... mais je suis incapable de convertir en DataTable en .Net

Je dois convertir la réponse en DataSet. Voici mes classes que j'ai utilisées lors de la conversion de la réponse. Je sais que nous convertissons facilement la réponse dans la liste, mais le problème se pose lorsque nous convertissons la réponse en données ou en données qui a une solution? J'ai essayé de convertir en 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; } 
    public string href { 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; 
    } 
} 

Answer 1

Je ne sais pas exactement ce que vous voulez faire comme vous ne l'avez pas affiché et la structure d'ensemble de données dans laquelle vous souhaitez analyser, mais, si vous créez suivre des cours, je pense vous pouvez analyser votre contenu JSON dans le modèle d'objet Query.

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; 

}
