没有，这是不可能的。试想一下：所有的LINQ to Entities查询翻译成SQL。其中的SQL语句包括自引用层次无限的深度？在标准的SQL，没有一个。如果有这种在T-SQL的延伸，我不知道它是什么，我不认为EF供应商做，无论是。

No, it isn't possible. Consider: All LINQ to Entities queries are translated into SQL. Which SQL statement includes an unlimited depth in a self-referencing hierarchy? In standard SQL, there isn't one. If there's an extension for this in T-SQL, I don't know what it is, and I don't think EF providers do, either.
