在文件上传(下载)成功后向数据库添加上传(下载)记录,可是调试发现该操作执行了两篇,就是向数据添加了两条数据,这样的情况应该怎么样避免,请各大高手指点,小弟有礼了,谢谢了!

protected void Page_Load(object sender, EventArgs e)
{
    try
    {
         if (DownLoadFile(urlPath, strFileName))
         {
              try
              {
                   if(dsAction!=null)
                   {   
                       if (!ts.Contains(ts1))
                       {
                       }
                           
                    }
                    else if(dsAction==null)
                    {
                    }

                    }
               catch (Exception)
               {
               }
           }
      }
      catch (Exception)
      {
      }
}

这个代码会执行两次
