Niektóre informacje odnoszą się do produktu w wersji wstępnej, który może zostać znacząco zmodyfikowany przed wydaniem. Firma Microsoft nie udziela żadnych gwarancji, jawnych lub domniemanych, w odniesieniu do informacji podanych w tym miejscu.

Pobiera liczbę profilów w źródle danych, w którym miała miejsce ostatnia data działania lub przed określonym userInactiveSinceDate.

public:
 override int GetNumberOfInactiveProfiles(System::Web::Profile::ProfileAuthenticationOption authenticationOption, DateTime userInactiveSinceDate);

public override int GetNumberOfInactiveProfiles (System.Web.Profile.ProfileAuthenticationOption authenticationOption, DateTime userInactiveSinceDate);

override this.GetNumberOfInactiveProfiles : System.Web.Profile.ProfileAuthenticationOption * DateTime -> int

Public Overrides Function GetNumberOfInactiveProfiles (authenticationOption As ProfileAuthenticationOption, userInactiveSinceDate As DateTime) As Integer

Parametry

authenticationOption: ProfileAuthenticationOption

ProfileAuthenticationOption Jedna z wartości, określająca, czy są zwracane anonimowe, uwierzytelnione, czy oba typy profilów.

userInactiveSinceDate: DateTime

Element DateTime określający, które profile użytkowników są uznawane za nieaktywne. LastActivityDate Jeśli profil użytkownika występuje w dniu lub przed tą datą i godziną, profil jest uznawany za nieaktywny.

Zwraca

Int32

Liczba profilów w źródle danych, dla których miała miejsce ostatnia data działania przed określoną datą i godziną.

Przykłady

Poniższy przykład kodu umożliwia użytkownikowi wyświetlanie i usuwanie aktywnych i nieaktywnych informacji profilów na podstawie kryteriów wyszukiwania. Liczba nieaktywnych profilów jest wyświetlana przy użyciu wyników GetNumberOfInactiveProfiles metody .

Uwagi

Metoda GetNumberOfInactiveProfiles służy do pobierania liczby wszystkich nieużywanych profilów użytkowników ze źródła danych aplikacji określonej przez applicationName atrybut w pliku konfiguracji. Użyj parametru , authenticationOption aby określić, czy mają być przeszukiwane tylko profile anonimowe, tylko profile uwierzytelnione, czy wszystkie profile. W przypadku przeszukanych profilów wszystkie profile z elementem występującym LastActivityDate na lub przed zliczeniu określonej userInactiveSinceDate wartości parametru.
