razor view with anonymous type model class. It is possible?

Solution 1:

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

Set your model to @model IEnumerable<dynamic>

Then in the controller

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;
    }
}

Solution 2:

The simplest solution if you are using C# 7.0+ (introduced in Visual Studio 2017+) is to use a tuple rather than an anonymous type.

Razor View: "_MyTupledView.cshtml"

@model (int Id, string Message)

<p>Id: @Model.Id</p>
<p>Id: @Model.Message</p>

Then when you bind this view, you just send a tuple:

var id = 123;
var message = "Tuples are great!";
return View("_MyTupledView", (id, message))

Solution 3:

I think this is an even better solution:

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.

Solution 4:

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.

View:

@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:

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);
            }


        }

    }
