帶有電子郵件的 MVC 聯繫表

我想知道是否有人可以幫助送出一個在送出時發送電子郵件的 MVC 聯繫表？我想我已經設置了大多數元素，但由於某種原因，表單似乎正在發送（需要很長時間）然後只是返回到表單並且沒有收到任何電子郵件。

MailModels.cs：

namespace WebApplication1.Models
{
   public class MailModels
   {
      public string Name { get; set; }
      public string Email { get; set; }
      public string Telephone { get; set; }
      public string Message { get; set; }
   }
}

聯繫人.cshtml：

@using (Html.BeginForm("Contact", "Home", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @id = "contact-form", role = "form" }))
{
   @Html.ValidationSummary()
   <fieldset>
       <div class="form-div-1">
           <label class="name">
               @Html.TextBoxFor(m => m.Name, new { @placeholder = "Name *", @type = "text" })
           </label>
       </div>
       <div class="form-div-2">
           <label class="email">
               @Html.TextBoxFor(m => m.Email, new { @placeholder = "Email Address *", @type = "email" })
           </label>
       </div>
       <div class="form-div-3">
           <label class="phone notRequired">
               @Html.TextBoxFor(m => m.Telephone, new { @placeholder = "Telephone Number", @type = "text" })
           </label>
       </div>
       <div>
           <label class="message">
               @Html.TextAreaFor(m => m.Message, new { @placeholder = "Message *" })
           </label>
       </div>
       <div class="button-wrapper">
           <input type="submit" value="Send" name="submit" class="button"> <input type="reset" value="Reset" name="MFReset" class="button"><span>* Required Fields</span>
       </div>
   </fieldset>
}

HomeController.cs：

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net.Mail;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Html;
using WebApplication1.Models;
using System.Text;

namespace WebApplication1.Controllers
{
   public class HomeController : Controller
   {
   public ActionResult Contact()
   {
       ViewBag.Message = "Test Form";

       return View();
   }

   [HttpPost]
   public ActionResult Contact(MailModels e)
   {
       if (ModelState.IsValid)
       {

           StringBuilder message = new StringBuilder();
           MailAddress from = new MailAddress(e.Email.ToString());
           message.Append("Name: " + e.Name + "\n");
           message.Append("Email: " + e.Email + "\n");
           message.Append("Telephone: " + e.Telephone + "\n\n");
           message.Append(e.Message);

           MailMessage mail = new MailMessage();

           SmtpClient smtp = new SmtpClient();

           smtp.Host = "smtp.mail.yahoo.com";
           smtp.Port = 465;

           System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("yahooaccount", "yahoopassword");

           smtp.Credentials = credentials;
           smtp.EnableSsl = true;

           mail.From = from;
           mail.To.Add("yahooemailaddress");
           mail.Subject = "Test enquiry from "+e.Name;
           mail.Body = message.ToString();

           smtp.Send(mail);
       }
       return View();
   }

用這個把我的頭撞在磚牆上，任何幫助將不勝感激:-)

發送電子郵件需要時間。它應該是一個執行緒。把你的程式碼放在一個函式中。並進行以下更改：

public void SendEmail(string toAddress, string fromAddress, 
                     string subject, string message)
{
   try
   {
       using (var mail = new MailMessage())
       {
           const string email = "username@yahoo.com";
           const string password = "password!";

           var loginInfo = new NetworkCredential(email, password);


           mail.From = new MailAddress(fromAddress);
           mail.To.Add(new MailAddress(toAddress));
           mail.Subject = subject;
           mail.Body = message;
           mail.IsBodyHtml = true;

           try
           {
               using (var smtpClient = new SmtpClient(
                                                "smtp.mail.yahoo.com", 465))
               {
                   smtpClient.EnableSsl = true;
                   smtpClient.UseDefaultCredentials = false;
                   smtpClient.Credentials = loginInfo;
                   smtpClient.Send(mail);
               }

           }

           finally
           {
               //dispose the client
               mail.Dispose();
           }

       }
   }
   catch (SmtpFailedRecipientsException ex)
   {
       foreach (SmtpFailedRecipientException t in ex.InnerExceptions)
       {
           var status = t.StatusCode;
           if (status == SmtpStatusCode.MailboxBusy ||
               status == SmtpStatusCode.MailboxUnavailable)
           {
               Response.Write("Delivery failed - retrying in 5 seconds.");
               System.Threading.Thread.Sleep(5000);
               //resend
               //smtpClient.Send(message);
           }
           else
           {
               Response.Write("Failed to deliver message to {0}",
                                 t.FailedRecipient);
           }
       }
   }
   catch (SmtpException Se)
   {
       // handle exception here
       Response.Write(Se.ToString());
   }

   catch (Exception ex)
   {
       Response.Write(ex.ToString());
   }

}

在控制器中呼叫該函式：

[HttpPost]
public ActionResult Contact(MailModels e)
{
   if (ModelState.IsValid)
   {

       //prepare email
       var toAddress = "someadress@yahoo.co.uk";
       var fromAddress = e.Email.ToString();
       var subject = "Test enquiry from "+ e.Name;
       var message = new StringBuilder();
       message.Append("Name: " + e.Name + "\n");
       message.Append("Email: " + e.Email + "\n");
       message.Append("Telephone: " + e.Telephone + "\n\n");
       message.Append(e.Message);

       //start email Thread
       var tEmail = new Thread(() => 
      SendEmail(toAddress, fromAddress, subject, message));
       tEmail.Start();
   }
   return View();
}

如果您沒有收到電子郵件，請檢查您的垃圾郵件文件夾
