问题描述

我知道这是一个简单的问题，我还是个新手。



我想通过刻录2个表来返回数据。 Products表和ProductCategory表。



在我的DAL中，我有一个产品类和一个ProductCategory类。那么我是否必须创建一个具有Products类和Product Category类属性的新类？难道没有其他有效的方法可以做到这一点吗？



我现在在网上搜了一整天，但我找不到答案。如果你能提供一些帮助我会很高兴吗？

I know this is a simple question and I am yet a newbie.

I want to return data by joning 2 tables. "Products" table and "ProductCategory" Table.

In my DAL I have a "Products" class and also a "ProductCategory" class. So do I have to create a new class that has both properties of the Products class and Product Category class? Isn''t there any other efficient way to do that?

I searched the net for a whole day now but i couldn''t find an answer. I would be glad if you can provide some help?

推荐答案

为什么这么复杂？你可以很容易地用两张桌子限制。

据我所知，每件产品都有它自己的产品类别，不是吗？

In因此，您必须向您的'ProductCategory注入额外的属性，例如 List< product>产品< / product> 。

否则，如果 ProductCategory 扮演2个表之间的链接表角色产品和类别，我的回答是YES，你需要创建新的 DTO 将由数据组成的类。

Why so complicated ?? You can easily be bounded only with 2 tables.
As far as i understood every products has it''s own Product category, doesn''t it??
In case of YES, accordingly you must inject additional property to your''s ProductCategory like List<product> Products</product>.
Otherwise, in case where ProductCategory play role of link table between 2 tables Products and Categories, My answer will be YES , you need to create new DTO class which will be consists of data.
