孩子实在改不动了寻求大佬帮助

[Thechocolatemelt]

这段代码是我从网上借用别人进行测试的，但不知道为什么一运行就会报出无法转化类型的错误，litjson的版本也都改过了

 

using UnityEngine;
using LitJson;
using System.IO;
using System.Collections;
using System.Collections.Generic;
using System.Threading;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class TiggerTest : MonoBehaviour
{
    public void Start()
    {
        //json读取，读取Assets/Json/test.json文件
        string str = File.ReadAllText(Application.dataPath + "/Json/test.json");
        JsonData nameArray = JsonMapper.ToObject(str);
        foreach (JsonData jd in nameArray)
        {
            Debug.Log(jd["name"]);
        }

        //json写入，写入Assets/Json/item.json文件
        Item item1 = new Item(10, "sword");
        Item item2 = new Item(1, "cap");
        List<Item> items = new List<Item> { item1, item2 };
        File.WriteAllText(Application.dataPath + "/Json/item.json", JsonMapper.ToJson(items));
    }
}
[System.Serializable]   //Item类需要可序列化
public class Item
{
    public int id;
    public string name;
    public Item(int id, string name)
    {
        this.id = id;
        this.name = name;
    }
}
