Csharp ASP.NET从应用程序设置中获取整个对象

如果我有以下设置，有没有办法从Program.cs内请求设置.

appsettings.json:

{
  "Settings": {
    "UseMemory": false,
    "Cors": {
      "Origins": "*",
      "Headers": "*",
      "Methods": "*"
    }
  }
}

设置型号:

public class AppSettings
{
    public bool? UseMemory { get; set; }
    public CorsSettings? Cors { get; set; }
}

public class CorsSettings
{
    public required string Origins { get; set; }
    public required string Headers { get; set; }
    public required string Methods { get; set; }
}

这些都是我的try ，但设置始终是null(Program.Main内)

var builder = WebApplication.CreateBuilder(args);
var appSettings = builder.Configuration.GetRequiredSection("Settings");
builder.Services.Configure<Models.AppSettings>(appSettings);
...
var settings = builder.Configuration.Get<Models.AppSettings>(); // { UseMemory: null, Cors: null }

var builder = WebApplication.CreateBuilder(args);
var settings = builder.Configuration.GetValue<Models.AppSettings>("Settings"); // null
var settingsText = builder.Configuration.GetValue<string>("Settings"); // null

这很"管用"，但我希望找到一种方法，将所有设置放在一个整齐的对象中:

var builder = WebApplication.CreateBuilder(args);
var settingsText = builder.Configuration.GetSection("Settings").GetValue<string>("UseMemory"); // false
