How to handle IEnumerable with IGrouping in the view? - linq

Question

I am trying to send to the view an IEnumerable and to show every element in it but I have a problem when I send it. It says that:
{System.Linq.Enumerable.WhereSelectEnumerableIterator<System.Linq.IGrouping<string,MvcApplication4.Models.USER>,<>f__AnonymousType8<string,int>>}
and I dont know how to handle it.
This is my view :
#model IEnumerable<dynamic>
I get dynamic because i go to this view from couple of functions how send different types.
<table border="1" style="text-align:center">
<tr>
<td> </td>
<td> user name </td>
<td>age </td>
<td>comments </td>
</tr>
#foreach (var t in (Model))
{
<tr>
<td>#(count++))</td>
<td> #Console.WriteLine(t)</td>
<td> </td>
<td> </td>
</tr>
}
</table>
I get the IEnumerable from this linq :
var allU = (from m in comList
join c in users on m.user equals c.user into cm1
from cm2 in cm1.DefaultIfEmpty()
group cm2 by m.user into grouped
select new { name = grouped.Key, count = grouped.Count() }).AsEnumerable();
So my question is really : how can I get the elements of it in the view?

Answer 1

You can't reference the type in your view because it is an anonymous type. Instead, define a type to store the results of your query:
public class Result
{
public string Name { get; set; }
public int Count { get; set; }
}
Then change your query to project into that type:
var allU = (from m in comList
join c in users on m.user equals c.user into cm1
from cm2 in cm1.DefaultIfEmpty()
group cm2 by m.user into grouped
select new Result { Name = grouped.Key, Count = grouped.Count() }).AsEnumerable();
Then you'll be able to bind to the type IEnumerable<Result> in your view.
