此处的代码用于检查datagridview（productGridView）中添加的药物之间是否存在任何相互作用
- 前端：c＃with vs2012 .net 4.0
- 后端：SQL Server紧凑型版4.0
数据库的架构：
-
表产品：productid;名称
-
表product_druginteractionClass：productid;duginsionctionClassid
-
表相互作用：相互作用;duginInteractionClassid1;
duginsionctionClassid2;风险对 -
table drugIntractionClass：drugInteractionClassid;名称
许多产品可以具有相同的药物相互作用类别
方法是：
- 循环投掷 productGridView 基于 productid 基于 name 然后根据 productid 选择 druginteractionClassID 然后将结果放入另一个datagridview（ listClassification ）
- 从dataGridView（ listClassification ）中创建2个数据中的数据列表///在这里显示一个小问题，因为列表保留了相同的所有药物互动class数字，并且将它们丢弃了双重迭代测试组合互动////如何以编程方式创建单独的列表，而我不知道会添加多少药物？
- 循环投掷2个列表，并根据组合选择互动，并加入结果，并加入毒品互动类名称
是否可以动态创建列表并将其扔到 组合虽然不知道在运行时间之前列出多少列表？
我也想在交互中循环循环，并检查如果不删除不适当的交互，是否重复了产品。
- 可能全部可以在一个查询中总结一个（选择选择的选择）？
实际上我是药学专业的学生（我只是喜欢编码并且不做得很好，我什至没有完成任何C＃在C＃/sql/ado.net之间的600页左右，所以对不起）
