ASP.NET MVC 動態設定模板

在頁面中添加如下代碼（Page_PreInit事件代碼中動態設定模板，前提是在頁面Action中將使用者資訊存到ViewData["USER"]了）：

    <script runat="server">        //動態設定模板        protected void Page_PreInit(object sender, EventArgs e)        {            switch (ViewData.Eval("USER.roleid").ToString())            {                case "1": this.Page.MasterPageFile = "~/Views/Shared/SuperAdmin.Master";                    break;                case "2": this.Page.MasterPageFile = "~/Views/Shared/Manager.Master";                    break;                default: this.Page.MasterPageFile = "~/Views/Shared/Default.Master";                    break;            }        }    </script>
