如何使用microsoft.extensions.configuration从配置文件中读取复杂对象

Question

我有以下配置文件

{
  "MyNamespace.Plugin": {
    "Setting": {
      "Path": "test"
    }
  }
}

并编写了以下代码来读取它

var config = new ConfigurationBuilder()
                .AddJsonFile("settings.json")
                .Build();

var configuration = config.GetSection("MyNamespace.Plugin");

Setting setting = configuration.GetValue<Setting>("Setting");

但是，对于setting，我总是得到null。我不确定我错在哪里。

我能够做到以下几点

var configuration = settings.Configuration.GetSection("MyNamespace.Plugin");

var settingSection = configuration.GetSection("Setting");
var setting = new Setting();
settingSection.Bind(setting);
