SqlProfileProvider.GetNumberOfInactiveProfiles 方法

定義

取得資料來源中上次活動日期發生在指定的 userInactiveSinceDate 當天或之前的設定檔數目。

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

參數

authenticationOption
ProfileAuthenticationOption

ProfileAuthenticationOption 的其中一個值,指定是否要傳回匿名、已驗證或是這兩種類型的設定檔。

userInactiveSinceDate
DateTime

DateTime,識別哪些使用者設定檔視為非現用。 如果使用者設定檔的 LastActivityDate 發生在這個日期與時間或之前,則會將其視為非使用中設定檔。

傳回

資料來源中上次活動日期發生在指定的日期和時間之前的設定檔數目。
