HOw to read the file path,size names if we select directory

if (dirinfo.exists)
  //{
  //    filesinthisfolder = dirinfo.getfiles().count();
  //}
  //if (includesubfolders)
  //{
  //    //filesinthisfolder += dirinfo.getdirectories().sum(di => button1_click(di));
  //    //return filesinthisfolder;
  //}
         
 FileInfo[] filearr = dirinfo.GetFiles();

 foreach (FileInfo f1 in filearr)
 {
   for (int i = 0; i < 1; i++)
   {
     SqlConnection conn = new SqlConnection();

     string name = f1.Name;
     conn = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlCon"].ToString());//Sql database connection written in web.config file
     conn.Open();
     SqlCommand cmd;
     try
     {
     }
