito per le notifiche di Garbage Collection .This code example is part of a larger example provided for Garbage Collection Notifications topic.

Commenti

Usare il RegisterForFullGCNotification metodo per eseguire la registrazione per una notifica di Garbage Collection completa.Use the RegisterForFullGCNotification method to register for a full garbage collection notification. Usare quindi il WaitForFullGCApproach metodo o il WaitForFullGCComplete metodo per restituire un' GCNotificationStatus enumerazione che contiene lo stato della notifica.Then use the WaitForFullGCApproach method or the WaitForFullGCComplete method to return a GCNotificationStatus enumeration that contains the status of the notification.
