JsonUtility解析Json

---

JsonUtility是Unity官方的一个解析Json的API，下面是我定义的Json文件，记录了项目中的panle预制件名字和与其所在的路径。

{  "infoList":   [    {      "panelTypeString": "MainMenu",      "path": "UIPanel/MainMenuPanel"    },    {      "panelTypeString": "Task",      "path": "UIPanel/TaskPanel"    },    {      "panelTypeString": "Knapsack",      "path": "UIPanel/KnapsackPanel"    },    {      "panelTypeString": "Skill",      "path": "UIPanel/SkillPanel"    },    {      "panelTypeString": "Battle",      "path": "UIPanel/BattlePanel"    },    {      "panelTypeString": "System",      "path": "UIPanel/SystemPanel"    },    {      "panelTypeString": "KnapsackPop",      "path": "UIPanel/KnapsackPopPanel"    }  ]}

为了从json文件里面获取到相关的信息，需要做以下准备，代码如下：

using UnityEngine;using System;/// <summary>/// panel 信息类/// </summary>/// 注意这里需要加这个可序列化属性 [Serializable]，不然解析会报错[Serializable]public class PanelInfo:ISerializationCallbackReceiver {    [NonSerialized]    public UIPanelType panelType;    public string panelTypeString;    //{    //    get { return panelType.ToString(); }    //    set    //    {    //       UIPanelType type=(UIPanelType) System.Enum.Parse(typeof(UIPanelType), value);    //        panelType = type;    //    }    //}    public string path;    public void OnBeforeSerialize()    {    }    //反序列化=>从文本信息到对象    public void OnAfterDeserialize()    {        UIPanelType type = (UIPanelType)System.Enum.Parse(typeof(UIPanelType),panelTypeString);        panelType = type;    }}

 /// <summary>    /// 对应json文件里面的数组    /// </summary>    ///  [Serializable] 属性不可缺，不然会报错    [Serializable]    class UIPanelTypeJson    {        public List<PanelInfo> infoList;    }    /// <summary>    /// 解析json文件过程    /// </summary>    private void UIPanelPathParson()    {        panelPathDict = new Dictionary<UIPanelType, string>();        TextAsset uiPanelType = Resources.Load<TextAsset>("UIPanelType");        UIPanelTypeJson panelTypeJson= JsonUtility.FromJson<UIPanelTypeJson>(uiPanelType.text);        foreach (PanelInfo panelInfo in panelTypeJson.infoList)        {            Debug.Log(panelInfo.path);        }    }
