C#在listBox中列出的项在循环中序列化为json

Question

所以我在这方面是个新手，我有个问题。

我想要加载一个XML文件并从中获取一个属性，这是可行的。现在我想把它序列化成一个JSON格式的文件，但是现在我被困住了，而且我的头变得疯狂了，…

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Xml;
using Newtonsoft.Json;
using Formatting = Newtonsoft.Json.Formatting;

namespace WindowsFormsApp2
{
    public partial class Form1 : Form
    {     
        public Form1()
        {
            InitializeComponent();
            Loadtype();
            //Load XML
            XmlDocument doc = new XmlDocument();
            doc.Load("types.xml");

            foreach (XmlNode node in doc.DocumentElement)
            {
                string value = listBox.Text.ToString();
                string name = node.Attributes[0].Value;
                listBox.Items.Add(new type(name));
            }
            
        }      

        private void button1_Click(object sender, EventArgs e)
        {

         
            Item test = new Item()
            {               
              
                m_Version = 9,
                DisplayName = "Trader",
                Icon = "Trader",
                Color = "ef5252FF",
                InitStockPercent = 100,
                
                Items = new List<Root>()
                {

                    new Root { ClassName = "", MaxPriceThreshold = 5000, MinPriceThreshold = 5000, SellPricePercent = -1, MaxStockThreshold = 1, MinStockThreshold = 1, QuantityPercent = -1 },
   
                }

            };
                string json = JsonConvert.SerializeObject(test, Formatting.Indented);
                Console.WriteLine(json);
                Console.Read();
            



            foreach (var line in listBox.Items)
            { 
                
            }

            const string sPath = "save.json";
            System.IO.StreamWriter SaveFile = new System.IO.StreamWriter(sPath);
            SaveFile.Close();
            MessageBox.Show("Expansion Trader Market .json saved!");
        }

        public class Item
        {

            public int m_Version { get; set; }
            public string DisplayName { get; set; }
            public string Icon { get; set; }
            public string Color { get; set; }
            public int InitStockPercent { get; set; }
            public List<Root> Items { get; set; } 

        }

        public class Root
        {
            public string ClassName { get; set; }
            public int MaxPriceThreshold { get; set; }
            public int MinPriceThreshold { get; set; }
            public int SellPricePercent { get; set; }
            public int MaxStockThreshold { get; set; }
            public int MinStockThreshold { get; set; }
            public int QuantityPercent { get; set; }
        }

        private void Loadtype()
        {


        }

        private void listBox_SelectedIndexChanged(object sender, EventArgs e)
        {

        }
    }
}

输出(除了一件事外，这很好)

{
  "m_Version": 9,
  "DisplayName": "Trader",
  "Icon": "Trader",
  "Color": "ef5252FF",
  "InitStockPercent": 100,
  "Items": [
    {
      "ClassName": "",
      "MaxPriceThreshold": 5000,
      "MinPriceThreshold": 5000,
      "SellPricePercent": -1,
      "MaxStockThreshold": 1,
      "MinStockThreshold": 1,
      "QuantityPercent": -1
    }
  ]
}

我想要达到的是，我的列表框中列出的所有项目都应该有：

   {
  "m_Version": 9,
  "DisplayName": "Trader",
  "Icon": "Trader",
  "Color": "ef5252FF",
  "InitStockPercent": 100,
  "Items": [
    {
        "ClassName": "<listeditem of listbox>",
        "MaxPriceThreshold": 5000,
        "MinPriceThreshold": 5000,
        "SellPricePercent": -1,
        "MaxStockThreshold": 1,
        "MinStockThreshold": 1,
        "QuantityPercent": -1
    },
    {
        "ClassName": "<listeditem of listbox>",
        "MaxPriceThreshold": 5000,
        "MinPriceThreshold": 5000,
        "SellPricePercent": -1,
        "MaxStockThreshold": 1,
        "MinStockThreshold": 1,
        "QuantityPercent": -1
    }
  ]
}

XML文件：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

    <type name="MMG_JPC_Vest_alpine">
        <nominal>1</nominal>

试试这段代码

    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.LoadXml(xml);
    XmlNode node = xmlDoc.SelectSingleNode("types");

    var rawjson = JsonConvert.SerializeXmlNode(node); 
    var json = JObject.Parse(rawjson).ToString().Replace("@","");

    var path = @"C:\";
    File.WriteAllText(Path.Combine(path, "save.json"), json);
