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

我很熟悉将appsettings.json节加载到.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/值对的数量会有所不同和名称随着时间的流逝。因此，对类中的属性名称进行硬编码是不切实际的，因为新的键/值对将需要在类中进行代码更改。以下是一些键/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."
}

是否可以将这些数据加载到MobileConfigInfo Dictionary对象中，然后使用是否可以通过IOptions模式将MobileConfigInfo注入到控制器中？

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

您可以使用 Configuration.Bind（settings） ; 在 startup.cs 类中

您的设置类将类似于

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