Se la creazione dell'utente non riesce MembershipCreateUserException , viene generata un'eccezione.If the user creation fails, a MembershipCreateUserException is thrown. È possibile recuperare un MembershipCreateStatus valore StatusCode dalla proprietà dell'oggetto MembershipCreateUserException che indica il motivo per cui la creazione dell'utente non è riuscita.You can retrieve a MembershipCreateStatus value from the StatusCode property of the MembershipCreateUserException that indicates why user creation failed.

Una volta creato un utente di appartenenza e si dispone di un riferimento a MembershipUser un oggetto per tale utente, è possibile modificare le impostazioni per tale utente con MembershipUser i metodi ChangePasswordQuestionAndAnswer pubblici, ad esempio per le RequiresQuestionAndAnswer applicazioni in cui è trueoppure impostando i valori delle proprietà dell' MembershipUser oggetto e passandoli al UpdateUser metodo.Once a membership user has been created and you have a reference to a MembershipUser object for that user, you can modify the settings for that user with the MembershipUser public methods, such as ChangePasswordQuestionAndAnswer for applications where RequiresQuestionAndAnswer is true, or by setting the property values of the MembershipUser object and passing them to the UpdateUser method.

Se un utente esiste già nell'origine dati per l'applicazione, è possibile ottenere un MembershipUser oggetto per l'utente esistente con il GetUser metodo.If a user already exists in the data source for the application, you can obtain a MembershipUser object for the existing user with the GetUser method.

SqlMembershipProvider Fornisce un'opzione per richiedere un indirizzo di posta elettronica univoco per ogni utente.The SqlMembershipProvider provides an option to require a unique email address for each user. Se la RequiresUniqueEmail proprietà è true, sarà necessario usare uno degli CreateUser overload che consente di specificare un indirizzo di posta elettronica per l'utente che viene creato.If the RequiresUniqueEmail property is true, you will need to use one of the CreateUser overloads that allows you to specify an email address for the user being created. In caso contrario MembershipCreateUserException , verrà generata un'eccezione.Otherwise, a MembershipCreateUserException will be thrown.

CreateUseraggiunge un nuovo utente all'archivio dati e restituisce un MembershipUser oggetto per l'utente appena creato.CreateUser adds a new user to the data store and returns a MembershipUser object for the newly created user. Se la creazione dell'utente non riesce MembershipCreateUserException , viene generata un'eccezione.If the user creation fails, a MembershipCreateUserException is thrown. È possibile recuperare un MembershipCreateStatus valore StatusCode dalla proprietà dell'oggetto MembershipCreateUserException che indica il motivo per cui la creazione dell'utente non è riuscita.You can retrieve a MembershipCreateStatus value from the StatusCode property of the MembershipCreateUserException that indicates why user creation failed.

Una volta creato un utente di appartenenza e si dispone di un riferimento a MembershipUser un oggetto per tale utente, è possibile modificare le impostazioni per tale utente con MembershipUser i metodi ChangePasswordQuestionAndAnswer pubblici, ad esempio per le RequiresQuestionAndAnswer applicazioni in cui è trueoppure impostando i valori delle proprietà dell' MembershipUser oggetto e passandoli al UpdateUser metodo.Once a membership user has been created and you have a reference to a MembershipUser object for that user, you can modify the settings for that user with the MembershipUser public methods, such as ChangePasswordQuestionAndAnswer for applications where RequiresQuestionAndAnswer is true, or by setting the property values of the MembershipUser object and passing them to the UpdateUser method.

Se un utente esiste già nell'origine dati per l'applicazione, è possibile ottenere un MembershipUser oggetto per l'utente esistente con il GetUser metodo.If a user already exists in the data source for the application, you can obtain a MembershipUser object for the existing user with the GetUser method.

Gli spazi iniziali e finali vengono rimossi da tutti i valori dei parametri.Leading and trailing spaces are trimmed from all parameter values.

Esempi

L'esempio di codice seguente crea un nuovo utente per un'applicazione ASP.NET configurata per usare l'autenticazione basata su form e l'appartenenza a ASP.NET.The following code example creates a new user for an ASP.NET application configured to use forms authentication and ASP.NET membership. Se l'utente non viene creato correttamente, viene visualizzato un messaggio all'utente.If the user is not created successfully, a message is displayed to the user. In caso contrario, l'utente viene reindirizzato alla pagina di accesso per l'applicazione.Otherwise, the user is redirected to the login page for the application.

Importante

Questo esempio contiene una casella di testo che accetta l'input dell'utente, che rappresenta una potenziale minaccia per la sicurezza.This example contains a text box that accepts user input, which is a potential security threat. Per impostazione predefinita, le pagine Web ASP.NET verificano che l'input dell'utente non includa script o elementi HTML.By default, ASP.NET Web pages validate that user input does not include script or HTML elements.

CreateUseraggiunge un nuovo utente all'archivio dati e restituisce un MembershipUser oggetto per l'utente appena creato.CreateUser adds a new user to the data store and returns a MembershipUser object for the newly created user. Se la creazione dell'utente non riesce, è possibile MembershipCreateStatus recuperare un valore status dal parametro di output che indica il motivo per cui la creazione dell'utente non è riuscita.If the user creation fails, you can retrieve a MembershipCreateStatus value from the status output parameter that indicates why user creation failed.

Il CreateUser metodo restituirà null se password è una stringa vuota o null, username è una stringa vuota o null contiene una virgola (,), passwordQuestion non null è e è una stringa vuota, oppure passwordAnswer nonnull è e contiene una stringa vuota.The CreateUser method will return null if password is an empty string or null, username is an empty string or null or contains a comma (,), passwordQuestion is not null and is an empty string, or passwordAnswer is not null and contains an empty string.

Dopo aver creato un utente di appartenenza e avere un riferimento a un MembershipUser oggetto per tale utente, è possibile modificare le impostazioni per tale utente con i MembershipUser metodi pubblici e impostare MembershipUser i valori delle proprietà dell'oggetto e quindi passare oggetto per il UpdateUsermetodo. MembershipUserOnce a membership user has been created and you have a reference to a MembershipUser object for that user, you can modify the settings for that user with the MembershipUser public methods and by setting the property values of the MembershipUser object and then passing the MembershipUser object to the UpdateUser method.

Se un utente esiste già nell'origine dati per l'applicazione, è possibile ottenere un MembershipUser oggetto per l'utente esistente con il GetUser metodo.If a user already exists in the data source for the application, you can obtain a MembershipUser object for the existing user with the GetUser method.
