使用动态类型MVC强类型的视图 [英] using dynamic as type of MVC strongly typed view

问题描述

我有一个网页，创造动态的实体。

I have a page for creation of dynamic entities.

<%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
...

我有两个动作：

public ActionResult Create()
  {
      dynamic model = ...
      return View(model);
  }

[HttpPost]
public ActionResult Create(dynamic(1) entity)
  {
     ...      
  }

好了，问题是，实体来空从页面。如果我改变动态（1）真正的类型，它工作正常。

Well, the problem is that the entity comes empty from the page. If I change dynamic in (1) for the real type it works fine.

推荐答案

我不是100％，但我认为问题是，默认的模型绑定不知道该怎么做了动态类型，因为它不具有任何限定特性反映过来。你需要编写自己的模型绑定，将使用表单输入名称代替，这是很危险的/不可靠的，因为表格可在客户端进行修改。

I'm not 100% on this, but I think the problem is that the default model binder has no idea what to do with a 'dynamic' type, since it doesn't have any defined properties to reflect over. You'd need to write your own model binder that would use the form input names instead, which is dangerous/unreliable because the form can be modified on the client side.

我以前探索（这里所以实际上动态类型ViewPages：<一href=\"http://stackoverflow.com/questions/1178984/dynamic-typed-viewpage\">http://stackoverflow.com/questions/1178984/dynamic-typed-viewpage),和我来，它真的不给你在大多数情况下任何结论。至少，目前还没有（MVC 3+可能是不同的故事）。

I've explored dynamically-typed ViewPages before (here on SO actually: http://stackoverflow.com/questions/1178984/dynamic-typed-viewpage), and I've come to the conclusion that it really doesn't give you anything in most situations. At least, not yet (MVC 3+ could be different story).
