Примеры

В следующем примере кода создается новый пользователь для приложения ASP.NET, настроенного для использования проверки подлинности форм и ASP.NET членства. Если пользователь не создан успешно, отобразится сообщение пользователю. Если пользователь успешно создан, пользователь перенаправляется на страницу входа для приложения. Этот пример кода использует MembershipCreateStatus перечисление для определения сообщения, отображаемого пользователю в случае сбоя.

Перечисление MembershipCreateStatus указывает на успех или сбой попытки создания нового пользователя. CreateUser Если операция завершается ошибкой, MembershipCreateStatus перечисление описывает причину сбоя.

Замечание

Если вы не знакомы с функциями членства ASP.NET, ознакомьтесь с введением в членство , прежде чем продолжить. Список других разделов, связанных с членством, см. в разделе "Управление пользователями с помощью членства".

Если используется перегрузка метода, которая не указывает выходной параметр типаMembershipCreateStatus, неудачная CreateUser попытка создать нового пользователя создает MembershipCreateUserException исключение со StatusCode свойством, заданным для одного из MembershipCreateStatus значений перечисления.
