今天在网上看到一个simplejson，直接调用这两个API就可以了，简单易用

string jsonstr = SimpleJson.SimpleJson.SerializeObject(json);

Debug.LogError(jsonstr);

TestJson test = SimpleJson.SimpleJson.DeserializeObject<TestJson>(jsonstr);

做了测试和JsonUtility.ToJson(json);几乎是一样的，但是JsonUtility.ToJson(json); 需要在每个类上加上[System.Serializable] 特性标签 ，并且只能用字段，不能用属性 ，都可以满足我们日常需求

using System.Collections;using System.Collections.Generic;using UnityEngine;[System.Serializable]public class TestJson{    [SerializeField] //经测试，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
     
       list;}public class TestSimpliJson : MonoBehaviour{    // Use this for initialization    void Start()    {        Tess();    }    void Tess()    {        TestJson json = new TestJson();        json.Name = "飞天小猪";        json.stud = new Student[4];        for (int i = 0; i < json.stud.Length; i++)        {            json.stud[i] = new Student();            json.stud[i].School = "飞天小猪" + i;            json.stud[i].gender = new Gender();            json.stud[i].gender.age = i;            json.stud[i].gender.list = new List
      
       ();            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
       
        (jsonstr);        string strJson = JsonUtility.ToJson(json);        Debug.LogError(strJson);    }}
       
      
     

 

两种方式，输出如下

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

 

 不过如果不给list赋值，稍微有点不一样的地方

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

 

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