public class MyArray : List<string> { }

services.Configure<ShipmentDetailsDisplayGidRoles>(Configuration.GetSection("MyArray"));

public SomeController(IOptions<MyArray> myArrayOptions)
{
    myArray = myArrayOptions.Value;
}

你可以像这样使用Microsoft.Extensions.Configuration.Binder包:

在你的appsettings.json中

{
      "MyArray": [
          "str1",
          "str2",
          "str3"
      ]
}

创建保存配置的对象:

 public class MyConfig
 {
     public List<string> MyArray { get; set; }
 }

在你的控制器绑定配置:

public class HomeController : Controller
{
    private readonly IConfiguration _config;
    private readonly MyConfig _myConfig = new MyConfig();

    public HomeController(IConfiguration config)
    {
        _config = config;
    }

    public IActionResult Index()
    {
        return Json(_config.Bind(_myConfig));
    }
}

你可以直接获得数组，而不需要在配置中增加一个新的级别:

public void ConfigureServices(IServiceCollection services) {
    services.Configure<List<String>>(Configuration.GetSection("MyArray"));
    //...
}

对于从配置返回复杂JSON对象数组的情况，我调整了@djangojazz的答案，以使用匿名类型和动态而不是元组。

给定的设置部分:

"TestUsers": [
{
  "UserName": "TestUser",
  "Email": "Test@place.com",
  "Password": "P@ssw0rd!"
},
{
  "UserName": "TestUser2",
  "Email": "Test2@place.com",
  "Password": "P@ssw0rd!"
}],

你可以这样返回对象数组:

public dynamic GetTestUsers()
{
    var testUsers = Configuration.GetSection("TestUsers")
                    .GetChildren()
                    .ToList()
                    .Select(x => new {
                        UserName = x.GetValue<string>("UserName"),
                        Email = x.GetValue<string>("Email"),
                        Password = x.GetValue<string>("Password")
                    });

    return new { Data = testUsers };
}

从appsettings.json中获取所有section的所有值

        public static string[] Sections = { "LogDirectory", "Application", "Email" };
        Dictionary<string, string> sectionDictionary = new Dictionary<string, string>();

        List<string> sectionNames = new List<string>(Sections);
        
        sectionNames.ForEach(section =>
        {
            List<KeyValuePair<string, string>> sectionValues = configuration.GetSection(section)
                    .AsEnumerable()
                    .Where(p => p.Value != null)
                    .ToList();
            foreach (var subSection in sectionValues)
            {
                sectionDictionary.Add(subSection.Key, subSection.Value);
            }
        });
        return sectionDictionary;

灯塔3.1

Json配置:

"TestUsers": 
{
    "User": [
    {
      "UserName": "TestUser",
      "Email": "Test@place.com",
      "Password": "P@ssw0rd!"
    },
    {
      "UserName": "TestUser2",
      "Email": "Test2@place.com",
      "Password": "P@ssw0rd!"
    }]
}

然后创建一个User.cs类，它具有与上面Json配置中的User对象对应的auto属性。然后你可以引用Microsoft.Extensions.Configuration.Abstractions并执行以下操作:

List<User> myTestUsers = Config.GetSection("TestUsers").GetSection("User").Get<List<User>>();
