在POCO和MVC上使用数据注释进行远程验证 [英] Using Data Annotations on POCO's with MVC for Remote Validation

问题描述

我正在开发ASP.NET MVC应用程序，并且一直在研究在服务层中定义的POCO上使用数据注释.只要我对System.ComponentModel& System.ComponentModel.DataAnnotations没问题，我喜欢它的地方是它允许我在Win Forms应用程序中重用服务层.

I am developing an ASP.NET MVC app and I've been looking into using Data Annotations on my POCO's which are defined in my Service Layer. As long as I have a reference to System.ComponentModel & System.ComponentModel.DataAnnotations this is no problem and what I like about this is that it allows me to reuse my Service Layer in a Win Forms app.

我现在正在寻求使用数据注释进行一些远程验证，并查看了这篇文章:

I'm now looking to do some Remote Validation using Data Annotations and have taken a look at this article: http://msdn.microsoft.com/en-us/library/ff398048(VS.100).aspx

但是，要在这种情况下使用数据注释，我需要引用System.Web.MVC， System.Web和System.Web.Routing.这引入了对Web DLL的依赖性， 在某种程度上限制了我.

However, to use the Data Annotations in this context I need to reference System.Web.MVC, System.Web and System.Web.Routing. This introduces a dependency on the Web DLL's, which limits me somewhat.

任何人都可以推荐一种干净的方法来使用不与ASP.NET MVC结合使用的数据注释来实现远程数据验证，或者可以提出更好的替代方法.

Can anyone recommend a good clean way to implement Remote Data Validation using Data Annotations that isn't coupled with ASP.NET MVC or maybe suggest a better alternative.

感谢您的帮助！

推荐答案

最后，我避免了将DataAnnotations放在POCO上，而是将它们放在ViewModels上，并使用AutoMapper在ViewModel和POCO之间进行映射，从而解决了此问题. (这为我节省了一些乏味的映射时间).在Automapper上有一个很棒的视频， http://perseus.franklins.net/dnrtvplayer /player.aspx?ShowNum=0155

I resolved this in the end by backing away from putting DataAnnotations on my POCO's and instead I put them on my ViewModels and use AutoMapper to Map between my ViewModel and POCO (which saves me some time doing tedious mapping).
