  4. using System.Web;
  6. namespace SendMailUsingMVC4.Models
  7. {

  9. {
  10. public string To { get; set; }
  11. public string Subject { get; set; }

  13. }
  14. }

  4. using System.Web;
  5. using System.Web.Mvc;
  6. using System.Net.Mail;
  7. using System.IO;
  8. using System.Net;
  9. using SendMailUsingMVC4.Models;
  11. namespace SendMailUsingMVC4.Controllers
  12. {
  13. public class MailMessagingController : Controller
  14. {
  15. //
  16. // GET: /MailMessaging/
  18. public ActionResult Index()
  19. {
  20. return View();
  21. }
  23. [HttpPost]
  24. public ActionResult Index( MyMailModel objModelMail, HttpPostedFileBase fileUploader)
  25. {
  26. if (ModelState.IsValid)
  27. {
  28. string from = "[email protected]"; //any valid GMail ID
  29. using (MailMessage mail = new MailMessage(from, objModelMail.To))
  30. {
  31. mail.Subject = objModelMail.Subject;
  32. mail.Body = objModelMail.Body;
  33. if (fileUploader != null)
  34. {
  35. string fileName = Path.GetFileName(fileUploader.FileName);
  36. mail.Attachments.Add(new Attachment(fileUploader.InputStream, fileName));
  37. }
  38. mail.IsBodyHtml = false;
  39. SmtpClient smtp = new SmtpClient();
  40. smtp.Host = "smtp.gmail.com";
  41. smtp.EnableSsl = true;
  42. NetworkCredential networkCredential = new NetworkCredential(from, "Gmail Id Password");
  43. smtp.UseDefaultCredentials = true;
  44. smtp.Credentials = networkCredential;
  45. smtp.Port = 587;
  46. smtp.Host = "localhost";
  47. smtp.Send(mail);
  48. ViewBag.Message = "Sent";
  49. return View("Index", objModelMail);
  50. }
  51. }
  52. else
  53. {
  54. return View();
  55. }
  56. }
  58. }
  59. }

  8. $(document).ready(function () {
  9. if ('@ViewBag.Message' == 'Sent') {
  10. alert('Mail has been sent successfully');
  11. }
  12. });
  13. </script>
  14. <fieldset>
  15. <legend>Send Email
  16. </legend>
  17. @using (@Html.BeginForm("Index", "MailMessaging", FormMethod.Post, new { @id = "form1", @enctype = "multipart/form-data" }))
  18. {
  19. @Html.ValidationSummary()
  20. <table style="background-color:aliceblue;">
  21. <tr>
  22. <td> To:
  23. </td>
  24. <td>
  25. @Html.TextBoxFor(m => m.To)
  26. </td>
  27. </tr>
  28. <tr>
  29. <td>Subject:
  30. </td>
  31. <td>
  32. @Html.TextBoxFor(m => m.Subject)
  33. </td>
  34. </tr>
  35. <tr>
  36. <td>Attachment
  37. </td>
  38. <td>
  39. <input type="file" name="fileUploader" />
  40. </td>
  41. </tr>
  42. <tr>
  43. <td>Mail Body:
  44. </td>
  45. <td>
  46. @Html.TextAreaFor(m => m.Body)
  47. </td>
  48. </tr>
  49. <tr>
  50. <td></td>
  51. <td>
  52. <input type="submit" value="Send" style="width: 100px;" /></td>
  53. </tr>
