newtonnsoft JSON庫添加到Visual Studio和使用此代碼

WebClient webClient = new WebClient(); 
    webClient.OpenReadCompleted += new OpenReadCompletedEventHandler(downloadAboutCompleted); 
webClient.OpenReadAsync(new Uri("https://data.cityofchicago.org/api/views/xzkq-xp2w/rows.json?search=rahm"), c); 

private void downloadAlbumCompleted(object sender, OpenReadCompletedEventArgs e) 
     { 
      if (e.Error == null && !e.Cancelled) 
      { 
       using (StreamReader httpwebStreamReader = new StreamReader(e.Result)) 
       { 
        var results = httpwebStreamReader.ReadToEnd(); 
       System.Diagnostics.Debug.WriteLine(results): 
        var json = JObject.Parse(results); 
       System.Diagnostics.Debug.WriteLine(json): 

        foreach (JObject array in json["meta"]["view"]) 
        { 
         JObject obj = JObject.Parse(array.ToString()); 
         string id= (string)obj["id"]; 
         string name= (string)obj["name"]; 

       System.Diagnostics.Debug.WriteLine(id + name): 
        } 

       } 

      } 
     }
