直接上代码：

一，创建菜单

Action

public ActionResult GetMenu()

        {

            //获取菜单

            List<MenuItem> mainMenu = mm.GetMenuByUser(CurrentUser);

            return PartialView("~/Views/MainPage/GetMenu.cshtml", mainMenu);

        }

View

@model List<BLL.Models.Entitys.MenuItem>

<ul >

    @foreach (var item in Model)

    {

        //target指向 iframe name

        <li><a href="item.菜单路径" target="myFrameName">@item.菜单名称</a></li>

    }

</ul>

二，创建主页面，引用菜单action

<div class="main" id="menu">

        @Html.Action("GetMenu")

            <iframe id="myFrameName" name="myFrameName" frameborder="0" scrolling="auto" width="100%" ></iframe>

    </div>
