数据库读取指定数组集

public void dbOpen()        {            //定义连接数据库变量            SqlConnection dsConn = new SqlConnection                ("server=192.168.31.245;uid=sa;pwd=xxx;database=news");            dsConn.Open();                        //定义DataSet对象            DataSet DS = new DataSet();                        //定义SqlDataAdapter对象            SqlDataAdapter MyCommand = new SqlDataAdapter("select * from RTO_Commen", dsConn);                      //将前端name1赋值单个记录集            name1.Text = (string)DS.Tables[0].Rows[1]["D_Name"];                             dsConn.Close();        }
