如何用值列表读取 appsettings.json？

Question

我有以下 appSettings.json 文件

  "UrlManagement": {
   "UrlList": [ 
   {
        "Microsoft":{
            "resource":"xyz",
             type": "iot"
        }, 

        "AWS":{
            "resource":"abc",
             "type": "storage"
        },     
   }]
  }
 }

我有class

public class UrlManagement
{
    public string CompanyName;
    public URLList UrlList;
}

public class URLList 
{
     public string Resource;
     public string Type;
}

我正在尝试获取这些值，如下所示

  private List<string> GetConfigurationDictionary()
  {
        var items = this._configuration.GetSection("UrlManagement:UrlList:0").
            GetChildren().ToDictionary(x => x.Key, x => x.Value);
  }

我得到 x.Value

的空值

您可以搜索UrlManagement:UrlList:0部分，如以下代码：

private List<UrlManagement> GetConfigurationDictionary()
{
    List<UrlManagement> result = this._configuration
        .GetSection("UrlManagement:UrlList:0")
        .GetChildren()
        .ToDictionary(x => x.Key, x => x.Get<UrlList>())
        .Select(x => new UrlManagement { CompanyName = x.Key, UrlList = x.Value })
        .ToList();

    return result;
}

演示

foreach (var item in result)
{
    Console.WriteLine($"{item.CompanyName} ==> {item.UrlList.Type}:{item.UrlList.Resource}");
}

结果

AWS ==> storage:abc
Microsoft ==> iot:xyz

我希望这可以帮助您解决问题
