I was reading this blog post on ASP.NET MVC 2's new model validation and found it to be pretty cool. I see the value in keeping things DRY by adding a couple attributes to a class property and then automagically getting client and server side validation (as long as your controller checks for valid models).
我正在阅读关于ASP.NET MVC 2的新模型验证的博客文章，并发现它非常酷。通过向类属性添加一些属性然后自动获得客户端和服务器端验证（只要您的控制器检查有效模型），我看到了保持DRY的价值。
That said, imagine an ASP.NET MVC application in a greater context. Perhaps I have an ASP.NET MVC application with this validation and all, but then I want to expose things to new clients, like an iPhone or Android application (not just a mobile browser). I would have to write some web-services or something that use the same underlying repositories/services that my ASP.NET MVC app uses. Could I re-use this validation stuff?
也就是说，想象一下在更大的上下文中的ASP.NET MVC应用程序。也许我有一个带有此验证的ASP.NET MVC应用程序，但后来我想向新客户端公开，比如iPhone或Android应用程序（不仅仅是移动浏览器）。我将不得不编写一些Web服务或使用我的ASP.NET MVC应用程序使用的相同底层存储库/服务的东西。我可以重复使用这个验证的东西吗？
Wouldn't I have to re-write the client-side validation? I don't see a way around this, since I'll be shipping off serialized objects to be de-serialized into non-C# classes from Objective-C or whatever.
我不是必须重新编写客户端验证吗？我没有看到解决这个问题的方法，因为我将从序列化对象发送出去，从Objective-C或其他任何东西反序列化为非C＃类。
Wouldn't I also have to re-write the server-side validation? Is there some way for me to call into the ModelState on an object outside the context of an ASP.NET MVC controller (e.g., as part of the web-services I create to talk to mobile clients).
我不也必须重新编写服务器端验证吗？有没有办法让我在ASP.NET MVC控制器上下文之外的对象上调用ModelState（例如，作为我创建的与移动客户端通信的Web服务的一部分）。

Assuming you are talking about Data Annotations, they are not part of MVC actually. So you can use them elsewhere as you wish.
假设您正在讨论数据注释，它们实际上不是MVC的一部分。所以你可以随意在别处使用它们。
There are other work extending them - annotationscontrib is one of them and I guess you can look at how, for example ModelBinder is implemented and write your own service using that.
还有其他工作可以扩展它们 - annotationscontrib就是其中之一，我想你可以看看如何实现ModelBinder，并使用它来编写自己的服务。
xVal Project is possibly doing along the same lines as what you are after - converting the validation rules into Javascript. Unfortunately I am not sure how much effort you need to adapt xVal for your project or rewrite it.
xVal Project可能与您所使用的相同 - 将验证规则转换为Javascript。不幸的是，我不确定您需要多少努力才能使xVal适应您的项目或重写它。
As for running the validations on the annotated classes one can use the Validator (thanks womp)
至于在带注释的类上运行验证，可以使用Validator（感谢womp）
