Esempio

Nell'esempio di codice seguente viene chiamato il Membership.CreateUser metodo per creare un nuovo utente di appartenenza. Se la creazione dell'utente ha esito negativo, viene generata una MembershipCreateUserException classe.

public MembershipUser MyCreateUser(string username, string password, string email,
                                   string question, string answer)
{
  MembershipCreateStatus status;

  MembershipUser u = Membership.CreateUser(username, password, email, question, 
                                           answer, true, out status);
  if (u == null)
  {
    throw new MembershipCreateUserException();
  }

  return u;
}

Public Function MyCreateUser(username As String, password As String, email As String, _
                             question As String, answer As String) As MembershipUser

  Dim status As MembershipCreateStatus

  Dim u As MembershipUser = Membership.CreateUser(username, password, email, question, _
                                                  answer, True, status)
  If u Is Nothing Then
    Throw New MembershipCreateUserException()
  End If

  Return u
End Function

Commenti

Commenti

La MembershipCreateUserException classe viene generata dal Membership.CreateUser metodo quando l'utente non viene creato.

È possibile usare il message parametro per impostare la Message proprietà dell'eccezione su una descrizione significativa del motivo dell'eccezione.

La MembershipCreateUserException classe viene generata dal Membership.CreateUser metodo quando l'utente non viene creato.

Il statusCode parametro consente di indicare il motivo per cui è MembershipCreateUserException stato generato. Il valore del statusCodeStatusCode parametro viene esposto dalla proprietà .

Parametri

Esempio

Nell'esempio di codice seguente viene illustrata un'implementazione della MembershipCreateUserException classe che chiama il costruttore protetto della classe base con le informazioni e il contesto di serializzazione forniti.

using System.Web.Security;
using System.Runtime.Serialization;

public sealed class MyCreateUserException : MembershipCreateUserException
{
  public MyCreateUserException(SerializationInfo info, StreamingContext context) : base(info, context)
  {
  }
}

Imports System.Web.Security
Imports System.Runtime.Serialization

Public NotInheritable Class MyCreateUserException
  Inherits MembershipCreateUserException

  Public Sub New (info As SerializationInfo, context As StreamingContext)
    MyBase.New(info, context)
  End Sub
End Class

Commenti

Questo costruttore viene chiamato durante la deserializzazione per ricostituire l'oggetto dell'eccezione trasmesso tramite un flusso. Per altre informazioni, vedere Serializzazione XML e SOAP.

Parametri

Esempio

Nell'esempio di codice seguente viene chiamato il CreateUser metodo per creare un nuovo utente di appartenenza. Se la creazione dell'utente ha esito negativo, viene generata una MembershipCreateUserException classe. Se l'eccezione non è un MembershipCreateUserExceptionoggetto , viene specificata l'eccezione rilevata come oggetto InnerException generato MembershipCreateUserException .

public MembershipUser MyCreateUser(string username, string password, string email)
{
  MembershipUser u = null;

  try
  {
    u = Membership.CreateUser(username, password, email);
  }
  catch (MembershipCreateUserException e)

  }
  catch (Exception e)
  {  
    throw new MembershipCreateUserException("An exception occurred creating the user.", e);
  }

  Dim u As MembershipUser = Nothing

    u = Membership.CreateUser(username, password, email)
  Catch e As MembershipCreateUserException
    Throw e
  Catch e As Exception  
    Throw New MembershipCreateUserException("An exception occurred creating the user.", e)
  End Try

  Return u
End Function

Commenti

Un'istanza della MembershipCreateUserException classe viene generata dal Membership.CreateUser metodo quando l'utente non viene creato.

È possibile usare questo overload del MembershipCreateUserException costruttore per fornire informazioni su un'eccezione rilevata che si è verificata durante la creazione dell'utente.
