Question

Can you help me change this select command to linq to sql select command?

string value = ddl.SelectedValue;

SELECT  * 
FROM    Song 
WHERE   SongID IN (
            SELECT SongID 
            FROM   AlbumSong 
            WHERE  AlbumID = @value)

Here’s the linq approach with the more concise dot notation

var dataContext = new YouDataContext();
int value = 10;
dataContext.Song.Where(a => 
     dataContext.AlbumSong.Where(alSong => alSong.AlbumId == value)
                          .Select(alSong => alSong.SongId).Contains(a.SongId));
