asp.net core appsetting.json 绑定读取

appsettings.json中，具有：

"AppSettings": {
   "AzureConnectionKey": "***",
   "AzureContainerName": "**",
   "NumberOfTicks": 621355968000000000,
   "NumberOfMiliseconds": 10000,
   "SelectedPvInstalationIds": [ 13, 137, 126, 121, 68, 29 ],
   "MaxPvPower": 160,
   "MaxWindPower": 5745.35
},

我也有用于存储它们的类：

public class AppSettings
{
    public string AzureConnectionKey { get; set; }
    public string AzureContainerName { get; set; }
    public long NumberOfTicks { get; set; }
    public long NumberOfMiliseconds { get; set; }
    public int[] SelectedPvInstalationIds { get; set; }
    public decimal MaxPvPower { get; set; }
    public decimal MaxWindPower { get; set; }
}

然后启用DI，然后在Startup.cs中使用：

services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));

有没有什么办法来改变和保存MaxPvPower，并MaxWindPower从控制器？

我尝试使用

private readonly AppSettings _settings;

public HomeController(IOptions<AppSettings> settings)
{
    _settings = settings.Value;
}
