数据库 数据类型image 应该为二进制

  private DataSet CreateReportDataSet()
        {
            DataSet ds = new DataSet();
            DataTable deliveryorderTable = new DataTable("orderItem");
            deliveryorderTable.Columns.Add(new DataColumn("Image",System.Type.GetType("System.Byte[]"))));        
            deliveryorderTable.Columns.Add(new DataColumn("orderCode"));
            deliveryorderTable.Columns.Add(new DataColumn("receiveShipmentQty"));
            deliveryorderTable.Columns.Add(new DataColumn("reimburseMark"));
            ds.Tables.Add(deliveryorderTable);
            return ds;
        }

dr["image"] = Picture.ImageToBytes(Picture.GetPicBySize(Picture.ReadPicture(0, temp), 200, 300));
