如何将此SQL转换为实体框架LINQ查询

有人能帮我把这个SQL查询转换成EntityFramework LINQ吗

DECLARE @UserId varchar(50) = '123'
SELECT
   TL.TrackId, 
   COUNT(*) AS LikeCount,
   (SELECT IIF(COUNT(*) > 0, 'true','false') FROM UserTrackLikes WHERE
    UserId = @UserId AND TrackId = TL.TrackId) AS IsLiked
FROM TrackList AS TL
LEFT OUTER JOIN UserTrackLikes AS UTL 
ON UTL.TrackId = TL.TrackId
GROUP BY TL.TrackId

---

您可以使用查询语法：

int userId = 123;
var result = (from trackList in context.TrackLists
              select new 
              {
                 trackList.TrackId,
                 LikeCount = trackList.Likes.Count(),
                 IsLiked = trackList.Likes.Any(x => x.UserId == userId)
              }).ToList();

假设这里，

Likes

是

UserTrackLike

的集合，声明如下：

public ICollection<UserTrackLike> Likes { get; set; }

公共ICollection类似于{get；set；}

您仍然可以使用

DbSet.SqlQuery

方法在entity framework 6中使用sql。@JEUX20是的，但我想知道如何将其转换为linq。
