winform连接oracle时Oracle.DataAccess.dll版本有关问题

 protected void Button1_Click(object sender, EventArgs e)
        {
            //OracleConnection con = new OracleConnection("Data Source=(DESCRIPTION =(ADDRESS_LIST =(ADDRESS =(PROTOCOL = TCP)(HOST = ip地址)(PORT = 1521)))( CONNECT_DATA =(SERVICE_NAME = orcl)));User Id=用户名;Password=密码;");
            DbFactory.Init("Data Source=(DESCRIPTION =(ADDRESS_LIST =(ADDRESS =(PROTOCOL = TCP)(HOST = ip地址)(PORT = 1521)))( CONNECT_DATA =(SERVICE_NAME = orcl)));User Id=用户名;Password=密码;", DbTypeEnum.Oracle);
            OracleConnection con = (OracleConnection)DbFactory.GetDbCon();
            con.Open();

            //获取当前运行的dll的版本
            Assembly assembly = Assembly.GetExecutingAssembly();
            Response.Write(con.GetType().Assembly.FullName + "<br/>");
            con.Clone();

            //获取自己封装的数据访问版本
            //DbHelper db = DbFactory.GetInstance();
            //Response.Write(db.GetType().Assembly.FullName + "<br/>");

            ////获取ODP.Net的版本
            //DbConnection cnn = DbFactory.GetDbCon();
            //Response.Write(cnn.GetType().Assembly.FullName + "<br/>");

            //var r = db.ExecuteReader(cnn, CommandType.Text, "select * from BJSW_RSVR_R t");
            //Response.Write(r.HasRows);
            //cnn.Close();

           

            //方式二
            //DbHelper db = DbFactory.GetInstance();
            //var r = db.ExecuteReadEntity<X>(DbFactory.ConnectionString, CommandType.Text, "select * from HY_GPH_A", (reader) =>
            //{
            //    Response.Write(reader.HasRows);
            //    if (reader.Read())
            //    {
            //        List<X> l = new List<X>();
            //        l.Add(new X() { Name = reader[0].ToString() });
            //        return l;
            //    }
            //    else
            //    {
            //        return null;
            //    }
            //});

            //方式三
            //TestDao dao = new TestDao();
            //var list = dao.QueryList();
            //Response.Write(list == null?"没有数据":"有数据");
        }
