Canceled 2

O registro atual foi cancelado pelo usuário.The current registration was canceled by the user.

Failed 1

A notificação falhou por algum motivo.The notification failed for any reason.

NotApplicable 4

Esse resultado pode ser causado pelos seguintes: não há nenhum registro atual para uma notificação de coleta de lixo, a coleta de lixo simultânea está habilitada ou o tempo especificado para o parâmetro millisecondsTimeout expirou e nenhuma notificação de coleta de lixo foi obtida.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. (Consulte a configuração de runtime <gcConcurrent> para obter informações sobre como desabilitar a coleta de lixo simultânea).(See the <gcConcurrent> runtime setting for information about how to disable concurrent garbage collection.)

Succeeded 0

A notificação foi bem-sucedida e o registro não foi cancelado.The notification was successful and the registration was not canceled.

Timeout 3

A hora especificada pelo parâmetro millisecondsTimeout para WaitForFullGCApproach(Int32) ou WaitForFullGCComplete(Int32) foi decorrida.The time specified by the millisecondsTimeout parameter for either WaitForFullGCApproach(Int32) or WaitForFullGCComplete(Int32) has elapsed.

Exemplos

O exemplo a seguir obtém uma GCNotificationStatus enumeração do WaitForFullGCApproach método.The following example obtains a GCNotificationStatus enumeration from the WaitForFullGCApproach method. Se a enumeração retornar com êxito, ela chamará o método personalizado OnFullGCApproachNotify para executar ações em resposta à abordagem de coleta de lixo completa.If the enumeration returns Succeeded, it calls the custom method OnFullGCApproachNotify to perform actions in response to the approaching full garbage collection. Este exemplo de código é parte de um exemplo maior fornecido para o tópico notificações de coleta de lixo .This code example is part of a larger example provided for Garbage Collection Notifications topic.

Comentários

Use o RegisterForFullGCNotification método para se registrar para uma notificação de coleta de lixo completa.Use the RegisterForFullGCNotification method to register for a full garbage collection notification. Em seguida, use o WaitForFullGCApproach método ou o WaitForFullGCComplete método para retornar uma GCNotificationStatus enumeração que contém o status da notificação.Then use the WaitForFullGCApproach method or the WaitForFullGCComplete method to return a GCNotificationStatus enumeration that contains the status of the notification.
