C#中练级orcle数据查询

直接贴代码哈哈哈，

 public DataTable getInfo(int flag)
        {
            OracleConnection conn = null;
            DataSet ds = new DataSet();
            try
            {
                string connString = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.1.10.18)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORCL)));Persist Security Info=True;User ID=zty65;Password=zty65;";
                string sql = "  select * from project where code='19/2015A6150' ";
                conn = new OracleConnection(connString);
                conn.Open();
                OracleCommand cmd = new OracleCommand(sql, conn);
                OracleDataAdapter oda = new OracleDataAdapter(cmd);
                oda.Fill(ds);
                //OracleDataReader ord = cmd.ExecuteReader();
                //while (ord.Read())
                //{
                //    string aa = ord.GetOracleString(0).ToString();
                //    string bb = ord.GetOracleString(1).ToString();
                //    string cc = ord.GetOracleString(2).ToString();
                //    string dd = ord.GetOracleString(3).ToString();
                //}

            }
            catch (Exception)
            {

                Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "msg", "alert('读取数据失败！')", true);
            }
            finally
            {
                //关闭连接
                conn.Close();

            }
            DataTable dt = ds.Tables[];
            return dt;

        }
