存储ViewBag一个匿名对象 [英] Storing an Anonymous Object in ViewBag

问题描述

这可能是一个愚蠢的问题，但我想的东西，在 ViewBag 一个匿名对象，像这样：

This is probably a silly question, but I am trying to stuff an anonymous object in ViewBag like so:

ViewBag.Stuff = new { Name = "Test", Email = "[e-mail]" };

和来自像这样一个视图访问它：

and access it from a View like so:

@ ViewBag.Stuff.Name

@ViewBag.Stuff.Name

我明白ViewBag是动态的，是东西是一个匿名对象......但是当我看从上面的视图线调试器，我可以看到所有的正确值的属性。为什么模型绑定有这样的困难时期呢？

I understand ViewBag is dynamic and that "Stuff" is an anonymous object... but when I look with the debugger from the View line above, I can see all the properties with the proper values. Why does the model binder have such a hard time with this?

有没有做到这一点，而无需创建模型类的好办法？我想继续使用新{}

Is there a good way to accomplish this without creating a model class? I want to continue using new {}

推荐答案

本质的问题是，匿名类型是内部产生（的见回答），使得硬盘类型引用从视图对象的属性是不可能的。本文提供了一个更详细的解释：

Essentially the issue is that anonymous types are generated as internal (see answer), making hard typed references to the object's property impossible from the View. This article provides a more detailed explanation:

这可能与使用动态匿名包装类（@ Dakill的答案）来完成，但得到丑陋快，应该让程序员问题，为什么他/她会这么做。

It is possible to accomplish with the use of a Dynamic Anonymous wrapper class (@Dakill's answer), but gets ugly fast and should make a programmer question why he/she would do so.
