LINQ to Entities多个连接

嗨我试图复制这个mysql查询

SELECT a.id, a.title, a.description, a.categories_id, c.name, d.title FROM ads AS a INNER JOIN locations AS b ON a.locations_id = b.id INNER JOIN areas AS c ON b.areas_id = c.id INNER JOIN categories AS d ON a.categories_id = d.id WHERE a.title LIKE '%mini%' AND c.name = 'Fyn' LIMIT 10 

这是在LINQ

 var query = (from a in db.ads join b in db.locations on a.locations_id equals b.id join c in db.areas on b.id equals c.id join d in db.categories on a.categories_id equals d.id where a.title.Contains(searchQuery) && c.name.Equals(area) select new { a.id, a.title, a.description, category = d.title }).Take(10); 

它没有显示任何错误，但它没有返回任何数据。

你在第三行有错误：

 join c in db.areas on b.id equals c.id 

应该

 join c in db.areas on b.areas_id equals c.id
