Hello,

Below is the class in my models

C#

public class LuceneSearchConfig
{
  public SearchResultObject getResults;

      public class SearchResultObject 
        {
            public Queue<List<string>> data { get; set; }
        }
}

---------------------------------
Below is my controller:

C#

test actionresult run()
{
  DCS.getResults = new LuceneSearchConfig.SearchResultObject();

DCS.getResults = DCS.SearchIndexWithTermQuery(xsearchtext, xtmmodel, 5);

 return PartialView("DocSearchResults", DCS.getResults);
}

---------------------------------
Below is my VIEW: (it won't open due to the wrong data type). Please see the error message below.)

HTML

@model IEnumerable<nowmvc.models.lucenesearchconfig.searchresultobject>

@foreach (var item in Model)
 {
// reading @item.data
}

Please help me how to send the correct type to the VIEW screen. Thank you.

What I have tried:

I tried to convert it to array but that won't work. I also tried casting "DCS.getResults" as IEnumerable and received errors below:

Quote:
The model item passed into the dictionary is of type 'System.Collections.Generic.Queue`1+Enumerator[System.Collections.Generic.List`1[System.String]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1

Here is a working mock of what you are trying to do:

1. Model

C#

using System.Collections.Generic;

namespace MvcQueue.Models
{
    public class DataModel
    {
        public Queue<List<string>> Data { get; set; } 
            = new Queue<List<string>>();
    }
}

2. Controller:

C#

using MvcQueue.Models;
using System.Collections.Generic;
using System.Web.Mvc;

namespace MvcQueue.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            var results = new DataModel();
            for (int i = 0; i < 10; i++)
            {
                results.Data.Enqueue(new List<string>() { "aaa", "bbb", "ccc" });
            }
            return View(results.Data);
        }
    }
}

3. View:

Razor

@{
    ViewBag.Title = "Queue Data Test";
}
<div>
    @foreach (var item in Model)
    {
        <p> data: 
        @string.Join(", ", item);
        </p>
    }
</div>

If you need to declare the Model in the view:

HTML

@Model = IEnumerable<List<string>>;
