[csharp] view plain copy print ? //命名空间 using System.IO; using System.Collections.Generic; using LitJson; [csharp] view plain copy print ? //相关变量声明: private static string mFolderName; private static string mFileName; private static Dictionary<string, string> Dic_Value = new Dictionary<string, string>(); private static string FileName { get { return Path.Combine(FolderName, mFileName); } } private static string FolderName { get { return Path.Combine(Application.persistentDataPath, mFolderName); } } [csharp] view plain copy print ? //初始化方法 如有需要,可重载初始化方法 public static void Init(string pFolderName, string pFileName) { mFolderName = pFolderName; mFileName = pFileName; Dic_Value.Clear(); Read(); } [csharp] view plain copy print ? //读取文件及json数据加载到Dictionary中 private static void Read() { if(!Directory.Exists(FolderName)) { Directory.CreateDirectory(FolderName); } if(File.Exists(FileName)) { FileStream fs = new FileStream(FileName, FileMode.Open); StreamReader sr = new StreamReader(fs); JsonData values = JsonMapper.ToObject(sr.ReadToEnd()); foreach(var key in values.Keys) { Dic_Value.Add(key, values[key].ToString()); } if(fs != null) { fs.Close(); } if(sr != null) { sr.Close(); } } } [csharp] view plain copy print ? //将Dictionary数据转成json保存到本地文件 private static void Save() { string values = JsonMapper.ToJson(Dic_Value); Debug.Log(values); if(!Directory.Exists(FolderName)) { Directory.CreateDirectory(FolderName); } FileStream file = new FileStream(FileName, FileMode.Create); byte[] bts = System.Text.Encoding.UTF8.GetBytes(values); file.Write(bts,0,bts.Length); if(file != null) { file.Close(); } } 到此,简单的保存方法基本完成了。
[csharp] view plain copy print ? //判断当前是否存在该key值 public static bool HasKey(string pKey) { return Dic_Value.ContainsKey(pKey); } [csharp] view plain copy print ? //读取string值 public static string GetString(string pKey) { if(HasKey(pKey)) { return Dic_Value[pKey]; } else { return string.Empty; } } [csharp] view plain copy print ? //保存string值 public static void SetString(string pKey, string pValue) { if(HasKey(pKey)) { Dic_Value[pKey] = pValue; } else { Dic_Value.Add(pKey, pValue); } Save(); }
