在.NETCore控制台应用程序中使用强类型配置

public class MySettings
{
    public string ApplicationName { get; set; } 
}

public class MyModuleSettings
{
    public string ModuleName { get; set; }
}

{
  "ApplicationName": "My sample application",

  "SectionA": {
    "ModuleName": "My sample module"
  }
}

public class Program
{
    public static void Main(string[] args)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
            .AddEnvironmentVariables();

        IConfigurationRoot configuration = builder.Build();

        var settings = new MySettings();
        configuration.Bind(settings);

        var moduleSettings = new MyModuleSettings();
        configuration.GetSection("SectionA").Bind(moduleSettings);

        Console.WriteLine($"My application name is ‘{settings.ApplicationName}‘");
        Console.WriteLine($"My module name is ‘{moduleSettings.ModuleName}‘");

        Console.ReadLine();
    }
