Question

i have this LINQ query on two tables

public ViewResult data()
        {
            var query = from a in DB.Album
                        join b in DB.Artists
                        on a.ArtistId equals b.ArtistId
                        where (b.ArtistId == 2)
                       select new { a ,b };

            return View(query.ToList());
        }

however i am confused how do i display these data i.e Artist table’s Artist name and Album tables Album Name in my view?

i am trying something like this but it gives me a error

@model IEnumerable<test1.Models.Album>


@{
    ViewBag.Title = "data";
}

<h2>data</h2>

@Model.Count()
<br />
<ul>
@foreach (var mod1 in Model)
{
    <li>

   @* @mod1.Genre.Name*@
      @Html.DisplayFor(modelItem => mod1.Artist.Name)
    <br />
    @mod1.AlbumId
   <br />
    @mod1.Artist
    <br />
    @mod1.Title
    </li>
}
</ul>

Error i get is

The model item passed into the dictionary is of type ‘System.Collections.Generic.List1[<>f__AnonymousType1
2[test1.Models.Album,test1.Models.Artist]]’,
but this dictionary requires a model item of type ‘System.Collections.Generic.IEnumerable`1[test1.Models.Album]’.

Any idea ?

Answer 1

You are getting the exception because you are trying to pass a list of anonymous objects
instead of a list of albums.

You can create a viewmodel so you can use that type as your model.

public class ArtistAlbumViewModel
{
    Artist Artist { get; set; }
    Album Album { get; set; }
}

Use this type when you return values from the query.

var query = from a in DB.Album
            join b in DB.Artists
            on a.ArtistId equals b.ArtistId
            where (b.ArtistId == 2)
            select new ArtistAlbumViewModel { Album = a, Artist = b };

Then you should strongly type your view to this type and edit the view according to your viewmodel.

@model IEnumerable<test1.Models.ArtistAlbumViewModel>
