来自 appsettings 的 C# 强类型 ConfigurationBuilder List<object>

Question

真的很纠结这个 - 有这么难吗？！

我的应用程序设置中有一个简单的对象数组：

"AppSettings": {
    "Names": [
      {
        "Id": "1",
        "Name": "Mike"
      },
      {
        "Id": "2",
        "Name": "John"
      }    
    ]
}

然后我有一个class

public class AppSettings
{
    public List<Names> Names { get; set; } = new List<Names>();
}

public class Names
{
    public string Id { get; set; }
    public string Name { get; set; }
}

我在我的应用设置中看到：

var configuration = new ConfigurationBuilder()
                            .SetBasePath(Directory.GetCurrentDirectory())
                            .AddJsonFile("appSettings.json").Build();

var config = new AppSettings();

这就是问题所在：

config.Names = configuration.GetSection("AppSettings:Names") //<<<< what do I do here?

似乎都与 IConfigurationSection 相关联，但没有帮助。

使用 ConfigurationBinder.Get<T> 扩展从设置中获取整个对象图。

ConfigurationBinder.Get<T> binds and returns the specified type. ConfigurationBinder.Get<T> may be more convenient than using ConfigurationBinder.Bind. The following code shows how to use ConfigurationBinder.Get<T> with the AppSettings class:

//...

AppSettings config = configuration.GetSection("AppSettings").Get<AppSettings>();

//...
