菜鸟问题，急求解决,我应该怎么把遍历到的值添加到listbox里面成为一行一行的？
 public static ArrayList SelectF1008_PARADESCByF1008_PARACODE()
        {
            try
            {
                SqlConnection conn = new SqlConnection(DBHelp.conn);
                conn.Open();
                string sql = "select F1008_PARADESC from TB1008_PARAMETER where F1008_PARACODE='壳架等级'";
                SqlCommand comm = new SqlCommand(sql,conn);
                SqlDataReader sdr = comm.ExecuteReader();
               ArrayList list=new ArrayList();
                while(sdr.Read()){

                    PARAMETER parameter = new PARAMETER();
                    parameter.F1008_PARADESC = sdr[0].ToString();
                    string[] strs = parameter.F1008_PARADESC.Split(new char[] { ','});
                    string s = "";
                    foreach (var item in strs)
                    {
                        s += item.ToString();//
                    }
                    list.Add(s);
                }
                return list;
            }
            catch (Exception)
            {
                
                throw;
            }
          
------解决方案--------------------

 foreach (var item in strs)

                    {

                      list.Items.Add(item);

                    }
