在C#中将层次字符串列表转换为JSON

Question

我有一个表示分层数据的字符串列表，它们是用连字符分隔的(3个连字符表示分隔)。我正在尝试将此列表转换为JSON字符串，以便可以将其绑定到树控件。

我正在寻找一个C#的例子。

列表可以如下所示(列表并不是完整的列表，在某些情况下它可以有7个节点，但你可以理解它的意思)：

Automotive Electronics
Automotive Electronics---Body Electronics
Automotive Electronics---Body Electronics---Access Control Systems
Automotive Electronics---Body Electronics---Body Control Modules
Automotive Electronics---Driver Information
Automotive Electronics---Driver Information---Clocks
Automotive Electronics---Driver Information---Compass Systems
Automotive Electronics---HomeL
Automotive Electronics---Infotainment & Connectivity
Automotive Electronics---Infotainment & Connectivity---Handsfree Systems
Automotive Interiors
Automotive Interiors---Door Panels
Automotive Interiors---Floor Consoles
Automotive Interiors---Headliners & Overhead Systems
Automotive Interiors---Overhead Consoles
Automotive Seating
Automotive Seating---Complete Seats
Automotive Seating---Complete Seats---SuperThin Seats

Answer 1

主要的技巧是将字符串放入树结构中。接下来的代码片段(linqpad)可以做到这一点。我不知道输出是不是可以在客户端处理，但它应该是您可以根据自己的需要进行修改的东西。

void Main()
{
    var rootNode = new Node("root");
    foreach(string s in new[] {"Automotive Electronics",
        "Automotive Electronics---Body Electronics",
        "Automotive Electronics---Body Electronics---Access Control Systems",
        "Automotive Electronics---Body Electronics---Body Control Modules",
        "Automotive Electronics---Driver Information",
        "Automotive Electronics---Driver Information---Clocks",
        "Automotive Electronics---Driver Information---Compass Systems",
        "Automotive Electronics---HomeL",
        "Automotive Electronics---Infotainment & Connectivity",
        "Automotive Electronics---Infotainment & Connectivity---Handsfree Systems",
        "Automotive Interiors",
        "Automotive Interiors---Door Panels",
        "Automotive Interiors---Floor Consoles",
        "Automotive Interiors---Headliners & Overhead Systems",
        "Automotive Interiors---Overhead Consoles",
        "Automotive Seating",
        "Automotive Seating---Complete Seats",
        "Automotive Seating---Complete Seats---SuperThin Seats"})
    {
        AddNodes(rootNode, s.Split(new[] {"---"}, StringSplitOptions.RemoveEmptyEntries));
    }
    new JavaScriptSerializer().Serialize(rootNode.Nodes).Dump();
}

public void AddNodes( Node parentNode, string[] names)
{
    if (names.Any())
    {
        var node = parentNode.AddNode(names.First());
        AddNodes(node, names.Skip(1).ToArray());
    }
}

public class Node
{
    public Node(string name)
    {
        Name = name;
        Nodes = new List<Node>();
    }

    public Node AddNode(string name)
    {
        if (!this.Nodes.Select(n => n.Name).Contains(name.Trim()))
        {
            //name.Dump(this.Name);
            this.Nodes.Add(new Node(name.Trim()));
        }
        return this.Nodes.Where (n => n.Name == name).First();
    }

    public string Name { get;set;}
    public List<Node> Nodes { get; set; }
}

输出：

[{“名称”：“汽车电子”，“节点”：[{“名称”：“车身电子”，“节点”：[{“名称”：“门禁系统”，“节点”：[]}，{“名称”：“车身控制模块”，“节点”：[]}]}，{“名称”：“驾驶员信息”，“节点”：[{“名称”：“时钟”，“节点”：[]}，{“名称”：“指南针系统”，"Nodes":[]}]}，{"Name":"HomeL"，"Nodes":[]}，{“Name”：“信息娱乐与连接”，“Nodes”：[{“Name”：“免提系统”，"Nodes":[]}，{“Name”：“汽车内饰”，“Nodes”：[{“Name”：“门板”，"Nodes":[]}，{“Name”：“地板控制台”，“Nodes”：[]}，{“名称”：“车顶和架空系统”，“节点”：[]}，{“名称”：“架空控制台”，“节点”：[]}}，{“名称”：“汽车座椅”，“节点”：[{“名称”：“完整座椅”，“节点”：[{“名称”：“SuperThin座椅”，“节点”：[]}}]

(请注意，对于JavaScriptSerializer，您必须在linqpad中导入一些名称空间才能运行此代码片段)。
