今天在網上看到一個simplejson，直接調用這兩個API就可以了，簡單易用

string jsonstr = SimpleJson.SimpleJson.SerializeObject(json);
Debug.LogError(jsonstr);
TestJson test = SimpleJson.SimpleJson.DeserializeObject<TestJson>(jsonstr);

做了測試和JsonUtility.ToJson(json);幾乎是一樣的，但是JsonUtility.ToJson(json); 需要在每個類上加上[System.Serializable] 特性標簽 ，並且只能用字段，不能用屬性 ，都可以滿足我們日常需求

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class TestJson
{
    [SerializeField] //經測試，加不加都可以
    public string Name;
    [SerializeField]
    public Student[] stud;
}
[System.Serializable]
public class Student
{
    [SerializeField]
    
 
public string School;
    [SerializeField]
    public Gender gender;
}

[System.Serializable]
public class Gender
{
    [SerializeField]
    public int age;
    [SerializeField]
    public List<int> list;
}



public class TestSimpliJson : MonoBehaviour
{

    // Use this for initialization
    void
 
 Start()
    {
        Tess();
    }
    void Tess()
    {
        TestJson json = new TestJson();
        json.Name = "飛天小豬";
        json.stud = new Student[4];

        for (int i = 0; i < json.stud.Length; i++)
        {
            json.stud[i] = new Student();
            json.stud[i].School = "飛天小豬" + i;
            json.stud[i].gender = new Gender();
            json.stud[i].gender.age = i;
            json.stud[i].gender.list = new List<int>();
            for (int j = 0; j < i * i; j++)
            {
                json.stud[i].gender.list.Add(j);
            }
        }

        string jsonstr = SimpleJson.SimpleJson.SerializeObject(json);
        Debug.LogError(jsonstr);
        TestJson test = SimpleJson.SimpleJson.DeserializeObject<TestJson>(jsonstr);
        string strJson = JsonUtility.ToJson(json);
        Debug.LogError(strJson);
    }
}

兩種方式，輸出如下

{"Name":"飛天小豬","stud":[{"School":"飛天小豬0","gender":{"age":0,"list":[]}},{"School":"飛天小豬1","gender":{"age":1,"list":[0]}},{"School":"飛天小豬2","gender":{"age":2,"list":[0,1,2,3]}},{"School":"飛天小豬3","gender":{"age":3,"list":[0,1,2,3,4,5,6,7,8]}}]}

不過如果不給list賦值，稍微有點不一樣的地方

{"Name":"飛天小豬","stud":[{"School":"飛天小豬0","gender":{"age":0,"list":null}},{"School":"飛天小豬1","gender":{"age":1,"list":null}},{"School":"飛天小豬2","gender":{"age":2,"list":null}},{"School":"飛天小豬3","gender":{"age":3,"list":null}}]}

{"Name":"飛天小豬","stud":[{"School":"飛天小豬0","gender":{"age":0,"list":[]}},{"School":"飛天小豬1","gender":{"age":1,"list":[]}},{"School":"飛天小豬2","gender":{"age":2,"list":[]}},{"School":"飛天小豬3","gender":{"age":3,"list":[]}}]}
