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

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"u6253u5F00/u5173u95EDu7535u6E90u4E3Bu8DEFu8F93u51FA"
