请问，这段代码用户mvc3（razor）模板怎么写？

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<IEnumerable<Model.Sys_Controllers>>"   Theme="base" %>
<script runat="server">   void Page_PreInit()   {   string t = "";
   if (Request.Cookies[User.Identity.Name "Theme"] != null)   {   t = Request.Cookies[User.Identity.Name "Theme"].Value;   }
   if (Request.QueryString["Theme"] != null)   {   t = Request.QueryString["Theme"];   }
   if (!string.IsNullOrEmpty(t))   {   Response.Cookies[User.Identity.Name "Theme"].Value = t;   Response.Cookies[User.Identity.Name "Theme"].Expires = DateTime.Now.AddMonths(1);   this.Page.Theme = t;   }   } </script>

问题补充： 关键是void Page_PreInit()这个在razor模板中不支持。
