将自定义 ValueProviderFactories 添加到 ASP.NET MVC3？
我试图尝试将 Protobuf ValueProviderFactory 添加到 MVC3，以便我可以选择 MIME 类型并将原始数据反序列化为操作参数的对象。我还可以使用它来更改默认的 Json 序列化器。
查看 JsonValueProviderFactory.cs，这应该不会太困难，但工厂似乎都是硬编码的。
对于 Protobuf，我也许可以使用 IValueProvider 做一些事情，但我什至还没有检查 MVC3 在收到 MIME 类型的 application/x-protobuf 时会做什么。
我以正确的方式处理这件事吗？
更新
我发现这篇博客文章其中讨论了创建 IValueProvider。然后它在底部提到这在 MCV2 周围发生了变化。他将其更改为 ValueProviderFactory 并调用：
ValueProviderFactories.Factories.Add(new HttpCookieValueProviderFactory());
但在 MVC3 中此属性是只读的。
I was looking to try and add a Protobuf ValueProviderFactory to MVC3 so that I could pick out the MIME type and deserialize the raw data into objects for action parameters. I could also use this to change the default Json serializer.
Looking at JsonValueProviderFactory.cs this shouldn't be too difficult, but the factories all appear to be hard-coded.
For Protobuf I may be able to do something with an IValueProvider but I haven't even checked yet what MVC3 does when it recieves an MIME type of application/x-protobuf.
Am I going about this the right way?
UPDATE
I found this blog post that talks about creating an IValueProvider. It then mentions at the bottom that this changed around MCV2. He changed it to a ValueProviderFactory and calls :
ValueProviderFactories.Factories.Add(new HttpCookieValueProviderFactory());
But in MVC3 this property is read only.

事实证明它不是只读的，您可以按如下方式添加提供程序：
如果我自己检查的话我就会知道这一点！
我今天做了更多搜索，这篇博客文章似乎表明
DependencyResolver将找到继承ValueProviderFactory的任何类。我使用 MEF 进行依赖项解析，因此我只需添加一个 Export 属性，它就会被自动选取。我现在有一个进一步的问题为protobuf-net编写自定义ValueProviderFactory 。
It turns out that it is not read only and you can add providers as follows:
I would have know this had I checked myself!
I've done some more searching today, and this blog post seems to suggest that the
DependencyResolverwill find any classes that inheritValueProviderFactory. I'm using MEF for dependency resolution so I can just add an Export attribute and it'll get picked up automatically.I now have a further issue writing a custom ValueProviderFactory for protobuf-net.
