public:
 MembershipCreateUserException();

public MembershipCreateUserException();

Public Sub New ()

Exemplos

O exemplo de código seguinte chama o Membership.CreateUser método para criar um novo utilizador de membro. Se a criação do utilizador falhar, a MembershipCreateUserException é lançada.

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

  If u Is Nothing Then
    Throw New MembershipCreateUserException()
  End If

  Return u
End Function
