Using a dynamic type type with a typical MVC type

Question

I have a page for creating dynamic objects.

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

I have two actions:

 public ActionResult Create() { dynamic model = ... return View(model); } [HttpPost] public ActionResult Create(dynamic(1) entity) { ... } 

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

Answer 1

I’m not 100% at that, but I think that the problem is that by default the connecting device has no idea what to do with the “dynamic” type, since it does not have any specific properties for reflection. You will need to write your own middleware that will use the form input names, which is dangerous / unreliable because the form can be modified on the client side.

I have studied dynamically typed ViewPages before (here on SO actually: Dynamically typed ViewPage ), and I came to the conclusion that it really doesn't give you anything in most situations. At least not yet (MVC 3+ may be different history).

And here are some notes from Phil Haack on this subject: http://haacked.com/archive/2009/08/26/method-missing-csharp-4.aspx
