关于asp.net生成静态页循环数据的问题
<div class="j_rt2">
<b>{position}</b>
<div class="j_rt2_txt">岗位职责:{duties}
</div>
</div>


我想循环生成这段代码怎么弄啊!现在生成的是数据库中最后一条
cs文件如下:
//这个是一个按钮事件——生成静态页
protected void html_button_Click(object sender, EventArgs e)
  {
  string selete = "select position,duties from news where title='招聘信息'";
  SqlDataAdapter da = new SqlDataAdapter(selete, sqlconn);
  DataSet ds = new DataSet();
  da.Fill(ds);
  string position = ds.Tables[0].Rows[0][0].ToString();
  string duties = ds.Tables[0].Rows[0][1].ToString();
  StringBuilder strHtml = new StringBuilder();
  for (int i = 0; i <= ds.Tables[0].Rows.Count; i++)
  {
  OutputHtml(position, duties);
  }

  }
  private void OutputHtml(string position, string duties)
  {
  string FName = "job.htm";
  string HtmlPath = String.Format(@"/HtmlLink/{0}", FName);
  string HtmlTemp = File.ReadAllText(Server.MapPath("/HtmlTemp/job.htm"), Encoding.UTF8);
  StringBuilder SBuilder = new StringBuilder(HtmlTemp);
  SBuilder.Replace("{position}", position);
  SBuilder.Replace("{duties}", duties);  
  StreamWriter SWriter = File.CreateText(Server.MapPath("/HtmlLink/") + FName);
  SWriter.WriteLine(SBuilder.ToString());
  SWriter.Flush();
  SWriter.Close();  
  }

------解决方案--------------------
把这段代码封装成一个方法,在button_Click事件中循环调用该方法!
------解决方案--------------------
你的stream打开关闭位置不要放到循环体内
代码修改了下,如下:
C# code

        protected void html_button_Click(object sender, EventArgs e)
        {
            string selete = "select position,duties from news where title='招聘信息'";
            SqlDataAdapter da = new SqlDataAdapter(selete, sqlconn);
            DataSet ds = new DataSet();
            da.Fill(ds);
            string position = ds.Tables[0].Rows[0][0].ToString();
            string duties = ds.Tables[0].Rows[0][1].ToString();
            StringBuilder strHtml = new StringBuilder();

            StreamWriter SWriter = File.CreateText(Server.MapPath("/HtmlLink/") + FName);//在写到stream前就打开
            for (int i = 0; i <= ds.Tables[0].Rows.Count; i++)
            {
                OutputHtml(position, duties);
            }
            //全部写完之后再关闭stream
            SWriter.Flush();
            SWriter.Close();

        }
        private void OutputHtml(string position, string duties)
        {
            string FName = "job.htm";
            string HtmlPath = String.Format(@"/HtmlLink/{0}", FName);
            string HtmlTemp = File.ReadAllText(Server.MapPath("/HtmlTemp/job.htm"), Encoding.UTF8);
            StringBuilder SBuilder = new StringBuilder(HtmlTemp);
            SBuilder.Replace("{position}", position);
            SBuilder.Replace("{duties}", duties);
           
            SWriter.WriteLine(SBuilder.ToString());
            
        }
