Answer 3

可以新建一个 page基类, 把常用的代码方法，写在这个类中 如下： public class BasePage : System.Web.UI.Page
    {
        public BasePage()
            : base()
        { }
        protected override void Render(HtmlTextWriter writer)
        {
            if (writer is System.Web.UI.Html32TextWriter)
            {
                writer = new FormFixerHtml32TextWriter(writer.InnerWriter);
            }
            else
            {
                writer = new FormFixerHtmlTextWriter(writer.InnerWriter);
            }
            base.Render(writer);
        }
        /// <summary>
        /// 弹出消息框并且转向到新的URL
        /// </summary>
        /// <param name="message">消息内容</param>
        /// <param name="toURL">连接地址</param>
        public void AlertAndRedirect(string message, string toURL)
        {            string js = "<script language=javascript>alert('{0}');window.location.replace('{1}')</script>";
            HttpContext.Current.Response.Write(string.Format(js, message, toURL));        }
       
        protected override void SavePageStateToPersistenceMedium(object state)
        {
            string value = new ObjectStateFormatter().Serialize(state);
            string viewStateID = (DateTime.Now.Ticks + (long)this.GetHashCode()).ToString(); //产生离散的id号码
            string fn = Path.Combine(this.Request.PhysicalApplicationPath, @"~/App_Data/ViewState/" + viewStateID);
            //ThreadPool.QueueUserWorkItem(File.WriteAllText(fn, value));
            File.WriteAllText(fn, value);
            Cache.Insert(viewStateID, value);
            base.SavePageStateToPersistenceMedium(viewStateID);
        }
       */  
        public void PageAlert(string key, string message)
        {
            message = DeleteUnVisibleChar(message);
            string js = @"<Script language='JavaScript'>
            alert('" + message + "');</Script>";
            Page.RegisterStartupScript(key, js);
        }
        // 弹出窗口信息，并关闭
        public void AlertAndClose(string key, string message)
        {
            message = DeleteUnVisibleChar(message);
            string js = @"<Script language='JavaScript'>
            alert('" + message + "');window.close();</Script>";
            Page.RegisterStartupScript(key, js);
        }
        // 删除不可见字符
        public string DeleteUnVisibleChar(string sourceString)
        {
            System.Text.StringBuilder sBuilder = new System.Text.StringBuilder(131);
            for (int i = 0; i < sourceString.Length; i++)
            {
                int Unicode = sourceString[i];
                if (Unicode >= 16)
                {
                    sBuilder.Append(sourceString[i].ToString());
                }
            }
            return sBuilder.ToString();
        }
        //转到链接页
        public void URLTo(string url, string target)
        {
            Response.Write("<script>window.open('" + url + "','" + target + "');</script>");
        }
       ...............其它页面 改一下 继承这个页面，就可以继承里面的方法
如下：public partial class bbs_TopicDetail : BasePage
{
    protected void Page_Load(object sender, EventArgs e)
    {
                    
     }
    //提交回复
    protected void imgReply_ServerClick(object sender, ImageClickEventArgs e)
    {
        if (CheckLogin() == true)
        {
            string username = GetUserName();
            UserID = userbll.GetIdByUname(username);
        }
        else
        {
            //AlertAndRedirect("请登录", "../Login.aspx");
            PageAlert("", "请登录");  //基类方法
            return;
        }
        if (Request.Form.Get("hiddenTestN").Equals(GetToken()))
        {
            if (txtEditor.Value.Trim().Length < 5 || txtEditor.Value.Trim().Length > 2000)
            {
                PageAlert("notComment1", "回复字数不要少于5字符或大于2000字符！");//基类方法                return;
            }
            string ReplyContent = getSpecialCharUBB(txtEditor.Value.ToString());
            string ip = GetRealIP();
            topicbll.ReplyTopicById(TopicId, UserID, ReplyContent, ip);
            GetReplyTopic(TopicId);
            txtEditor.Value = null;
            SetToken();//别忘了最后要更新Session中的标志   
        }
        else
        {
            PageAlert("", "重复提交");//基类方法        }  
    }
