Get Artists and show Artist Name as string

Question

Hi
I'm using VS2013, EF6, WPF
I have tables Media, MediaArtists, Artists
MediaArtist is a bridge table that use MediaId and ArtistId. it's mean that every Media has more Artists.
dbContext db = new dbContext();
mediumDataGrid.ItemsSource = db.Media.Select(m => new{
m.MediaId,
m.Title,
m.LastPlayedDate,
????m.MediaArtists.Select(a => Artist)????
}).ToList();
I want to get the Artists "Name" and show in gridview as Artist1, Artist2, Artist3
can you please let me know how do that?
thanks

Hello Zorig,
It seems that you are trying to perform a group by comma list in linq, if you data is not larger, you could use the LINQ2Object as below:
var result = db.X.ToList().Select(x => new { XID = x.XID, XName = x.XName, YNames = string.Join(",", x.Y.Select(y => y.XName)) }).ToList();
If data is large, you could check the workaround from Emran Hussain:

Or to use store produce for a complex query instead.
