Json反編譯從維基百科API與C＃

Question

我有一個與JSON格式的維基百科API。現在我想從這個API獲取提取信息。我想讓它對任何維基百科API都是動態的。 [我的維基百科api] [1]。我從jsontoCsharp

namespace Json_deserialize 
{ 
    public class pageval 
    { 
    public int pageid { get; set; } 
    public int ns { get; set; } 
    public string title { get; set; } 
    public string extract { get; set; } 
} 


public class Query 
{ 
    public Dictionary<string, pageval> pages { get; set; } 
} 

public class Limits 
{ 
    public int extracts { get; set; } 
} 

public class RootObject 
{ 
    public string batchcomplete { get; set; } 
    public Query query { get; set; } 
    public Limits limits { get; set; } 
} 

class Short_text 
    { 
    public static RichTextBox txt1 = new RichTextBox(); 
    public static void shortText() 
    { 
     using (WebClient wc = new WebClient()) 
     { 
      var client = new WebClient(); 
      var response = client.DownloadString("https://en.wikipedia.org/w/api.php?format=json&action=query&prop=extracts&exlimit=max&explaintext&exintro&titles=Neuschwanstein%20Castle&redirects="); ; 

      pageval m = JsonConvert.DeserializeObject<pageval>(response); 

      string result = m.extract; 

      txt1.Text = result; 
     } 

     } 

    } 

}

我想做出這樣的應該是動態編碼以下信息。這意味着id 240912應該及時更改。我嘗試了很多。但不能得到滿意的結果。

Answer 1

所有JSON對象本質上都是字典。但是，假定模式是常量，那麼將它們表示爲C＃中的類通常是有意義的。對於屬性名稱不總是相同的情況，不可能編寫一個類來表示對象;所以你多使用動態或字典

public class pageval 
{ 
    public int pageid { get; set; } 
    public int ns { get; set; } 
    public string title { get; set; } 
    public string extract { get; set; } 
} 


public class Query 
{ 
    public Dictionary<string, pageval> pages { get; set; } 
} 

public class Limits 
{ 
    public int extracts { get; set; } 
} 

public class RootObject 
{ 
    public string batchcomplete { get; set; } 
    public Query query { get; set; } 
    public Limits limits { get; set; } 
} 

要獲得提取物：

var response = client.DownloadString("https://en.wikipedia.org/w/api.php?format=json&action=query&prop=extracts&exlimit=max&explaintext&exintro&titles=Neuschwanstein%20Castle&redirects="); ; 

var responseJson = JsonConvert.DeserializeObject<RootObject>(response); 
var firstKey = responseJson.query.pages.First().Key; 
var extract = responseJson.query.pages[firstKey].extract;

我覺得像這樣的一些東西會工作，你

public class pageval 
{ 
    public int pageid { get; set; } 
    public int ns { get; set; } 
    public string title { get; set; } 
    public string extract { get; set; } 
} 


public class Query 
{ 
    public Dictionary<string, pageval> pages { get; set; } 
} 

public class Limits 
{ 
    public int extracts { get; set; } 
} 

public class RootObject 
{ 
    public string batchcomplete { get; set; } 
    public Query query { get; set; } 
    public Limits limits { get; set; } 
}
