嘿,我这里有这段代码,与它斗争了好几个小时.这个sql语句的作用基本上是获取指定文件夹的所有子文件夹(@compositeId).

WITH auto_table (id, Name, ParentID) AS
(
SELECT
    C.ID, C.Name, C.ParentID
FROM Composite_Table AS C
    WHERE C.ID = @compositeId

UNION ALL

SELECT
    C.ID, C.Name, C.ParentID
FROM Composite_Table AS C
    INNER JOIN auto_table AS a_t ON C.ParentID = a_t.ID
)

SELECT * FROM auto_table

此查询将返回如下内容:

• Id | 名称| 的ParentId
• 1 | StartFolder | 空值
• 2 | Folder2 | 1
• 4 | Folder3 | 1
• 5 | Folder4 | 4

现在我想将代码转换为linq.我知道它涉及某种形式的递归,但仍然因为with语句而停滞不前.救命？
