unity将多层嵌套的结构体与json字符串相互转化

定义多个结构体，将结构体内容输入到最终的JObject中，然后将其转为字符串打印出来，即可。
代码内容如下：

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using UnityEngine;

public class Test : MonoBehaviour
{
	private Apple apple;
	private Banana banana;
    private void Start()
    {
		apple = new Apple();
		apple.color = "red";
		apple.size = 10;
		apple.breed = "红富士";

		Monkey monkey = new Monkey();
		monkey.breed = "金丝猴";
		monkey.habitat = "高山密林";

		banana = new Banana();
		banana.breed = "芭蕉";
		banana.monkey = (JObject)JsonConvert.DeserializeObject(JsonConvert.SerializeObject(monkey));

		JObject fruitJObject = new JObject();
		fruitJObject["Apple"] = (JObject)JsonConvert.DeserializeObject(JsonConvert.SerializeObject(apple));
		fruitJObject["Banana"] = (JObject)JsonConvert.DeserializeObject(JsonConvert.SerializeObject(banana));

		Debug.Log(fruitJObject.ToString());
	}
}

/// <summary>
/// 苹果结构体
/// </summary>
struct Apple
{
	public string color;
	public int size;
	public string breed;
}


/// <summary>
/// 香蕉结构体
/// </summary>
struct Banana
{
	public string breed;//!<品种
	public JObject monkey;//!<猴子
}

/// <summary>
/// 猴子结构体
/// </summary>
struct Monkey
{
	public string breed;//!<品种
	public string habitat;//!<栖息地
}

运行结果如下：

将接收到的json字符串转为JObject类型，然后取出对应的值并打印出来，代码如下：

		string jsonStr = fruitJObject.ToString();
		JObject jsonJObject = (JObject)JsonConvert.DeserializeObject(jsonStr);
		Apple appleObject = JsonConvert.DeserializeObject<Apple>(JsonConvert.SerializeObject(jsonJObject["Apple"]));
		Debug.Log(appleObject.breed);

运行结果如下：
