如何从asp.net核心中的外部Json文件访问数据？

{
  "Data": {
    "Name": "John",
    "Age": 25,
    "Email": "john@example.com"
  }
}

public void ConfigureServices(IServiceCollection services)
{
    // 添加配置服务
    services.Configure<AppSettings>(Configuration.GetSection("Data"));
    // ...
}

public class AppSettings
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Email { get; set; }
}

public class HomeController : Controller
{
    private readonly AppSettings _appSettings;

    public HomeController(IOptions<AppSettings> appSettings)
    {
        _appSettings = appSettings.Value;
    }

    public IActionResult Index()
    {
        string name = _appSettings.Name;
        int age = _appSettings.Age;
        string email = _appSettings.Email;

        // 处理数据...

        return View();
    }
}
