如何將該SQL轉換為LINQ語法？

Question

架構就像

具有所需結果的SQL查詢如下

SELECT   dbo.Products.*
FROM     dbo.ProductManufacturers INNER JOIN
         dbo.Products ON dbo.ProductManufacturers.ProductID = dbo.Products.ProductID INNER JOIN
         dbo.Manufacturers ON dbo.ProductManufacturers.ManufacturerID = dbo.Manufacturers.ManufacturerID
WHERE    (dbo.ProductManufacturers.ManufacturerID = 1)

LINQ如何獲得相同的結果？

Answer 1

如果所有外鍵均已設置，則應執行以下操作：

db.Manufacturers.Where(t => t.ManufacturerID == id)
                .SelectMany(s => s.Products)
                .ToList();
