c# – 设计设置结构

我有一个问题,我想为我的应用程序设计一个在本地化,扩展和分组方面尽可能最佳的设置结构.我想按实体类型对设置进行分组(您可以将其视为每个控制器的分组设置).设置将显示给用户,因此每个设置都需要一个漂亮的标题和描述,这两者都需要本地化.新设置只会由开发人员引入,并且需要重新编译.

我想到的是一个将设置公开为静态属性的类,因此可以方便地以静态方式在整个应用程序中使用它们.第一次构造类时会加载设置(在请求设置时会发生这种情况),我使用数据库存储设置并使用反射在运行时将它们分配给相应的属性.

看起来像这样

public class FirmSettings
{
    private static IFirmSettingsRepository _repository { get; set; }

    public static bool ShowInvoicePaymentDetails { get; set; }

    public static bool ShowInvoiceDiscountValue { get; set; }

    public static bool ShowDocumentComment { get; set; }

    public static bool ShowDocumentTaxStatement { get; set; }

    public static bool ShowDocumentAuthor { get; set; }

    #region Constructors

    /// <summary>
    ///     Initializes a new instance of the <see cref = "FirmSettings" /> class.
    /// </summary>
    static FirmSettings()
    {
        Load();
    }

每个设置都存储在DB中作为属性名称的小写版本(对于加载我们忽略大小写).本地化字符串也是如此,它将被存储为例如FirmSettings_ShowDocumentTaxStatement_Title和FirmSettings_ShowDocumentTaxStatement_Desc. (惯例)

然而,这种方法不能解决分组问题.在UI中,将需要某种设置分组,因此发票设置将显示在组中.我可以为某些设置引入前缀,然后根据前缀(另一种约定)将其渲染出来.

你喜欢这种方法吗？如果没有,你是怎么做到的？这种方法有很多惯例,这就是困扰我的东西,只是一点点.
