ADO.net 中的LISTVIEW 控件 在连接SQL2005 时 ， 两个字符串怎样相关联？

Question

private void AddDataToList()
        {
            this.lstview.Items.Clear();            DataBase db = new DataBase();
            string sql = "......";
            DataTable dt = db.Select(sql);
            if (dt != null)
            {
                foreach (DataRow dr in dt.Rows)
                {
                    ListViewItem lst = new ListViewItem();
                    lst.Text = dr[0].ToString();
                    lst.SubItems.Add(dr[1].ToString());
                    lst.SubItems.Add(dr[2].ToString());
                    lst.SubItems.Add(dr[3].ToString());
                    lst.SubItems.Add(dr[4].ToString());
                    lst.SubItems.Add(dr[5].ToString());
                    lst.SubItems.Add(dr[6].ToString());
                    lst.SubItems.Add(dr[7].ToString());
                    lst.SubItems.Add(dr[8].ToString());
                    lst.SubItems.Add(dr[9].ToString());
                    lst.SubItems.Add(dr[10].ToString());
                    lst.SubItems.Add(dr[11].ToString());
                    lst.SubItems.Add(dr[12].ToString());
                    lst.SubItems.Add(dr[13].ToString());
                    lst.SubItems.Add(dr[14].ToString());//有多少列则添加多少子项
                    this.lstview.Items.Add(lst);
                }
            }
        }
