Canceled Canceled Canceled Canceled 2

El usuario canceló el registro actual.The current registration was canceled by the user.

Failed Failed Failed Failed 1

Error en la notificación por algún motivo.The notification failed for any reason.

NotApplicable NotApplicable NotApplicable NotApplicable 4

Este resultado puede deberse a lo siguiente: no hay ningún registro actual para una notificación de recolección de elementos no utilizados, la recolección de elementos no utilizados simultánea está habilitada o el tiempo especificado para el parámetro millisecondsTimeout ha expirado y se ha obtenido ninguna notificación de recolección de elementos no utilizados.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. (Vea la configuración en tiempo de ejecución <gcConcurrent> para obtener información sobre cómo deshabilitar la recolección de elementos no utilizados simultánea).(See the <gcConcurrent> runtime setting for information about how to disable concurrent garbage collection.)

Succeeded Succeeded Succeeded Succeeded 0

La notificación se realizó correctamente y no se canceló el registro.The notification was successful and the registration was not canceled.

Timeout Timeout Timeout Timeout 3

La hora especificada por el parámetro millisecondsTimeout para WaitForFullGCApproach(Int32) o WaitForFullGCComplete(Int32) ha transcurrido.The time specified by the millisecondsTimeout parameter for either WaitForFullGCApproach(Int32) or WaitForFullGCComplete(Int32) has elapsed.

Ejemplos

En el ejemplo siguiente se obtiene GCNotificationStatus una enumeración del método.WaitForFullGCApproachThe following example obtains a GCNotificationStatus enumeration from the WaitForFullGCApproach method. Si la enumeración devuelve Succeeded, llama al método OnFullGCApproachNotify personalizado para realizar acciones en respuesta a la recolección de elementos no utilizados completa.If the enumeration returns Succeeded, it calls the custom method OnFullGCApproachNotify to perform actions in response to the approaching full garbage collection. Este ejemplo de código forma parte de un ejemplo más grande proporcionado para el tema notificaciones de recolección de elementos no utilizados .This code example is part of a larger example provided for Garbage Collection Notifications topic.

Comentarios

Use el RegisterForFullGCNotification método para registrar una notificación de recolección de elementos no utilizados completa.Use the RegisterForFullGCNotification method to register for a full garbage collection notification. A continuación, WaitForFullGCApproach use el método WaitForFullGCComplete o el método para GCNotificationStatus devolver una enumeración que contiene el estado de la notificación.Then use the WaitForFullGCApproach method or the WaitForFullGCComplete method to return a GCNotificationStatus enumeration that contains the status of the notification.
