使用具有随机根名称的C#反序列化JSON [英] Deserialize json with c# with random root names

问题描述

我有一个json文件，该文件的根中具有随机名称，但子元素中具有相同的结构.我想获取数组或列表中的所有子元素.

I have a json file which has random names in roots but same structure in child elements. I would like to get all the child elements in an array or a list.

示例json文件:

{  
   "-LeHl495vL6vh-8CaLbD":{  
      "apiKey":"sr-tr-137-beea04e44cb452ba0da0ca090b7e61b4ec6ffc69"
   },
   "-LeHl6jrhUEMb7slZcpB":{  
      "apiKey":"sr-tr-137-aef7a23095c0c7baef1ef681bdd8bf9756ac2a17"
   }
}

我已经尝试过这些课程，但不能做到.

I have tried these classes but could not do it.

public class RequestedReport
    {
        public Dictionary<string, List<ReportData>> ReportDatas { get; set; }
    }

    public class ReportData
    {
        public string apiKey { get; set; }
    }

所以我反序列化的预期输出就像List，其中包含json文件中的所有apiKeys.

So my expected output from deserialization is like List which contains all the apiKeys in json file.

谢谢.

推荐答案

在我看来，您的JSON直接表示Dictionary<string, ReportData>.没有包装对象，也没有列表.如果将JSON反序列化为该类型，那应该没问题.这是一个完整的示例:

It looks to me like your JSON represents a Dictionary<string, ReportData> directly. There's no wrapper object, and no lists involved. If you deserialize your JSON to that type, it should be fine. Here's a complete example:

using System;
using System.Collections.Generic;
using System.IO;
using Newtonsoft.Json;

class Program
{
    static void Main()
    {
        var json = File.ReadAllText("test.json");
        var reports = JsonConvert.DeserializeObject<Dictionary<string, ReportData>>(json);

        foreach (var pair in reports)
        {
            Console.WriteLine($"{pair.Key}: {pair.Value.ApiKey}");
        }
    }
}

public class ReportData
{
    [JsonProperty("apiKey")]
    public string ApiKey { get; set; }
}

如果您只想要API密钥列表，并且不关心与它们关联的字段名称，则可以使用:

If you just want the list of API keys, and you don't care about the field names associated with them, you can use:

var apiKeys = reports.Values.Select(x => x.ApiKey).ToList();
