一：介绍

JsonUtility是Unity自带的一个类，简单，效率高，不依赖第三方的库，但是对于一些复杂的要求还是需要导入第三方库去实现

二：使用

{"personList":[{"Name":"liu","Age":1},{"Name":"Yin","Age":2}]}

using System.Collections.Generic;using UnityEngine;using System;public class ParseJson : MonoBehaviour{    private void Awake()    {        TextAsset json_txt = Resources.Load
   
    ("TestJson");        PersonRoot data = JsonUtility.FromJson
    
     (json_txt.text);        foreach (var temp in data.personList)        {            Debug.Log(String.Format("姓名:{0}==年龄{1}", temp.Name, temp.Age));        }    }}[Serializable]public class PersonData{    public string Name;    public int Age;}[Serializable]public class PersonRoot{    public List
     
       personList;}
     
    
   

三：踩坑点

——JsonUtility.FromJson方法只能接受一个JSON对象，否则会报错“JSON must represent an object type”

——无法直接解析枚举类型

using System.Collections.Generic;using UnityEngine;using System;public class ParseJson : MonoBehaviour{    private void Awake()    {        TextAsset json_txt = Resources.Load
   
    ("TestJson");        PersonRoot data = JsonUtility.FromJson
    
     (json_txt.text);        foreach (var temp in data.personList)        {            Debug.Log(String.Format("姓名:{0}==年龄{1}==类型{2}", temp.Name, temp.Age, temp.PersonType));        }    }}[Serializable]public class PersonData : ISerializationCallbackReceiver{    public string Name;    public int Age;    public PersonType PersonType;    public string PersonTypeStr;    public void OnAfterDeserialize()    {        PersonType type = (PersonType)Enum.Parse(typeof(PersonType), PersonTypeStr);        PersonType = type;    }    public void OnBeforeSerialize()    {        throw new NotImplementedException();    }}[Serializable]public class PersonRoot{    public List
     
       personList;}public enum PersonType{    Teacher,    Student,}
