unity生成和解析Json

using LitJson;   //注意引用命名空间
using UnityEngine;

public class LitJsonDemo : MonoBehaviour {

    // Use this for initialization
    void Start()
    {
        //============JSON的生成============================
        JsonData data = new JsonData();
        data["name"] = "Czhenya";
        //生成嵌套结构的json
        data["info"] = new JsonData();
        data["info"]["age"] = 28;
        data["info"]["sex"] = "男";

        string js1= data.ToJson();
        Debug.Log(js1);

        //============使用jsonMapper生成Json==================
        //此方法使用的前提是有一个玩家类
        Player play1 = new Player();
        play1.name = "czy";
        play1.age = 22;
        play1.sex = "男";

        string js2 = JsonMapper.ToJson(play1);
        Debug.Log(js2);

        //============使用JsonWritter生成Json==================
        JsonWriter js3 = new JsonWriter();
        //对象类型的json
        js3.WriteObjectStart();
        js3.WritePropertyName("name");
        js3.Write("zhenya");
        js3.WritePropertyName("age");
        js3.Write("30");
        js3.WritePropertyName("sex");
        js3.Write("女");
        js3.WriteObjectEnd();
        Debug.Log(js3.ToString());

        JsonWriter js4 = new JsonWriter();
        //生成数组型json
        js4.WriteArrayStart();
        js4.Write("CZHENYA");
        js4.Write("25");
        js4.Write("男");
        js4.WriteArrayEnd();
        Debug.Log(js4.ToString());

        //需要注意的是有开始就要写结束

        JsonWriter js5 = new JsonWriter();
        //生成数组含对象
        js5.WriteArrayStart();
        //第一个对象
        js5.WriteObjectStart();
        js5.WritePropertyName("name");
        js5.Write("zhenya");
        js5.WritePropertyName("age");
        js5.Write("30");
        js5.WritePropertyName("sex");
        js5.Write("女");
        js5.WriteObjectEnd();
        //第二个对象
        js5.WriteObjectStart();
        js5.WritePropertyName("name");
        js5.Write("CZHENYA");
        js5.WritePropertyName("AGE");
        js5.Write("30");
        js5.WritePropertyName("SEX");
        js5.Write("男");
        js5.WriteObjectEnd();

        js5.WriteArrayEnd();

        Debug.Log(js5.ToString());

        //==========解析JSON 上面创建的Json1================
        JsonData jsdata1 = JsonMapper.ToObject(js1);
        Debug.Log("解析json1    "+jsdata1["name"]+" "+jsdata1["info"]["age"]+"");

        //遍历JsonData的key由于JsonData实现了IDictionary接口，所以可以使用Foreach进行遍历
        IDictionary dic = jsdata1 as IDictionary;
        foreach (string item in dic.Keys)
        {
            Debug.Log(item);
        }


        //===========解析上面的js2====================
        Player play2 = JsonMapper.ToObject<Player>(js2);
        Debug.Log("解析js2    " + play2.name + " " + play2.age);


        //===========解析上面的js3，js4，js5 转换成字符串 js3为例====================
        string json3 = js3.ToString();   
        JsonData jsdata3 = JsonMapper.ToObject(json3);   
        Debug.Log("解析js3    "+jsdata3["name"]+jsdata3["age"]+jsdata3["sex"]);
    }
    //玩家类
    public class Player
    {
         public string name { get; set; }
         public int age { get; set; }
         public string sex { get; set; }
    }
}
