我正在努力实现这样的目标：

• BaseSettings -具有所有其他部分通用的设置
• Child 1 Settings-具有所有BaseSettings + Child 1 Settings
• Child 2Settings-具有所有BaseSettings + Child 2Settings

[...]

• ChildNSettings -具有所有BaseSettings + ChildNSettings

所以我在我的控制器里有这个：

public class Child1Controller : Controller
{
    public Child1Controller(Child1Settings settings)
    {
        // settings.BaseSetting and settings.Child1Setting should both be accessible here
    }
}

我试过这个：

public class BaseSettings
{
    public string BaseSetting { get; set; }
}

public class Child1Settings : BaseSettings
{
    public string Child1Setting { get; set; }
}

appsettings.json

{
    "BaseSettings": {
        "BaseSetting": "BaseSettingValue"
    },
    "Child1Settings": {
        "Child1Setting": "Child1SettingValue"
    }
}

Startup.cs

public void ConfigureServices(IServiceCollection services)
{    
    services.AddOptions();
    services.Configure<Child1Settings>(options => Configuration.GetSection("Child1Settings").Get<Child1Settings>());
    services.AddSingleton(Configuration);
}

这可以很好地填充Child 1 Settings字段，但不能填充BaseSettings字段。我可以看到这个工作（虽然我没有尝试过），但这感觉很荒谬，如果我有很多孩子设置类，会导致很多冗余和潜在的错误：

appsettings.json

{
    "Child1Settings": {
        "BaseSettings": {
            "BaseSetting": "BaseSettingValue"
        }
        "Child1Setting": "Child1SettingValue"
    },
    "Child2Settings": {
        "BaseSettings": {
            "BaseSetting": "BaseSettingValue"
        }
        "Child2Setting": "Child2SettingValue"
    }
}
