根据url地址生成静态页面

最近在做一个新闻系统，前台新闻页面要生成HTML静态页面，
自己找了一些资料，终于达到预期效果
现分享如下：

using System.IO;
using System.Text;
using System.Net;
using System.Configuration;

private void Button1_Click(object sender, System.EventArgs e)
        {
            Encoding code = Encoding.GetEncoding("utf-8");
            StreamReader sr = null;
            StreamWriter sw = null;
            string str = null;

            //读取远程路径
            WebRequest temp = WebRequest.Create(txtUrl.Text.Trim());
            WebResponse myTemp = temp.GetResponse();
            sr = new StreamReader(myTemp.GetResponseStream(), code);
            //读取
            try
            {
                sr = new StreamReader(myTemp.GetResponseStream(), code);
                str = sr.ReadToEnd();

            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                sr.Close();
            }
            string   path   =   HttpContext.Current.Server.MapPath("../news");//取得新闻当前文件夹 
            DateTime   year   =   DateTime.Now;   
            string   years   =   Convert.ToString(year.Year);//当前年   
            string   month   =   Convert.ToString(year.Month);//当前月   
            string   CurrentPath   =   path   +   "/"   +   years;   //设置当前年目录   
  　　                 if(Directory.Exists(CurrentPath)==false)   //若该目录不存在，创建该目录   
  　　　             Directory.CreateDirectory(CurrentPath);   
            string   CurrentMonthPath   =   CurrentPath   +   "/"   +   month;//设置当前月目录   
            if(Directory.Exists(CurrentMonthPath)==false)   //若该目录不存在，创建该目录   
  　　　             Directory.CreateDirectory(CurrentMonthPath);   
            
            string fileName = DateTime.Now.ToString("ddHHmmss") + ".htm";

            //写入
            try
            {
                sw = new StreamWriter(CurrentMonthPath+"/" + fileName, false, code);
                sw.Write(str);
                sw.Flush();

            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                sw.Close();
                Response.Write("恭喜<a href="+CurrentMonthPath+"/" + fileName + " target=_blank>" + fileName + "</a>已经生成，保存在htm文件夹下！");
                Response.Write(CurrentMonthPath+"/"+fileName);
            }

        }
