無法隱式轉換類型'System.Linq.IQueryable <AnonymousType＃1>'

Question

在我的C＃項目中遇到了一個錯誤，導致我頭痛。錯誤是：

Cannot implicitly convert type 'System.Linq.IQueryable<AnonymousType#1>' 
to System.Collections.Generic.IEnumerable<KST.ViewModels.Gallery>'. 

這裏是我的LINQ querys：

//Get Single Picture 
var PictureResults = (from m in DB.Media where m.MediaID == 450 select m).SingleOrDefault(); 

//Get Gallery Pictures and Gallery Title 
var GalleryResults = from g in DB.Galleries 
        join m in DB.Media on g.GalleryID equals m.GalleryID into gm 
        where g.GalleryID == 100 
        select new { g.GalleryTitle, Media = gm }; 

這裏是我的ViewModels。下GalleryResults發生

public class GalleryViewModel 
{ 
    public Media Media { get; set; } 
    public IEnumerable<Gallery> Gallery { get; set; } 
} 

public class Gallery 
{ 
    public string GalleryTitle { get; set; } 
    public int MediaID { get; set; } 
    public int GalleryID { get; set; } 
    public string MediaGenre { get; set; } 
    public string MediaTitle { get; set; } 
    public string MediaDesc { get; set; } 
} 

的squigally行錯誤：

//Create my viewmodel 
var Model = new GalleryViewModel 
{ 
    Media = PictureResults, 
    Gallery = GalleryResults 
};

您正在投射一系列匿名類型而不是Gallery。只需在您的select語句中實例化Gallery對象，它應該可以工作。

var GalleryResults = from g in DB.Galleries 
        join m in DB.Media on g.GalleryID equals m.GalleryID into gm 
        where g.GalleryID == 100 
        select new Gallery { GalleryTitle = g.GalleryTitle, Media = gm };
