[How To]如何使用Wildfish进行ISeries开发---多操作篇

            ORDEREntity entity = orderDataSet1.ORDERTable.CreateEntity();
            entity.CUSTOMERNAME = this.txtCustomerName.Text;
            entity.ORDERDATE = DateTime.Now;
            entity.PROCESSDATE = DateTime.Now; //Here I think it will be a nullable date type,but the framework now do not support this feature. 
            entity.PROCESSUSER = "";
            orderDataSet1.ORDERTable.SetEntity(entity);
            ORDERSystem mgrSystem = new ORDERSystem();
            if (!mgrSystem.InsertOrder(orderDataSet1))
            }

1。新建一个Winform 名字是TestMultiTable
2. 添加using
  
using Wildfish.Data.ISeries;
using Wildfish.BusinessFacade.ISeries;
3。画屏幕
4。编写Code
插入OrderItem

 //thus is just a sample,so i do not add lot of validation
            int maxItemIndex = 0;
            for (int i = 0; i < orderDataSet1.ORDERITEMTable.Rows.Count; i++)
            orderDataSet1.ORDERITEMTable.SetEntity(entity);

OrderSystem的InsertOrder逻辑

            KEYSEQNUpdateObject updObj = new KEYSEQNUpdateObject();
            updObj.Where[KEYSEQNUpdateObject.TYPE_Field].FieldValue = "SEQN";
            updObj.Where[KEYSEQNUpdateObject.CODE_Field].FieldValue = "ORDER";
            updObj.Result[KEYSEQNUpdateObject.DETAIL6_Field].Expression = "DETAIL6+1";

            try
            }

代码很简单，我就不细说了，
其实就是，用一个UpdateObject对象生成Key,然后给Order对象的OrderID赋值，然后Insert到数据库。
