问题描述
请我需要一个LINQ表达你的帮助:
我已经嵌套表的对象,这是主要的对象层次的样子(每一划线是一个属性附加伤害子类的):
文件夹
-name
-List<&子文件夹GT;子文件夹
-name
-List<文件>文件
-name
-key
有对象的这种层次结构,我有文档的名字,我想寻找它返回它的父文件夹(子文件夹)
例如:
文件夹
-name:客户
-List<&子文件夹GT;子文件夹
-name:个人
-List<文件>文件
-name:恢复
- 键:1
如果我说: 恢复时,LINQ表达式应该返回我:子文件夹个人(对象)
请帮助我,因为两个嵌套列表中我有烦恼,有一个它会很容易。
先谢谢了。
文件夹
.SelectMany(S = GT; s.SubFolders)
.FirstOrDefault(S = GT; s.Documents.Any(D = GT; d.Name ==恢复));
我从这里臀部拍摄,但我认为的应的工作....
please I need your help with a Linq expression:
I have nested objects with lists, this is how the main object hierarchy looks like (each dash is an atribute of the sub-class):
Folder
-name
-List<Subfolder> Subfolders
-name
-List<Document> Documents
-name
-key
Having this hierarchy of objects, I have a Document name, and I want to search for it and return its parent folder (Subfolder)
Example:
Folder
-name: Customer
-List<Subfolder> Subfolders
-name: Personal
-List<Document> Documents
-name: Resume
-key : 1
If I said: "Resume", the linq expression should return me: the subfolder "Personal" (the object).
Please help me, because of the two nested lists I'm having troubles, with one it'll be easy.
Thanks in advance.
folders
.SelectMany(s => s.SubFolders)
.FirstOrDefault(s => s.Documents.Any(d => d.Name == "Resume"));
I'm shooting from the hip here but I think that should work....
