不能在轉換後的查詢（普通SQL到LINQ）

Question

我想這個工作的SQL查詢轉換爲LINQ查詢（EF）

訪問表，但在LINQ查詢我不能進入該類別數據表。 這是我工作的SQL查詢：

SELECT cosmetics.brand, cosmetics.product, cosmetics.size, cosmetics.price, cosmetics.sale_type, cosmetics.description, cosmetics.date, cosmetics.company_id, cosmetics.category, cosmetics.[male-female], company.company_site 
FROM cosmetics INNER JOIN company ON cosmetics.company_id = company.company_id 
WHERE (cosmetics.date >= GETDATE()) 
    AND (cosmetics.[male-female] = N'female') 
    AND (cosmetics.category = N'cosmetics_perfumes') 
ORDER BY cosmetics.brand, cosmetics.product, cosmetics.size, cosmetics.price" 

這工作得很好：

var female = (from c in db.cosmetics 
       .Where(v => v.date > DateTime.Now) 
       .Where(d => d.male_female == "female") 
       .Include("company") 
      select c); 
return View(female.ToList()); 

Answer 1

var q = 
    from cos in oc.cosmetics 
    join com in oc.company on cos.company_id equals com.company_id 
    where cos.date >= DateTime.Now 
    && cos.male_female == "female" 
    && cos.category == "cosmetics_perfumes" 
    orderby cos.brand, cos.product, cos.size, cos.price 
    select new { cos, com.company_site };
