I saw how to send email when the user forgets the password and put up a different code but all gave errors.

I think something was missing and could anyone help me?

follow the codes

 if (txtLogin.Text != "")
        {

            UsuarioDTO objUsuDto = new UsuarioDTO();
            objUsuDto.Login = txtLogin.Text;
            objUsuDto = new UsuarioModel().PesquisarUsuarioLogin(objUsuDto);
            emailUsuarioEnvio = objUsuDto.Email;
            login = objUsuDto.Login;
            senha = objUsuDto.Senha;

            if (emailUsuarioEnvio != "")
            {

// try n1

                //SmtpClient smtp = new SmtpClient("smtp.dominio.com.br", 587);
                //smtp.Credentials = new NetworkCredential("[email protected]","Senha");
                //smtp.EnableSsl = true;
                //MailAddress remetente = new MailAddress("[email protected]");
                //MailAddress destinatario = new MailAddress(emailUsuarioEnvio);


                //MailMessage mensagem = new MailMessage(remetente, destinatario);


                //mensagem.Body = "Seu Login é: "+login + "  Sua senha é: "+senha;
                //mensagem.Subject = "Recuperação de Senha do Sistema
                //NetworkCredential credenciais = new NetworkCredential("[email protected]", "Senha");
                //smtp.Credentials = credenciais;
                //smtp.Send(mensagem);

// another attempt n2

                //System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
                //message.To.Add(emailUsuarioEnvio);
                //message.Subject = "Recuperação de senha do sistema de empilhadeira";
                //message.From = new System.Net.Mail.MailAddress("[email protected]");
                //message.Body = "\n O seu Login é: " + login + "\n A sua senha é: " + senha;
                //System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("mail.dominio.com.br");
                //smtp.Send(message);

// n3 attempt

                SmtpClient cliente = new SmtpClient("mai.dominio.com.br");
                MailMessage Message = new MailMessage();
                Message.From = new MailAddress("[email protected]");
                Message.To.Add(emailUsuarioEnvio);
                Message.Body = "teste de email";
                Message.Subject = "Seja bem Vindo";
                cliente.Credentials = new System.Net.NetworkCredential("[email protected]", "Senha");
                cliente.Port = System.Convert.ToInt32(587);
                cliente.Send(Message);

            }

It would look something like this:

try
        {
            MailMessage mensagem = new MailMessage();
            SmtpClient smtp = new SmtpClient();
            mensagem.From = new MailAddress("[EMAIL AQUI]", "[NOME AQUI]");
            mensagem.To.Add("[EMAIL AQUI]");
            mensagem.Subject = ("[ASSUNTO AQUI]");
            mensagem.Priority = MailPriority.Normal;

            //Configuracao SMTP para HOTMAIL
            smtp.EnableSsl = true;
            smtp.Port = 587;
            smtp.Host = "smtp.live.com";
            smtp.Credentials = new System.Net.NetworkCredential("[EMAIL]", "[SENHA]");
            smtp.Send(mensagem);

        }

catch { }

Watch out for the information you should replace ... There may be some changes to the SMTP configuration portion depending on which server you choose to send.

There's nothing wrong with your last code, you just have to Dispose of SmtpClient . You also do not need to convert the number 587 to integer because it is already an integer. The code I used, copied from yours, and it worked:

using (SmtpClient cliente = new SmtpClient("usuario.dominio.com"))
{
    MailMessage Message = new MailMessage();
    Message.From = new MailAddress("[email protected]");
    Message.To.Add("[email protected]");
    Message.Body = "teste de email";
    Message.Subject = "Seja bem Vindo";
    cliente.Credentials = new System.Net.NetworkCredential("[email protected]", "UMA_SENHA");
    cliente.Port = 587;
    cliente.Send(Message);
}

If all SMTP server data is actually correct (it's worth checking if the server requires SSL and adding cliente.EnableSsl = true; if any), the only thing that could be blocking the sending of your message would be a firewall blocking the port 587. Make sure that on your network port 587 is not blocked, it may be Windows Firewall, a router or even the modem.
