如何在 C# 中将非齐次 json 转换为字典 <string,string>？

Question

我正在做一个项目，我想将 json 数据转换为字典，但问题是 json 是非同质的。我正在使用 newtonsoft.json

这里是 JSON:

[{
    '_type': 'StatsItem',
    'Noofpostcomments': 0,
    'URL': 'https: //www.website.com/',
    'posts': 1,
    'Brand': 'Halfords',
    'Likes': 24884,
    'movedTo': 'FB',
    'sharing': 0,
    'talked': 94,
    'following': '24757',
    'Date': '27-Mar-2018',
    'unpopular': 0,
    'ID': '2453'
},
{
    '_type': 'StatsItem',
    'qualify': 53,
    'URL': 'https: //www.website.com/',
    'post': 3,
    'Brand': 'Kwik',
    'Likes': 32339,
    'movedTo': 'FB',
    'share': 128,
    'talk': 542,
    'followers': '31824',
    'Date': '27-Mar-2018',
    'bands': 240,
    'ID': '2453'
},
{
    '_type': 'StatsItem',
    'luck': 0,
    'URL': 'https: //www.website.com/',
    'bites': 0,
    'Brand': 'SEAT',
    'likes': 5329114,
    'movedTo': 'FB',
    'shares': 0,
    'talking': 552,
    'Followers': '5300000',
    'Date': '27-Mar-2018',
    'bands': 0,
    'ID': '2453'
},
{
    '_type': 'StatsItem',
    'spoofs': 1,
    'URL': 'https: //www.website.com/',
    'security': 1,
    'Brand': 'Honda',
    'fixes': 184065,
    'movedTo': 'FB',
    'shares': 15,
    'chat': 4251,
    'follow': null,
    'Date': '27-Mar-2018',
    'discussed': 102,
    'ID': '2453'
}]

代码如下：

Dictionary<string, string> columnDictionary = JsonConvert.DeserializeObject<Dictionary<string, string>>(jsonString);

也试过

JObject result = JObject.Parse(jsonString);

出现异常

An unhandled exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.dll

Additional information: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'System.Collections.Generic.Dictionary`2[System.String,System.String]' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.

To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.

Path '', line 1, position 1.

我哪里出错了，解决方法是什么？

Answer 1

您可以将其解析为字典数组（或列表）：List<Dictionary<string, object>>

var list = JsonConvert.DeserializeObject<List<Dictionary<string, object>>>(jsonData);

foreach(var item in list)
{
    foreach(KeyValuePair<string, object> keyVal in item)
    {
        Console.WriteLine($"{keyVal.Key}: {keyVal.Value?.ToString()}");
    }
}

Answer 2

string responseString = @"[

json 描述了一些东西的数组，而不是一些东西的字典。首先尝试反序列化为对象数组，然后检查您在调试器中得到的内容，看看是否可以将其细化为更具体的类型对象。

此外，这是异端，但您也可以使用 System.Web.Extensions 中的 System.Web.Script.Serialization.JavaScriptSerializer，它更老更笨，可以帮助反序列化 'unknown typed json'
