如何将 appsetting.json 部分加载到 .NET Core 中的 Dictionary 中? [英] How to load appsetting.json section into Dictionary in .NET Core?

问题描述

我熟悉将 appsettings.json 部分加载到 .NET Core startup.cs 中的强类型对象中.例如:

I am familiar w/ loading an appsettings.json section into a strongly typed object in .NET Core startup.cs. For example:

public class CustomSection 
{
   public int A {get;set;}
   public int B {get;set;}
}

//In Startup.cs
services.Configure<CustomSection>(Configuration.GetSection("CustomSection"));

//Inject an IOptions instance
public HomeController(IOptions<CustomSection> options) 
{
    var settings = options.Value;
}

我有一个 appsettings.json 部分，其键/值对的数量和名称会随着时间的推移而变化.因此，在类中硬编码属性名称是不切实际的，因为新的键/值对需要在类中更改代码.一些键/值对的小样本:

I have an appsettings.json section who's key/value pairs will vary in number and name over time. Therefore, it's not practical to hard code property names in a class since new key/value pairs would require a code change in the class. A small sample of some key/value pairs:

"MobileConfigInfo": {
    "appointment-confirmed": "We've booked your appointment. See you soon!",
    "appointments-book": "New Appointment",
    "appointments-null": "We could not locate any upcoming appointments for you.",
    "availability-null": "Sorry, there are no available times on this date. Please try another."
}

有没有办法将这些数据加载到 MobileConfigInfo Dictionary 对象中，然后使用 IOptions 模式将 MobileConfigInfo 注入控制器?

Is there a way to load this data into a MobileConfigInfo Dictionary object and then use the IOptions pattern to inject MobileConfigInfo into a controller?

推荐答案

你可以在startup.cs类

你的设置类会像

public class AppSettings
{
    public Dictionary<string, string> MobileConfigInfo
    {
        get;
        set;
    }
}

希望能帮到你！
