C#字典序列化为Json字符串并写入文件
using System.Text.Json; using System.IO; using System.Text; public static Dictionary<Byte, Command> Commandss = new Dictionary<Byte, Command>(); public static string fileName = "temp"; public class Command { public Byte command { get; set; } public string name { get; set; } public string datatype { get; set; } public UInt16 datalength { get; set; } public string dataformat { get; set; } public Double coefficient { get; set; } public Double minValue { get; set; } public Double maxValue { get; set; } public Double defValue { get; set; } public string unit { get; set; } public string checktype { get; set; } public bool showState { get; set; } public Double Value { get; set; } } private void writeFile() { string jsonstr = JsonSerializer.Serialize(Commandss); string path = System.IO.Directory.GetCurrentDirectory() + fileName + "pmb"; if (!File.Exists(path)) { File.WriteAllText(path, jsonstr, Encoding.UTF8); } } private void readFile() { string path = System.IO.Directory.GetCurrentDirectory() + fileName + "pmb"; string jsonstr = File.ReadAllText(path); Commandss = JsonSerializer.Deserialize<Dictionary<Byte, Command>>(jsonstr); }
使用using System.Text.Json;前需安装对应的库文件
打开NuGet控制台,输入:dotnet add package System.Text.Json --version 5.0.1
参考:

遗留问题:
1.最早尝试的是对List(元素为结构体)进行序列化,序列化后数据全部丢失,原因未找到
2.转为Json字符串后,中文字符被转为"\u6253\u5F00/\u5173\u95ED\u7535\u6E90\u4E3B\u8DEF\u8F93\u51FA"
