C# 将分层列表转换为数据表/数据集

我有一个JSON：

…但我无法在

.Net

我需要将响应转换为

数据集

下面是我在转换响应时使用的类。我知道我们很容易在列表中转换响应，但当我们将响应转换为datatable或dataset时，问题就出现了。谁有任何解决方案？我已尝试将其转换为datatable

public class YahooImg
{
    public string alt { get; set; }
    [JsonProperty("data-file-height")]
    public string data_file_height { get; set; }
    [JsonProperty("data-file-width")]
    public string data_file_width { get; set; }
    public string height { get; set; }
    public string src { get; set; }
    public string srcset { get; set; }
    public string width { get; set; }
}
public class YahooData

    [JsonProperty("class")]
    public string CLASS { get; set; }

    [JsonProperty("Img")]
    public YahooImg img { get; set; }
    public string title { get; set; }
    public string content { get; set; }
    public string rel { get; set; }
    public List<string> span { get; set; }
    public List<object> wbr { get; set; }
}
public class YahooResults
{
    [JsonProperty("A")]
    public List<YahooData> a { get; set; }
}
public class YahooQuery
{
    public int count { get; set; }
    public string created { get; set; }
    public string lang { get; set; }
    [JsonProperty("Results")]
    public YahooResults results { get; set; }
}
public class YahooAPIData
{
    [JsonProperty("query")]
    public YahooQuery Yahooquery { get; set; }
    public YahooQuery GetYahooResult(string url)
    {
        var ds = new YahooAPIData();
        if (!url.ToLower().Contains("yahoo"))
            return ds.Yahooquery;
        try
        {
            var wc = new WebClient();
            wc.Headers.Add(HttpRequestHeader.Accept, "application/json");
            var response = wc.DownloadString(url);
           var dss = JsonConvert.DeserializeObject<YahooAPIData>(response);               
        }
        catch (Exception exp)
        {
            var r = exp;
        }
        return ds.Yahooquery;
    }
}

}
返回ds.Yahooquery；
}
}  

我不确定您到底想做什么，因为您还没有发布要解析的数据集结构，但是，如果您创建以下类，我认为您可以在查询对象模型中解析JSON内容

public class Query
{
    int count;
    datetime created;
    string lang;
    Result[] a; 
}

public class Result
{

    string _class;
    string href;
    Image img;

}

public class Image
{

    string alt;
    string data_file_height;
    string data_file_width;
    string height;
    string src;
    string srcset;
    string width;

}

请不要链接到外部网站，除非它是为了支持您问题中已经存在的内容。您确实需要删除

捕获（异常exp）

-捕获这样的内容是不好的做法。您还需要处理

WebClient

。您至少可以演示如何将JSON转换为此对象模型吗？顺便说一句，现在还没有编译。@Trikaldarshi我有和你提到的相同的类结构。我将json转换为列表问题是当我将结果列表转换为数据表时，因为列表具有层次数据。@Enigmativity：有几个库可用于将json转换为对象模型viz。Json，这取决于你想要使用什么。我已经试着做了转换。我做不到。这个答案并没有以当前的形式解决这个问题。答案的第一行清楚地提到了这一点，它只提供了一个可以解析json字符串的C#对象模型。
