Json字符串格式问题 [英] Json string format question

问题描述

嗨 

这是我的json字符串

this is my json string

[{"Nid":1,"Name":"user1","Info":{"Age":10,"Address":"xxxxxxx","Note":"rrrrrr"}},{"Nid":2,"Name":"user2","Info":{"Age":20,"Address":"sssssss","Note":"ccccccc"}},{"Nid":3,"Name":"user3","Info":{"Age":30,"Address":"rrrrrrr","Note":"vvvvvvv"}},{"Nid":4,"Name":"user4","Info":{"Age":40,"Address":"aaaaa","Note":"bbbbb"}}]

这是我的代码，使用EntityFrameworkCore

and this is my code, use EntityFrameworkCore

 return Json(await _context.UserInfo.Select(u => new { Nid = u.Nid, Name = u.Name,Info=new { Age=u.Age,Address=u.Address,Note=u.Note } }).ToListAsync());

现在我想生成像这样的json字符串

now I want generate json string like this

< span style ="font-family：monospace;字体大小：11.9925px; white-space：pre-wrap"> [{" Nid"：1，"Name"："user1"，"Info"： [ {" Age"：10，" ;地址"：" xxxxxxx"，" Note"：" rrrrrr"} ] }，{" Nid"：2，" Name"：" user2"，" Info" ;： [ {" Age"：20，" Address"：" sssssss"，" Note"：" ccccccc"} ] }，{" ; Nid的"：3，"姓名"："用户3"，"详情"：的 [ {"年龄"：30，"地址]按钮：" RRRRRRR"，"注意" ;：" vvvvvvv"} ] }，{" Nid"：4，" Name"：" user4"，" Info"： [ {" ;年龄"：40，"地址"："aaaaa"，"注意"："bbbbb"} ] }]

[{"Nid":1,"Name":"user1","Info": [ {"Age":10,"Address":"xxxxxxx","Note":"rrrrrr"} ] },{"Nid":2,"Name":"user2","Info": [ {"Age":20,"Address":"sssssss","Note":"ccccccc"} ] },{"Nid":3,"Name":"user3","Info":[{"Age":30,"Address":"rrrrrrr","Note":"vvvvvvv"} ] },{"Nid":4,"Name":"user4","Info":[{"Age":40,"Address":"aaaaa","Note":"bbbbb"} ] }]

How do i do change my code ? (add [] at "info" column) thanks !!

推荐答案

是的，info需要是一个数组，所以请将数据包装起来。

Yes, info needs to be an array so wrap the data as such.

Info = new [] {
   new { Age = u.Age, Address = u.Address, ... }
}
