DataContext，存储库和工作单元 [英] DataContext, Repositories and Unit of Work

问题描述

我有2个用于2个不同实体的存储库，每个存储库都有自己的专用LINQ-to-SQL DataContext.

I have 2 repositories for 2 different entities and each one has its own private LINQ-to-SQL DataContext.

此外，我有一个服务类，必须从这两个存储库返回结果.

In addition, I have a service class that must return a result from these 2 repositories.

问题1-两个存储库都应该有一个公共的DataContext吗? (我猜想是通过在服务类中实例化一个DataContext并将其注入到2个存储库中来的.)

Question 1 - Should I have a common DataContext for both repositories? (I guess by instantiating a DataContext in the service class and injecting it to the 2 repositories.)

问题2-这是工作单位的目的吗?非常感谢您的帮助.

Question 2 - Is that what the Unit of Work is for? Many thanks for the help.
