实体框架和缓存 [英] entity framework and caching

问题描述

嗨！实体框架是否默认缓存数据或者如何工作。例如，如果我有一个gridview，其数据源是我从存储库中提取的对象的集合，那么当我在gridview中通过
分页时，代码是否会触及数据库？因为我正在调用同样的方法，即在gridview的页面索引更改事件上提取数据。感谢您的帮助。

Hi! Does the entity framework cache the data by default or how's that work. For example if i have a gridview whose datasource is a collection of objects that i am pulling from a repository then does the code hit the database againg when I am paging thru the record in gridview? Because I am calling againg that same method that's pulling data on page index changing event of gridview.. Thanks for any help.

推荐答案

对实体框架的查询ObjectContext始终转到数据库。你当然可以在EF之上分层缓存，但它不是内置的。

Queries against the entity framework's ObjectContext always go to the database. You can certainly layer caching on top of the EF, but it is not built in.
