游戏中往往需要存档和读档，进行游戏的保存和读取，游戏的存档和读档其实就是对象的序列化和反序列化。如果游戏中需要存储的类是Save，那么有三种方式进行存档和读档。

//数据类 [System.Serializable] public class Save { 
    public List<int> livingTargetPositions = new List<int>(); public List<int> livingMonsterTypes = new List<int>(); public int shootNum = 0; public int score = 0; }

    print("保存成功"); } //读取 BinaryFormatter bf = new BinaryFormatter(); //打开一个文件流 FileStream fileStream = File.Open(Application.dataPath + "/StreamingFile" + "/byBin.txt", FileMode.Open); //调用格式化程序的反序列化方法，将文件流转换为一个Save对象 Save save= (Data)bf.Deserialize(fileStream); //关闭文件流 fileStream.Close(); 

using LitJson; //Json方式 //存档 string filePath = Application.dataPath + "/StreamingFile" + "/byJson.json"; //利用JsonMapper将save对象转换为Json格式的字符串 string saveJsonStr = JsonMapper.ToJson(save); //将这个字符串写入到文件中 //创建一个StreamWriter，并将字符串写入文件中 StreamWriter sw = new StreamWriter(filePath); sw.Write(saveJsonStr); //关闭StreamWriter sw.Close(); print("保存成功"); //读档 //创建一个StreamReader，用来读取流 string filePath = Application.dataPath + "/StreamingFile" + "/byJson.json"; StreamReader sr = new StreamReader(filePath); //将读取到的流赋值给jsonStr string jsonStr = sr.ReadToEnd(); //关闭 sr.Close(); //将字符串jsonStr转换为Save对象 Save save = JsonMapper.ToObject<Save>(jsonStr); 

讯享网using System.Xml; //Xml方式 //存档 string filePath = Application.dataPath + "/StreamingFile" + "/byXML.txt"; //创建XML文档 XmlDocument xmlDoc = new XmlDocument(); //创建根节点，即最上层节点 XmlElement root = xmlDoc.CreateElement("save"); //设置根节点中的值 root.SetAttribute("name", "saveFile1"); //创建XmlElement XmlElement target; XmlElement targetPosition; XmlElement monsterType; //遍历save中存储的数据，将数据转换成XML格式 for(int i = 0; i < save.livingTargetPositions.Count; i++) { 
    target = xmlDoc.CreateElement("target"); targetPosition = xmlDoc.CreateElement("targetPosition"); //设置InnerText值 targetPosition.InnerText = save.livingTargetPositions[i].ToString(); monsterType = xmlDoc.CreateElement("monsterType"); monsterType.InnerText = save.livingMonsterTypes[i].ToString(); //设置节点间的层级关系 root -- target -- (targetPosition, monsterType) target.AppendChild(targetPosition); target.AppendChild(monsterType); root.AppendChild(target); } //设置射击数和分数节点并设置层级关系 xmlDoc -- root --(target-- (targetPosition, monsterType), shootNum, score) XmlElement shootNum = xmlDoc.CreateElement("shootNum"); shootNum.InnerText = save.shootNum.ToString(); root.AppendChild(shootNum); XmlElement score = xmlDoc.CreateElement("score"); score.InnerText = save.score.ToString(); root.AppendChild(score); xmlDoc.AppendChild(root); xmlDoc.Save(filePath); //读档 string filePath = Application.dataPath + "/StreamingFile" + "/byXML.txt"; Save save = new Save(); //加载XML文档 XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(filePath); //通过节点名称来获取元素，结果为XmlNodeList类型 XmlNodeList targets = xmlDoc.GetElementsByTagName("target"); //遍历所有的target节点，并获得子节点和子节点的InnerText if(targets.Count != 0) { 
    foreach(XmlNode target in targets) { 
    XmlNode targetPosition = target.ChildNodes[0]; int targetPositionIndex = int.Parse(targetPosition.InnerText); //把得到的值存储到save中 save.livingTargetPositions.Add(targetPositionIndex); XmlNode monsterType = target.ChildNodes[1]; int monsterTypeIndex = int.Parse(monsterType.InnerText); save.livingMonsterTypes.Add(monsterTypeIndex); } } //得到存储的射击数和分数 XmlNodeList shootNum = xmlDoc.GetElementsByTagName("shootNum"); int shootNumCount = int.Parse(shootNum[0].InnerText); save.shootNum = shootNumCount; XmlNodeList score = xmlDoc.GetElementsByTagName("score"); int scoreCount = int.Parse(score[0].InnerText); save.score = scoreCount;
