如何实现SignalR显示电子邮件通知到接收者的ASP.NET MVC 4应用

我有一个要求，以显示电子邮件通知使用SignalR接收器。我正在开发使用MVC 4.我是一个初学者，不具备SignalR很多知识我的申请。到目前为止，我已经跟着下面的帖子，试图prepare能满足我的要求的样本。

I have a requirement to show email notification to receivers using SignalR. I am developing my application using MVC 4. I am a beginner and do not have much knowledge for SignalR. So far I have followed the posts below and tried to prepare a sample that can fulfill my requirement.

一个以上是使用knockout.js等不是。我按照这两个，我不能够满足我的要求。

One of above is using knockout.js and other is not. I have followed both and am not able to meet my requirement.

下面是SignalR集线器类code：

Here is the code from SignalR Hub class:

  public void SendEmail(Email email)
        {
            email.SentBy = WebSecurity.CurrentUserId;

            using (NotifyEntities db = new NotifyEntities())
            {
                UsersContext uc = new UsersContext();
                db.Emails.Add(email);
                db.SaveChanges();

                var ret = new
                {
                    Message = post.Message,
                    SentBy = post.SentBy,
                };

                Clients.Caller.sendEmail(ret);


                #region add to table which contain user id and email_post_id (I am sending the email to 2 users/receivers)

                UsersMessage msgRel = new UsersMessage();
                msgRel.EID = email.Id;
                msgRel.UID = 2; //user 1
                db.UsersMessages.Add(msgRel);
                db.SaveChanges();


                msgRel = new UsersMessage();
                msgRel.EID = email.Id;
                msgRel.UID = 5;//user 2
                db.UsersMessages.Add(msgRel);
                db.SaveChanges();

                #endregion


                var unread = (from ure in db.Emails.ToList()
                              join um in db.UsersMessages on ure.Id equals um.EID
                              where um.UID == WebSecurity.CurrentUserId && um.IsReaded == false

                              orderby ure.Id descending

                              select new
                              {
                                  Message = pst.Message,
                                  SentBy = pst.SentBy,
                              }).ToArray();


                Clients.All.loadUnreadPosts(unread); //this returns unread emails of currently logged in user
                Clients.All.loadPosts(ret); // this returns all emails of currently logged in user

            }
        }

当我不使用knockout.js那么我不能够到店即时通知，但只出现在页面刷新并显示给所有用户，而不是接收者。

When I do not use knockout.js then I am not able to shop instant notification, it only appears on page refresh and it display to all users instead of the receivers.

当我使用knockout.js通知会立即显示出，但同样的问题存在消息/通知显示给所有用户。

When I use knockout.js the notification is showing instantly but the same issue exists that message/notification is displaying to all users.

请帮助我。我不知道如何为特定电子邮件的接收者创建组。

Please help me with this. I dont know how to create group for receivers of particular email.
