Canceled Canceled Canceled Canceled 2

Текущая регистрация отменена пользователем.The current registration was canceled by the user.

Failed Failed Failed Failed 1

Не удалось отправить уведомление по любой причине.The notification failed for any reason.

NotApplicable NotApplicable NotApplicable NotApplicable 4

Данный результат может быть вызван следующим: нет текущей регистрации для уведомления о сборке мусора, разрешена параллельная сборка мусора или время, указанное для параметра millisecondsTimeout, истекло, поэтому уведомление о сборке мусора не было получено.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. (Сведения об отключении параллельной сборки мусора см. в статье, посвященной параметру среды выполнения <gcConcurrent>.)(See the <gcConcurrent> runtime setting for information about how to disable concurrent garbage collection.)

Succeeded Succeeded Succeeded Succeeded 0

Уведомление успешно отправлено, и регистрация не отменена.The notification was successful and the registration was not canceled.

Timeout Timeout Timeout Timeout 3

Время, указанное в параметре millisecondsTimeout для метода WaitForFullGCApproach(Int32) или WaitForFullGCComplete(Int32), истекло.The time specified by the millisecondsTimeout parameter for either WaitForFullGCApproach(Int32) or WaitForFullGCComplete(Int32) has elapsed.

Примеры

Следующий пример получает GCNotificationStatus перечисления из WaitForFullGCApproach метод.The following example obtains a GCNotificationStatus enumeration from the WaitForFullGCApproach method. Если перечисление возвращает успешно, он вызывает пользовательский метод OnFullGCApproachNotify для выполнения действий в ответ на approaching полной сборки мусора.If the enumeration returns Succeeded, it calls the custom method OnFullGCApproachNotify to perform actions in response to the approaching full garbage collection. Данный пример кода является частью большего примера для уведомлений сборки мусора раздела.This code example is part of a larger example provided for Garbage Collection Notifications topic.

Комментарии

Используйте RegisterForFullGCNotification метод регистрации уведомление о полной сборке мусора.Use the RegisterForFullGCNotification method to register for a full garbage collection notification. Затем с помощью WaitForFullGCApproach метод или WaitForFullGCComplete метод для возврата GCNotificationStatus перечисление, содержащее состояние уведомления.Then use the WaitForFullGCApproach method or the WaitForFullGCComplete method to return a GCNotificationStatus enumeration that contains the status of the notification.
