一、使用JsonUnity创建Json

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

[Serializable]
public class Person
{
    public string name;
    public int age;
}

public class JSON_Gary : MonoBehaviour {

    // Use this for initialization
    void Start () {
        //Json操作 两种方式 ListJson JsonUtility
        //使用代码的方式创建一个json
        //{'name':'Gary','age':20}

        Person p1 = new Person();
        p1.name = "Gary";
        p1.age = 20;
        //转成json字符串
        string jsonStr = JsonUtility.ToJson(p1);
        Debug.Log(jsonStr);

    }
    
}

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

[Serializable]
public class Person
{
    public string name;
    public int age;
}


[Serializable]
public class Persons
{
    public Person[] persons;
}

public class JSON_Gary : MonoBehaviour {

    // Use this for initialization
    void Start () {
        //Json操作 两种方式 ListJson JsonUtility
        //使用代码的方式创建一个json
        //{'name':'Gary','age':20}

        Person p1 = new Person();
        p1.name = "Gary";
        p1.age = 20;
        //转成json字符串
        string jsonStr = JsonUtility.ToJson(p1);
        //Debug.Log(jsonStr);

        //{'persons':[{'name':'Gary','age':20},{'name':'Gary2','age':25}]}
        Person p2 = new Person();
        p2.name = "Gary2";
        p2.age = 25;
        Person[] ps = new Person[] { p1, p2 };

        Persons persons = new Persons();
        persons.persons = ps;
        jsonStr = JsonUtility.ToJson(persons);
        Debug.Log(jsonStr);

    }
    
}

二、使用JsonUtility解析Json

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

[Serializable]
public class Person
{
    public string name;
    public int age;
}


[Serializable]
public class Persons
{
    public Person[] persons;
}

public class JSON_Gary : MonoBehaviour {

    // Use this for initialization
    void Start () {
        //Json操作 两种方式 ListJson JsonUtility
        //使用代码的方式创建一个json
        //{'name':'Gary','age':20}

        Person p1 = new Person();
        p1.name = "Gary";
        p1.age = 20;
        //转成json字符串
        string jsonStr = JsonUtility.ToJson(p1);
        //Debug.Log(jsonStr);

        //{'persons':[{'name':'Gary','age':20},{'name':'Gary2','age':25}]}
        Person p2 = new Person();
        p2.name = "Gary2";
        p2.age = 25;
        Person[] ps = new Person[] { p1, p2 };

        Persons persons = new Persons();
        persons.persons = ps;
        jsonStr = JsonUtility.ToJson(persons);
        //jsonStr ={ 'persons':[{'name':'Gary','age':20},{'name':'Gary2','age':25}]}
        //Debug.Log(jsonStr);

        //解析Json
        Persons newPersons = JsonUtility.FromJson<Persons>(jsonStr);
        Debug.Log(newPersons.persons[0].name);

    }
    
}
