Exemplos

O exemplo de código a seguir cria um novo usuário para um aplicativo ASP.NET configurado para usar a autenticação de formulários e ASP.NET associação. Se o usuário não for criado com êxito, uma mensagem será exibida para o usuário. Se o usuário for criado com êxito, o usuário será redirecionado para a página de logon do aplicativo. Este exemplo de código usa a MembershipCreateStatus enumeração para determinar a mensagem exibida ao usuário em caso de falha.

Comentários

A MembershipCreateStatus enumeração indica o sucesso ou a falha de uma tentativa de criar um novo usuário. Se a CreateUser operação falhar, a MembershipCreateStatus enumeração descreverá a causa da falha.

Observação

Se você não estiver familiarizado com os recursos de associação do ASP.NET, consulte Introdução à Associação antes de continuar. Para obter uma lista de outros tópicos relacionados à associação, consulte Como gerenciar usuários usando associação.

Se você usar uma CreateUser sobrecarga de método que não especifica um parâmetro de saída do tipo MembershipCreateStatus, uma tentativa malsucedida de criar um novo usuário gera um MembershipCreateUserException com a StatusCode propriedade definida como um dos valores de MembershipCreateStatus enumeração.
