ViewData的使用

    //Controller
       public ActionResult Index()
        {
            ViewData["Message"] = "欢迎使用 ASP.NET MVC!";
            List<string> list= new List<string>();
            list.Add("test1");
            list.Add("test2");
            ViewData["list"] = list;

            Models.User user = new Models.User();
            user.ID = 100;
            user.Name = "ZG";
            ViewData["User"] = user;
            return View();
        }

     <%= Html.Encode(ViewData["Message"]) %></h2>
    <%foreach (var item in ViewData["list"] as List<string>) %>
    <% { %>
    <% =item %>
    <%} %>
    <br />
    <% var user = ViewData["User"] as MvcDemo.Models.User;%>
    <%=user.Name%>
    <%=user.ID%>
