Módulo Smtp com modelo de Html
Todas as vezes que crio um novo projeto que precisa enviar emails acabo indo atrás de projetos anteriores e faço o famoso ctrl+C, ctrl+V mas recentemente cansei desse hábito horrendo e decidi criar uma biblioteca simples que pode ser referenciada em qualquer projeto.
Caso esteja com pressa, baixe a biblioteca aqui, ou o demo completo aqui.
Página do projeto no Github
Para testar o módulo, use Smtp4Dev.
Para começar, criei a classe que gerencia o SmtpClient e SmtpServer:
using System;
using System.Collections.Generic;
using System.Configuration;
using System.IO;
using System.Web.Hosting;
namespace Simple_Mail
{

Mas como também havia interesse em mandar emails em html mais bonitos, usei um modelo do MailChimp™ para ficar mais apresentável. Inclui na pasta de “Email Templates”

Para usar o módulo, instancia-se desta forma
Email _email = new Email(ApplicationType.Web);
string defaultHtml = _email.HTML_CONFIRMATION;
string body = defaultHtml
.Replace("*|EMAIL_PREVIEW|*", "This is a Simple Email")
.Replace("*|HEADER|*", "Simple Email Website")
.Replace("*|FIRSTPARAGRAPH|*", "The message below has been customized")
.Replace("*|SECONDPARAGRAPH|*", Message)
.Replace("*|WEBSITE_URL|*", Request.Url.ToString())
.Replace("*|WEBSITE_NAME|*", _email.WEBSITE_NAME)
.Replace("*|CURRENT_YEAR|*", DateTime.Now.Year.ToString());
_email.SendMail(EmailType.Confirmation, true, body, Email);
Basicamente, está criado um módulo que pode ser reusado em outros projetos, sem o horrendo copy/paste. Claro, melhorias sempre podem ser feitas, por isso o projeto é open source e pode ser baixado do Github.
Para testar a funcionalidade, recomendo usar Smtp4Dev que é bastante prático e não requer nem instalação.
