从数据库中读取值并显示在CheckBoxList中

   Tb_ttlsh.Text = drv["SuoShuTaoTiLiuShuiHao"].ToString();
                string zqda = drv["ZhengQueDaAn"].ToString();
                string[] da = zqda.Split(new char[] {',' }); //使用Split()通过逗号将字符串拆分
                foreach (string xx in da)
                {
                    for (int i = 0; i < CBL_da.Items.Count; i++)
                    {
                        if (CBL_da.Items[i].Text == xx)
                        {
                            CBL_da.Items[i].Selected = true;
                        }
                      
                    }
                }
//Tb_ttlsh是TextBox控件,Drv是DataRowView视图对象
