public:
 property long PeakPagedMemorySize64 { long get(); };

public long PeakPagedMemorySize64 { get; }

member this.PeakPagedMemorySize64 : int64

Public ReadOnly Property PeakPagedMemorySize64 As Long

Wartość właściwości

Int64

Maksymalna ilość pamięci w bajtach przydzielona w pliku stronicowania pamięci wirtualnej dla skojarzonego procesu, ponieważ została uruchomiona.

Przykłady

Poniższy przykład kodu uruchamia wystąpienie aplikacji Notatnik. Następnie przykład pobiera i wyświetla różne właściwości skojarzonego procesu. Przykład wykrywa, kiedy proces kończy się, i wyświetla kod zakończenia i statystyki szczytowej pamięci.

Uwagi

Wartość zwrócona przez tę wartość właściwości reprezentuje maksymalny rozmiar pamięci w pliku stronicowania pamięci wirtualnej używanym przez proces od momentu uruchomienia w bajtach. System operacyjny używa pliku stronicowania pamięci wirtualnej w połączeniu z pamięcią fizyczną do zarządzania wirtualną przestrzenią adresową dla każdego procesu. Gdy pamięć stronicowana nie jest używana, można ją przenieść do pliku stronicowania pamięci wirtualnej na dysku.

Ta właściwość może służyć do monitorowania użycia pamięci na komputerach z procesorami 32-bitowymi lub procesorami 64-bitowymi. Wartość właściwości jest równoważna licznikowi wydajności Szczytowe bajty pliku strony dla tego procesu.
