页面代码

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master"

AutoEventWireup="true"
    Inherits="System.Web.Mvc.ViewPage" %>

<%@ Import Namespace="Home.Web.Controllers" %>
<asp:Content ID="indexContent" ContentPlaceHolderID="MainContentPlaceHolder" runat="server">
    <frameset rows="59,*" cols="*" frameborder="no" border="0" framespacing="0">
  <frame src="<%=Url.Action("Top") %>" name="topFrame" scrolling="No" noresize="noresize" id="topFrame" title="topFrame" />
  <frameset cols="213,*" frameborder="no" border="0" framespacing="0">
    <frame src="<%=Url.Action("Left") %>" name="leftFrame" scrolling="No" noresize="noresize" id="leftFrame" title="leftFrame" />
    <frame src="demo/files/editgongnen.htm" name="mainFrame" id="mainFrame" title="mainFrame" />
   
  </frameset>
</frameset>
    <noframes></noframes>
</asp:Content>

后台代码

IUserService _userService = ServiceLocator.Current.GetInstance<IUserService>();
        public ActionResult Index()
        {
            return View("Index");
        }
        public ActionResult Main()
        {
            return View("Main");
        }
        public ActionResult Top()
        {
            return View("Top");
        }
        public ActionResult Left()
        {
            return View("Left");
        }
        public ActionResult Login()
        {
            return View();
        }

但是打开index页面无法打开 left/top/页面。。
