异步发送电子邮件 [英] Send async e-mails

问题描述

我使用ASP.NET MVC 3 MVCMailer，我尝试使用SendAsync发送电子邮件，但实际上它仍然需要更长的时间。

I am using ASP.NET MVC 3 with MVCMailer, I tried to send e-mails using SendAsync, but actually it still take longer.

所以我试图用Task.Factory像code波纹管：

So I am trying to use Task.Factory like the code bellow:

   var task1 = Task.Factory.StartNew(
            state =>
            {
                var mail = new UserMailer();
                var msg = mail.Welcome("My Name", "[e-mail]");
                msg.SendAsync(); 
            });

   task1.Wait();

问题是，MVCMailer需要HttpContext的，但是这里面的任务，我的HttpContext空。

The problem is, MVCMailer needs HttpContext, but inside this task I got HttpContext Null.

我怎么能发送异步电子邮件？

How can I send Async e-mails?

推荐答案

一个小除了这一点。这里是一个扩展的方法来帮助一些。

A small addition to this. Here is an extension method to help some.

using Mvc.Mailer; 
using System.Threading.Tasks;
public static void SendEmailAsync(this MvcMailMessage msg, HttpContext currContext)
{
      //make this process a little cleaner
      Task.Factory.StartNew(() =>
      {
           System.Web.HttpContext.Current = currContext;
           msg.SendAsync();
       });
}

使用它喜欢沿着从控制器的方法。

Use it like follows from your controller methods.

Mailers.UserMailer um = new Mailers.UserMailer();
um.SendWelcomeEmail(dataObject).SendEmailAsync(ControllerContext.HttpContext.ApplicationInstance.Context);
