推荐答案

当对LINQ使用3层/层方法时，建议是在数据访问层中使用LINQ数据模型.并在DAL中编写LINQ To SQL方法.

从BLL进行调用以从DAL获取数据并将其传递到UI层.

如果您想使用任何服务公开您的BLL，仍然会遇到麻烦.然后，您必须编写一个Translator服务，该服务将业务实体转换为Data Contracts，反之亦然.


希望对您有所帮助！.

Hi,

While using 3 layer/tier approach with LINQ, the suggestion would be to use LINQ data model in Data access layer. and write the LINQ To SQL methods in DAL.

From BLL make the call to get the data from DAL and pass it on to the UI Layer.

The twist remains, if you want to expose your BLL by using any service. Then you have to write an Translator service which converts business entities into Data Contracts and vice versa.


I Hope this helps!.
