.net_orm_grove的学习（二）

接上篇

  1、插入数据 

  Customers custtomer = new Customers ();
   custtomer.CustomerID="bccu";
   custtomer.CompanyName="bccu";
   custtomer.ContactName="bccu";
   custtomer.ContactTitle="test";
   custtomer.Address="159 hao";
   custtomer.City="bj";
   custtomer.Region="bc";
   custtomer.PostalCode="dds";
   custtomer.Phone="";
   custtomer.Fax="";
   custtomer.Country="china";
   Grove.ORM.ObjectOperator obj=new ObjectOperator(conn);
   obj.Insert(custtomer);
   注：CustomerID不是递增的，所以要在Customers实体类中设置
          [KeyField("CustomerID",KeyType=UniqueIDType.OtherDefinition)]

2、更新数据

   Customers custtomer = new Customers ();
   custtomer.CustomerID="bccu1";
   custtomer.CompanyName="bccu1";
   custtomer.ContactName="bccu1";
   custtomer.ContactTitle="test1";
   custtomer.Address="159 hao1";
   custtomer.City="bj";
   custtomer.Region="bc";
   custtomer.PostalCode="dds";
   custtomer.Phone="";
   custtomer.Fax="";
   custtomer.Country="china";
   Grove.ORM.ObjectOperator obj=new ObjectOperator(conn);
   obj.Update(custtomer,"CustomerID='bccu'");

   3、删除数据

   Grove.ORM.ObjectOperator obj=new ObjectOperator(conn);
   obj.Remove(typeof(Customers),"CustomerID='bccu1'");
