unity3d里的XML读写示例

关于U3D里面XML读写办法，谢谢刘老师的指导（刘国栋）

using UnityEngine;
using System.Collections;
using System.Xml;
using System.Xml.Serialization;
using System.IO;
using System.Text;
using System.Security.Cryptography;
using System;
public class XmlSaver
{

private static XmlSaver _Instance = null;
public static XmlSaver GetInstance()
{
if (_Instance == null)
{
_Instance = new XmlSaver();
}
return _Instance;
}
//内容加密
public string Encrypt(string toE)
{
//加密和解密采用相同的key,具体自己填，但是必须为32位//
byte[] keyArray = UTF8Encoding.UTF8.GetBytes("12348578902223367877723456789012");
RijndaelManaged rDel = new RijndaelManaged();

}

//内容解密
public string Decrypt(string toD)
{
//加密和解密采用相同的key,具体值自己填，但是必须为32位//
byte[] keyArray = UTF8Encoding.UTF8.GetBytes("12348578902223367877723456789012");

}

public string SerializeObject(object pObject,System.Type ty)
{

MemoryStream memoryStream = new MemoryStream();

}

//创建XML文件
public void CreateXML(string fileName,string thisData)
{
//string xxx = Encrypt(thisData);
string xxx = thisData;
StreamWriter writer;
writer = File.CreateText(fileName);
writer.Write(xxx);
writer.Close();
}

//读取XML文件
public string LoadXML(string fileName)
{

string dataString = sReader.ReadToEnd();
sReader.Close();
//string xxx = Decrypt(dataString);
string xxx = dataString;
return xxx;
}

//判断是否存在文件
public bool hasFile(String fileName)
{

}
public string UTF8ByteArrayToString(byte[] characters )
{

}

public byte[] StringToUTF8ByteArray(String pXmlString )
{

byte[] byteArray = encoding.GetBytes(pXmlString);
return byteArray;
}
}

后面是加载数据：

代码：

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public static class DataLoadTest{
public static List<Data> LevelData = new List<Data>();
//static string _fileName = Application.dataPath + "/Resource/gamedata";
static string _fileName = Application.persistentDataPath + "/gamedata";
public static void Save()
{
string s = XmlSaver.GetInstance().SerializeObject(LevelData, typeof(List<Data>));
XmlSaver.GetInstance().CreateXML(_fileName, s);
}
public static void Load()
{
try{
string s = XmlSaver.GetInstance().LoadXML(_fileName);
LevelData = XmlSaver.GetInstance().DeserializeObject(s, typeof(List<Data>)) as List<Data>;
}
catch {
TraverseList();
Save();
string s = XmlSaver.GetInstance().LoadXML(_fileName);
LevelData = XmlSaver.GetInstance().DeserializeObject(s, typeof(List<Data>)) as List<Data>;
}

}
public static void TraverseList()
{
List<ScrollData> everyScrollData = new List<ScrollData>();
everyScrollData.Add(new ScrollData(false, "挖掘机学校哪家强"));
everyScrollData.Add(new ScrollData(false, "中国山东找蓝翔"));
everyScrollData.Add(new ScrollData(false, "我特喵的只是开发者用来测试的"));

everyScrollData.Add(new ScrollData(false, "有我所不乐意的，在天堂里，我不愿意去；有我所不乐意的，在地狱里，我不愿意去； 有我所不乐意的，在你们的世界里，我不愿意去。 "));
everyScrollData.Add(new ScrollData(false, "我只愿蓬勃生活在此时此刻， 无所谓去哪，无所谓见谁。 那些我将要去的地方，都是我从未谋面的故乡； 那些我将要见的人，都会成为我的朋友。"));
everyScrollData.Add(new ScrollData(false, "以前是以前，现在是现在。 我不能选择 怎么生，怎么死； 但我能决定 怎么爱，怎么活。这是我要的自由，我的黄金时代。 "));

everyScrollData.Add(new ScrollData(false, "栈和队列的区别是啥？"));
everyScrollData.Add(new ScrollData(false, "吃多了拉就是队列；"));
everyScrollData.Add(new ScrollData(false, "吃多了吐就是栈"));

everyScrollData.Add(new ScrollData(false, "壮岁旌旗拥万夫，锦襜突骑渡江初。燕兵夜娖银胡簶，汉箭朝飞金仆姑。"));
everyScrollData.Add(new ScrollData(false, "追往事，叹今吾，春风不染白髭须。"));
everyScrollData.Add(new ScrollData(false, "却将万字平戎策，换得东家种树书。"));

everyScrollData.Add(new ScrollData(false, "第一天，小白兔去河边钓鱼，什么也没钓到，回家了。 "));
everyScrollData.Add(new ScrollData(false, "第二天，小白兔又去河边钓鱼，还是什么也没钓到，回家了。"));
everyScrollData.Add(new ScrollData(false, "第三天，小白兔刚到河边，一条大鱼从河里跳出来，冲着小白兔大叫：你他妈的要是再敢用胡箩卜当鱼饵，我就扁死你！"));

everyScrollData.Add(new ScrollData(false, "程序员的读书历程：x 语言入门 -> x 语言应用实践 -> x 语言高阶编程 -> "));
everyScrollData.Add(new ScrollData(false, "x 语言的科学与艺术 -> 编程之美 -> 编程之道 -> "));
everyScrollData.Add(new ScrollData(false, "编程之禅 -> 颈椎病康复指南 -> 精神病康复指南 "));

everyScrollData.Add(new ScrollData(false, "在一个精神病院里，有一天院长想看看三个精神病人的恢复情况如何，于是在他们每人面前放了一只小白兔。第一个精神病人坐在小白兔的上面，揪着小白兔的两只耳朵，
