生成静态html的问题

我的代码如下：



// 生成静态页

    private void GenerateHTML(string titleid)

    {

        string Bbs_TitleBody = "Bbs_TitleBody_" + titleid.ToString();//缓存名，以分类Id为参数

        Cache.Remove(Bbs_TitleBody);

        DataTable dt = BbsCache.Bbs_GetTitleById(int.Parse(titleid));

        // Response.Write(dt.Rows[0]["title"].ToString());

        string fileyyyymmdd = dt.Rows[0]["fileyyyymmdd"].ToString();

        string filename = fileyyyymmdd + titleid + ".html";

        string caid = dt.Rows[0]["caid"].ToString();

        string caname = ddlXL.SelectedItem.Text;

        string title = dt.Rows[0]["title"].ToString();

        string content = dt.Rows[0]["body"].ToString();

        string time = DateTime.Parse(dt.Rows[0]["createdate"].ToString()).ToShortDateString();

        string username = dt.Rows[0]["username"].ToString();

        string sourceurl = "/forum/Show.aspx?TitleId=" + titleid + "&CaId=" + caid;



        #region 生成静态页

        //创建当前日期的文件夹开始

        string dir = Server.MapPath("~/" + "ITNews/" + fileyyyymmdd);//用来生成文件夹

        if (!Directory.Exists(dir))

        {

            Directory.CreateDirectory(dir);

        }

        //创建当前日期的文件夹结束

        try

        {

            StringBuilder strhtml = new StringBuilder();



            //创建StreamReader对象

            using (StreamReader sr = new StreamReader(Server.MapPath("template.htm"), System.Text.Encoding.Default))

            {

                String oneline;

                //读取指定的HTML文件模板

                while ((oneline = sr.ReadLine()) != null)

                {

                    strhtml.Append(oneline);

                }

                sr.Close();

            }

            //这几个是用来替换的。

            string FilePath = "";

            strhtml = strhtml.Replace("$Title", title);

            strhtml = strhtml.Replace("$NewsCaId", caid);

            strhtml = strhtml.Replace("$NewsCaName", caname);

            strhtml = strhtml.Replace("$Time", time);

            strhtml = strhtml.Replace("$UserName", username);//这里需要循环输出

            strhtml = strhtml.Replace("$Content", content);//这里需要循环输出



            FilePath = Server.MapPath("~/") + "ITNews" + "//" + fileyyyymmdd + "//" + filename;

            strhtml = strhtml.Replace("$SourceURL", sourceurl);



            //创建文件信息对象--------------------------------------------

            FileInfo finfo = new FileInfo(FilePath);

            //以打开或者写入的形式创建文件流

            using (FileStream fs = finfo.OpenWrite())

            {

                //根据上面创建的文件流创建写数据流

                StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.UTF8);

                //把新的内容写到创建的HTML页面中

                sw.WriteLine(strhtml);

                sw.Flush();

                sw.Close();

            }



        }

        catch (Exception ex)

        {

            //输出异常信息

            Response.Write(ex.ToString());

        }



        #endregion

    }
