如何將此SQL內部連接查詢轉換爲LINQ語法？

Question

我不熟悉LINQ。我需要將這個查詢轉換成一個LINQ語句，供我的C＃項目使用。

感謝

SELECT Galleries.GalleryTitle, Media.* 
FROM Galleries 
INNER JOIN Media ON Galleries.GalleryID = Media.GalleryID 
WHERE (Galleries.GalleryID = 100) 

Answer 1

var query = 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 }; 

物業Media將包含加入媒體實體的名單。另外，如果您在Gallery實體中定義了導航屬性，那麼：

var gallery = db.Galleries.Include("Media") 
       .FirstOrDefault(g => g.GalleryID == 100);
