客车网上销售系统之订单统计和销售情况管理

1、今日完成任务:
(1)后台订单统计功能
(2)后台销售情况查询
2、核心源码:

后台订单统计代码：

 /// <summary>
        /// 订单统计
        /// </summary>
        /// <returns></returns>
        public ActionResult Index(string TicketName="")
        {
            if (Session["userID"] == null)
            {
                return RedirectToAction("Index", "Login");
            }
            var list = (from a in db.OrderInfo
                        group a by a.TicketID
                        into g
                        select new
                        {
                            g.Key,
                            TotalPrice = g.Sum(a => a.OrderPrice),
                            OrderCount = g.Count()
                        }).ToList();
            dynamic data = list.Select(s => Tuple.Create(s.Key, s.OrderCount, s.TotalPrice, db.Ticket.Find(s.Key).StartStation, db.Ticket.Find(s.Key).EndStation, db.Ticket.Find(s.Key).TicketPrice, db.Ticket.Find(s.Key).TicketName)).Where(aa=>aa.Item7.Contains(TicketName));
            ViewData["data"] = data;
            return View();
        }

后台订单统计前台页面代码：

@using OnlineTicketSystem.Models;

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
    dynamic dd = ViewData["data"];
}
<script type="text/javascript">
    $(function () {
        $("#nav .nav #li0").addClass("active").siblings().removeClass("active");
    });
</script>


<div class="container">

3、遇到的问题:
(1)控制器向视图传递匿名对象不太会
4、解决的方法:
(1)去网上找了找资料，用dynamic实现了效果
具体方法如下：

控制器代码：

 dynamic data = list.Select(s => Tuple.Create(s.Key, s.OrderCount, s.TotalPrice, db.Ticket.Find(s.Key).StartStation, db.Ticket.Find(s.Key).EndStation, db.Ticket.Find(s.Key).TicketPrice, db.Ticket.Find(s.Key).TicketName)).Where(aa=>aa.Item7.Contains(TicketName));
            ViewData["data"] = data;

视图代码：

  @{
                foreach (var item in dd)
                {
                        <tr>
                            <td>@item.Item7</td>
                            <td>@item.Item4<span>-></span>@item.Item5</td>
                            <td>￥@item.Item6</td>
                            <td>@item.Item2</td>
                            <td>￥@item.Item3</td>
                            <td>@Html.ActionLink("查看销售情况", "SalesIndex", new { oid = item.Item1 })</td>
                        </tr>
                    }
                
            }
