使用二进制实现本地数据保存和读取（C# , Unity）

以二进制实现本地数据保存和读取，，，

项目中要存个本地文件，本来想使用Json 的，，可是怎么也没实现了，Json 好像只能存储string类型 -->（Dictionary<string, string> ）¹，，，没做出来，觉得XML读取费劲，最后决定使用二进制的形式存储为 .txt格式的，，，嗯，效果还可以，，，分享一下…

下面是存储和读取的代码：

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
using UnityEngine;
using UnityEngine.UI;

public class LobbyMiddleRightView : MonoBehaviour { public GameObject DownLoadObj; private string filePath; private LocalDataObject localDataObject  = new LocalDataObject(); /// <summary> /// 初始化 /// </summary> public void Init() { filePath = Application.dataPath + "/StreamingFile" + "/LocalData.txt"; localDataObject.iconPos.Add(1, "AAA"); localDataObject.iconPos.Add(2, "BBB"); localDataObject.iconPos.Add(3, "CCC"); localDataObject.iconPos.Add(4, "DDD"); localDataObject.iconPos.Add(5, "EEE"); localDataObject.iconPos.Add(6, "FFF"); localDataObject.isDownLoad.Add(1,true); localDataObject.isDownLoad.Add(2,true); localDataObject.isDownLoad.Add(3,true); localDataObject.isDownLoad.Add(4,true); localDataObject.isDownLoad.Add(5,true); localDataObject.isDownLoad.Add(6,true); } /// <summary> /// 以二进制形式 保存到本地 /// </summary> private void Save() { //二进制格式化程序 BinaryFormatter bf = new BinaryFormatter(); //创建流文件 FileStream fileStream = File.Create(filePath); //序列化 bf.Serialize(fileStream, localDataObject); fileStream.Close(); if (File.Exists(filePath)) { Debug.Log("保存成功"); } } /// <summary> /// 读取本地文件 /// </summary> private void Read() { if (File.Exists(filePath)) { BinaryFormatter bf = new BinaryFormatter(); FileStream filestream = File.Open(filePath, FileMode.Open); LocalDataObject localDataObject = (LocalDataObject)bf.Deserialize(filestream); filestream.Close(); Debug.Log("本地文件读取成功：  "); foreach (var key in localDataObject.iconPos.Keys) { Debug.Log(key + "  "+ localDataObject.iconPos[key]); } foreach (var key in localDataObject.isDownLoad.Keys) { Debug.Log(key + "  " + localDataObject.isDownLoad[key]); } } else { Debug.Log("不存在存档"); } }
}

/// <summary>
/// 本地数据对象
/// </summary>
[Serializable]
public class LocalDataObject
{ //使用Json，只能存储string类型 -->（Dictionary<string, string> ） public Dictionary<int, string> iconPos = new Dictionary<int, string>(); public Dictionary<int, bool> isDownLoad = new Dictionary<int, bool>();
}
