推荐答案

不幸的是，我的附件图片在一个被阻止的URL上，所以我无法查看。您正在寻找的是递归查询，Google和其他地方有很多关于在原始SQL或EF中使用的代码的示例

Unfortunately your attached images are on a blocked URL by me, so I could not view. What you are looking for is a Recursive Query, there are plenty of examples on Google and elsewhere on the code to use in either raw SQL or EF
