C#⽗⼦ID的表数据转换成Tree型Json数据C#⽗⼦ID的表数据转换成Tree型Json数据在开发中有许多需要⽣成树型JSON数据的情况，⽐如侧边栏菜单、组织结构等，下⾯为两种JSON格式的数据⽣成⽅法。1.现在有这样字段的⽗⼦结构的表public class Node{ ///

/// id ///

public int id { get; set; } ///

/// 上级id ///

public int pid { get; set; } public string text { get; set; }}2.⽣成第⼀种格式的树型JSON字符串：JSON数据[ { "id":1, "pid":0, "text":"节点1", "children":[ { "id":2, "pid":1, "text":"节点1->2", "children":[ { "id":4, "pid":2, "text":"节点1->2->4", "children":[] }, { "id":5, "pid":2, "text":"节点1->2->5", "children":[] } ] }, { "id":3, "pid":1, "text":"节点1->3", "children":[ ] } ] }, { "id":6, "pid":0, "text":"节点6", "children":[ { "id":7, "pid":6, "text":"节点6->7", "children":[ { "id":8, "pid":7, "text":"节点6->7->8", "children":[] } ] } ] }]⽅案⼀：使⽤泛型，通过反射⽣成IEnumerable
