实体框架和DTO [英] Entity Framework and DTO

问题描述

林计划使用的EF（POCO）产生的实体在将数据发送到客户端，而不是创建的DTO？这是一个好的做法呢？基本上，我的EDMX文件是我的DAL层上。
所以UI会对我DAL直接访问。谢谢你。

Im planning to use the Entities generated by the EF (POCO) in sending data to the client instead of creating DTOs? Is this a good practice? Basically, my EDMX file is on my DAL layer. So the UI will have direct access on my DAL. Thanks.

推荐答案

基本上，我不认为这是DAL对象发送到你的界面是一个好主意，所以我会用DTO的。为了尽量减少努力这样做我会以看一看的 DTO发电机，生成DTO的代码，让您从DAL对象转换为DTO，反之亦然。

Basically, I don't think it's a good idea to send DAL objects to your interface, so I would use DTOs. To minimize the effort doing so I would take a look at an DTO generator, to generate DTO code which lets you convert from DAL object to DTO and vice versa.

编辑：对不起，没看到你正在使用POCO。看看这个 SO帖子

Sorry, didn't see you are using POCO. Have a look at this SO post
