具有匿名类型模型类的剃刀视图。有可能的？

I want to create a view using razor template, but I do not want to write a class for model, because in many views i will have many queries which will be returning diferent models.

我想使用razor模板创建一个视图，但我不想为模型编写一个类，因为在许多视图中我将有许多查询将返回不同的模型。

For example I have a linq query:

例如，我有一个linq查询：

from p in db.Articles.Where(p => p.user_id == 2)
select new
{
    p.article_id, 
    p.title, 
    p.date, 
    p.category,
    /* Additional parameters which arent in Article model */
};

I need to write a View for this query. This query returns a Articles.

我需要为此查询编写一个View。此查询返回文章。

Now I dont know how should looks like a model definition.

现在我不知道应该如何看起来像模型定义。

I tried to use this deffinition:

我试着用这个定义：

@model System.Collections.IEnumerable

But then I had an erros than fileds doesnt exists in object type:

但后来我有一个错误，而不是文件在对象类型中不存在：

*CS1061: 'object' does not contain a definition for 'addition_field' and no extension method 'addition_field' accepting a first argument of type 'object' could be found*

* CS1061：'object'不包含'addition_field'的定义，并且没有扩展方法'addition_field'接受类型'object'的第一个参数可以找到*

This is my model for which I do not want to write a next model. Of course

这是我的模型，我不想写下一个模型。当然

The short answer is that using anonymous types is not supported, however, there is a workaround, you can use an ExpandoObject

简短的回答是不支持使用匿名类型，但是，有一种解决方法，您可以使用ExpandoObject

Set your model to @model IEnumerable<dynamic>

将模型设置为@model IEnumerable

Then in the controller

然后在控制器中

from p in db.Articles.Where(p => p.user_id == 2)
select new
{
    p.article_id, 
    p.title, 
    p.date, 
    p.category,
    /* Additional parameters which arent in Article model */
}.ToExpando();

...
public static class Extensions
{
    public static ExpandoObject ToExpando(this object anonymousObject)
    {
        IDictionary<string, object> anonymousDictionary = HtmlHelper.AnonymousObjectToHtmlAttributes(anonymousObject);
        IDictionary<string, object> expando = new ExpandoObject();
        foreach (var item in anonymousDictionary)
            expando.Add(item);
        return (ExpandoObject)expando;
    }
}

I think this is an even better solution:

我认为这是一个更好的解决方案：

http://buildstarted.com/2010/11/09/razor-without-mvc-part-iii-support-for-nested-anonymous-types/

This allows for nested anonymous types, which the aforementioned expando-object solution won't handle.

这允许嵌套的匿名类型，前面提到的扩展对象解决方案将无法处理。

It seems you can't pass anonymous types but if you just want the values of the type you might pass an enumerable of an object array to view.

看起来你不能传递匿名类型，但是如果你只想要类型的值，你可以传递一个可枚举的对象数组来查看。

View:

视图：

@model IEnumerable<object[]>   

@{
    ViewBag.Title = "Home Page";
}

<div>   
    <table>
        @foreach (var item in Model)
        {
            <tr>
                <td>@item[0].ToString()</td>
                <td>@item[1].ToString()</td>
            </tr>
        }
    </table>
</div>

Controller:

控制器：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;

    namespace ZZZZZ
    {
        public class HomeController : Controller
        {
            public ActionResult Index()
            {

                List<object[]> list = new List<object[]> { new object[] { "test1", DateTime.Now, -12.3 } };

                return View(list);
            }


        }

    }
