Unity Json解析-保存Json文件

1.第一种unity自带解析的API  JsonUtility 读取Json 不需要dll文件

2.第二种 Newtonsoft.Json dll解析json  读取json  需要dll文件(下载地址) 免费的

json格式如下

{

  "name": [
    {
      "age": 28,
      "sex": "不男不女"
    },
    {
      "age": 7,
      "sex": "东方不败"
    },
    {
      "age": 20,
      "sex": "男"
    },
    {
      "age": 15,
      "sex": "女"
    }
  ]
}

Json文件我是保存在StreamingAssets 下的 textJson.json

c#脚本如下

    public string sex; 
}
public class Parsing_json : MonoBehaviour
{
    public string jsonpath = Application.streamingAssetsPath + "/textJson.json";
    // Start is called before the first frame update
    void Start()
    {
        #region 第一种unity自带解析的API  JsonUtility 读取Json
        //string json = File.ReadAllText(Application.streamingAssetsPath + "/textJson.json");
        //AA aa = JsonUtility.FromJson<AA>(json);

        //Debug.Log("年龄" + aa.name[0].age + "性别" + aa.name[0].sex);
        //Debug.Log("年龄" + aa.name[1].age + "性别" + aa.name[1].sex);

        #endregion

        #region 第二种 Newtonsoft.Json dll解析json  读取json

        //Debug.Log("年龄: " + obj.name[1].age + "性别: " + obj.name[1].sex);
        #endregion

        #region 创建json 保存到json文件
        //// 创建Json
        //BB p1 = new BB();
        //p1.sex = "不男不女";
        //p1.age = 28;
        //string json = JsonUtility.ToJson(p1);

        //BB p2 = new BB();
        //p2.sex = "东方不败";
        //p2.age = 7;
        //BB[] ps = new BB[] { p1, p2 };

        //AA persons = new AA();
        //persons.name = ps;

        //json = JsonUtility.ToJson(persons);
        //if (!System.IO.File.Exists (jsonpath))
        //{
        //    File.CreateText(jsonpath).Dispose();
        //}
        //File.WriteAllText(jsonpath, json, System.Text.Encoding.UTF8);

        #endregion
        //解析Json
        string jso = File.ReadAllText(jsonpath);
        AA obj = JsonUtility.FromJson<AA>(jso);

        foreach (var item in obj.name)
        {
            Debug.Log("年龄: " + item.age + "性别: " + item.sex);
        }

    }
  
}

最后警惕一下

如果打印出来的中文出现乱码

解决办法  在文件夹中用记事本打开json文件,另存为一下(改一下编码格式为UTF8即可)名字不用改它会自动覆盖原来的json文件

如果喜欢请点个赞吧 !  感谢
