Membership CreateUser

Question

Pessoal,

Estou criando um usuario no membership, porem ocorre o erro "The E-mail supplied is invalid."
O email ta vindo como "[e-mail]".

MembershipUser newUser = Membership.CreateUser(UserName.Text.Trim(), "senhaPadra0");
Roles.AddUserToRole(UserName.Text.Trim(), "Usuarios");

Alem disso, como faco pra checar se o email ja esta cadastrado antes de cria-lo ?

Abracos

Neto se você tenta cadastra um usuário caso o e-mail já exista, o membership dispara um exception, para ser mais especifico o execption MembershipCreateUserException, tente fazer uma rotina parecida com essa para validar este erro:

public void CreateUser_OnClick(object sender, EventArgs args)
{
  try
  {
    // Create new user.

    MembershipUser newUser = Membership.CreateUser(UsernameTextbox.Text, PasswordTextbox.Text);


    // If user created successfully, set password question and answer (if applicable) and 
    // redirect to login page. Otherwise return an error message.

    if (Membership.RequiresQuestionAndAnswer)
    {
      newUser.ChangePasswordQuestionAndAnswer(PasswordTextbox.Text,
                                              PasswordQuestionTextbox.Text,
                                              PasswordAnswerTextbox.Text);
    }

    Response.Redirect("login.aspx");
  }
  catch (MembershipCreateUserException e)
  {
    Msg.Text = GetErrorMessage(e.StatusCode);
  }
  catch (HttpException e)
  {
    Msg.Text = e.Message;
  }
}

public string GetErrorMessage(MembershipCreateStatus status)
{
   switch (status)
   {
      case MembershipCreateStatus.DuplicateUserName:
        return "Username already exists. Please enter a different user name.";

      case MembershipCreateStatus.DuplicateEmail:
        return "A username for that e-mail address already exists. Please enter a different e-mail address.";

      case MembershipCreateStatus.InvalidPassword:
        return "The password provided is invalid. Please enter a valid password value.";

      case MembershipCreateStatus.InvalidEmail:
        return "The e-mail address provided is invalid. Please check the value and try again.";

      case MembershipCreateStatus.InvalidAnswer:
        return "The password retrieval answer provided is invalid. Please check the value and try again.";

      case MembershipCreateStatus.InvalidQuestion:
        return "The password retrieval question provided is invalid. Please check the value and try again.";

      case MembershipCreateStatus.InvalidUserName:
        return "The user name provided is invalid. Please check the value and try again.";

      case MembershipCreateStatus.ProviderError:
        return "The authentication provider returned an error. Please verify your entry and try again. If the problem persists, please contact your system administrator.";

      case MembershipCreateStatus.UserRejected:
        return "The user creation request has been canceled. Please verify your entry and try again. If the problem persists, please contact your system administrator.";

      default:
        return "An unknown error occurred. Please verify your entry and try again. If the problem persists, please contact your system administrator.";
   }
}

Provavelmente já existe um usuario com este e-mail! para criar varios usuários com o mesmo e-mail é prciso 
configurar o web.config assim.

<membership defaultProvider="SqlProvider">
      <providers>
        <add connectionStringName="ConnectionString" applicationName="nome aplicação"
          enablePasswordRetrieval="true" enablePasswordReset="true" requiresQuestionAndAnswer="true"
          requiresUniqueEmail="false" passwordFormat="Encrypted" maxInvalidPasswordAttempts="5"
          minRequiredNonalphanumericCharacters="0" minRequiredPasswordLength="5"
          name="SqlProvider" type="System.Web.Security.SqlMembershipProvider" />
      </providers>
    </membership>

A configuração do membership acima permite ser cadastrado usuários com o mesmo e-mail, agora para verificar se o e-mail já existe eu sugiro que crie uma rotina para verificar na base de dados da tabela membership se já existe o e-mail que esta sendo cadastrdo, essa rotina seria chamada no onchange do campo txt.
