Alcune informazioni sono relative alla release non definitiva del prodotto, che potrebbe subire modifiche significative prima della release definitiva. Microsoft non riconosce alcuna garanzia, espressa o implicita, in merito alle informazioni qui fornite.

Recupera i dati dei profili utente in cui la data dell'ultima attività corrisponde o è precedente alla data e all'ora specificate.

public:
 override System::Web::Profile::ProfileInfoCollection ^ GetAllInactiveProfiles(System::Web::Profile::ProfileAuthenticationOption authenticationOption, DateTime userInactiveSinceDate, int pageIndex, int pageSize, [Runtime::InteropServices::Out] int % totalRecords);

public override System.Web.Profile.ProfileInfoCollection GetAllInactiveProfiles (System.Web.Profile.ProfileAuthenticationOption authenticationOption, DateTime userInactiveSinceDate, int pageIndex, int pageSize, out int totalRecords);

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

Public Overrides Function GetAllInactiveProfiles (authenticationOption As ProfileAuthenticationOption, userInactiveSinceDate As DateTime, pageIndex As Integer, pageSize As Integer, ByRef totalRecords As Integer) As ProfileInfoCollection

Parametri

authenticationOption: ProfileAuthenticationOption

Uno dei valori dell'enumerazione ProfileAuthenticationOption che specifica se vengono restituiti profili di tipo anonimo, autenticato o entrambi.

userInactiveSinceDate: DateTime

Oggetto DateTime che identifica i profili utente considerati inattivi. Se il valore specificato nella proprietà LastActivityDate di un profilo utente corrisponde o è precedente alla data e all'ora specificate in questo parametro, il profilo viene considerato inattivo.

pageIndex: Int32

Indice della pagina di risultati da restituire. pageIndex è in base zero.

pageSize: Int32

Dimensione della pagina di risultati da restituire.

totalRecords: Int32

Quando termina, il metodo contiene un intero che identifica il numero totale di profili. Questo parametro viene passato non inizializzato.

Restituisce

ProfileInfoCollection

Un oggetto ProfileInfoCollection che contiene le informazioni sui profili utente inattivi.

Eccezioni

ArgumentException

pageIndex è minore di zero.

-oppure-

pageSize è minore di 1.

-oppure-

pageIndex moltiplicato per pageSize è maggiore di Int32.MaxValue.

Esempio

Nell'esempio di codice seguente viene illustrata una pagina ASP.NET che gestisce i profili inattivi. Viene fornito un pulsante per eliminare tutti i profili inattivi. Se un profilo viene considerato inattivo è basato sulla data specificata per il userInactiveSinceDate parametro.

Commenti

Il GetAllInactiveProfiles metodo viene usato per recuperare le informazioni sul profilo dall'origine dati per i profili utente inutilizzati per l'applicazione specificata dall'attributo applicationName nel file di configurazione. Usare il authenticationOption parametro per specificare se si desidera eseguire la ricerca solo profili anonimi, solo profili autenticati o tutti i profili. Dei profili di ricerca, qualsiasi profilo con un LastActivityDate oggetto che si verifica prima della restituzione del valore del parametro specificato userInactiveSinceDate .

I risultati restituiti da sono vincolati dai GetAllInactiveProfilespageIndex parametri e pageSize . Il pageSize parametro identifica il numero massimo di ProfileInfo oggetti da restituire in ProfileInfoCollection. Il pageIndex parametro identifica la pagina dei risultati da restituire. 0 identifica la prima pagina. Il totalRecords parametro è un out parametro impostato sul numero totale di profili utente inattivi per il parametro configurato applicationNamein base authenticationOption ai parametri e userInactiveSinceDate . Ad esempio, se sono presenti 13 utenti per l'oggetto configurato applicationNamee il valore è 1 con un pageSize valore pari a 5, il ProfileInfoCollectionpageIndex valore restituito conterrà il sesto fino al decimo profili inattivi. Il totalRecords parametro verrà impostato su 13.
