这是我的试用代码，bapur是使用3层architexture的业务层对象

 Cr_purchaseOrder cr = new Cr_purchaseOrder();
                DataSet ds = new DataSet();
                Bapur = new BAPurchaseOrder();
                Bapur.Condition = "ViewPo";
                Bapur.Code = "PROD00002";

                ds = Bapur.Itemid();


                cr.SetDataSource(ds);

                CrystalReportViewer1.ReportSource = cr;
