asp.net httpmodule 访问页面控件 备忘

用到的时候发现还得找代码，存一个例子方便自己和他人修改：

using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

namespace FirsteLite.OMS.HttpModule
{
    public class CommonHttpModule : IHttpModule
    {
        #region IHttpModule 成员

        public void Dispose()
        {

        }

        public void Init(HttpApplication context)
        {
            context.PreRequestHandlerExecute += new EventHandler(context_PreRequestHandlerExecute);
        }

        void context_PreRequestHandlerExecute(object sender, EventArgs e)
        {
            if (HttpContext.Current.Handler is Page)
            {
                Page page = (Page)HttpContext.Current.Handler;
                page.PreRender += delegate(object ss, EventArgs ee)
                {
                    //if (page is CDefault)
                    //{
                    //    page.ClientScript.RegisterClientScriptInclude("key", page.ResolveUrl("~/myjs.js"));
                    //}
                    page.Header.Controls.AddAt(0,new Literal {
                        Text = "<meta name="renderer" content="webkit,ie-stand" />" + Environment.NewLine +
                            "<meta http-equiv="X-UA-Compatible" content="chrome=1,IE=8" />" + Environment.NewLine
                    });
                };
            }

        }

        #endregion
    }
}
