Json实体类

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

[System.Serializable]
public class StudentData
{
    public string StudentName;
    public string StudentGender;
    public string StudentAge;

}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using UnityEngine;

namespace Assets.UIFrameWork
{
    [System.Serializable]
   public class StudentDataItems
    {
        public StudentData[] infoList;
    }
}

Json

{
  "infoList": [
    {
      "StudentName": "张三",
      "StudentGender": "男",
      "StudentAge": "23"

    },
    {
      "StudentName": "李四",
      "StudentGender": "女",
      "StudentAge": "23"

    },
    {
      "StudentName": "王五",
      "StudentGender": "男",
      "StudentAge": "23"

    }
  ]
}

把Json文件放到名字为Resources的文件夹下

解析方法的代码

  public void ParseJsonToStr()
    {
        TextAsset ta = Resources.Load<TextAsset>("uiJson");
        byte[] ReadByte = Encoding.UTF8.GetBytes(ta.text);
        StudentDataItems dataItems = JsonUtility.FromJson<StudentDataItems>(UTF8Encoding.UTF8.GetString(ReadByte));
        foreach(StudentData studentData in dataItems.infoList)
        {
            Debug.Log("学生姓名为"+studentData.StudentName);
        }
        
    }

结果

注意事项

(1)用于接收的JSON实体类需要声明[Serializable] 序列化。
(2)使用Unity自带方法时,实体类如果是属性成员(public bool has_more{get;set;})的话,在序列化的时候会缺失这些成员,导致解析不出来。将属性改为字段即可。
(3)如何解析的对象是数组,自带的不能成功解析,可以人为将其封装为JSON对象。
