using Newtonsoft.Json;

读取Json

核心代码

                //核心代码using (StreamReader file = File.OpenText(filePath)){JsonSerializer serializer = new JsonSerializer();var ret = (类型)serializer.Deserialize(file, typeof(类型));}

示例

        Dictionary<string, double> LoadDictionaryFromFile(){Dictionary<string, double> ret = new Dictionary<string, double>();try{if (!Directory.Exists(folderPath)){//检查文件目录是否存在Directory.CreateDirectory(folderPath);}var filePath = Path.Combine(folderPath, FileName);if (!File.Exists(filePath)){File.Create(filePath);}else{//核心代码using (StreamReader file = File.OpenText(filePath)){JsonSerializer serializer = new JsonSerializer();ret = (Dictionary<string, double>)serializer.Deserialize(file, typeof(Dictionary<string, double>));}}}catch (Exception ex){MainDeviceProvider.Instance.Logger.Error("解析出现错误！",ex);}return ret;}

写入Json

核心代码

var filePath = Path.Combine(folderPath, FileName);string data = JsonConvert.SerializeObject(dataDictionary, Formatting.Indented);File.WriteAllText(filePath, data);

示例

void SaveDataToFile(){try{var filePath = Path.Combine(folderPath, FileName);string data = JsonConvert.SerializeObject(dataDictionary, Formatting.Indented);File.WriteAllText(filePath, data);}catch(Exception ex){MainDeviceProvider.Instance.Logger.Error("写入出现错误！", ex);}}
