C#读取Json配置文件

1、安装NuGet包：Newtonsoft.Json

2、新建Confgi.json

{
  "K-Fins": -1,
  "K-Zs" : 0.2,
}

3、在Models文件中新建AppConfig.cs和ConfigManager.cs

    public class AppConfig
    {
        public double KFins { get; set; }
        public double kZs { get; set; }
    }

    using Newtonsoft.Json;
　　 using System.IO;

public static class ConfigManager
    {
        public static AppConfig appConfig { get; private set; }

         static ConfigManager()
        {
            LoadConfig();
        }

        private static void LoadConfig()
        {
            var json = File.ReadAllText("Helper/AppConfig.json");
            appConfig = JsonConvert.DeserializeObject<AppConfig>(json);
        }

    }

 4、调用

double KFins = ConfigManager.appConfig.KFins;
