我使用的维基百科api包含维基百科文章中所有地方的外部链接。我的维基百科api电话是: https://en.wikipedia.org/w/api.php?action=query&list=geosearch&gsradius=10000&gspage=Berlin&gslimit=500&gsprop=type|name|dim|country|region|globe&format=json

我使用JsonToCsharp为json对象创建c#类,如下所示:

  public class Geosearch
  {
    public int pageid { get; set; }
    public int ns { get; set; }
    public string title { get; set; }
    public double lat { get; set; }
    public double lon { get; set; }
    public double dist { get; set; }
    public string primary { get; set; }
    public string type { get; set; }
    public string name { get; set; }
    public object dim { get; set; }
    public string country { get; set; }
    public string region { get; set; }
  }

 public class Query
 {
   public List<Geosearch> geosearch { get; set; }
 }  

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

我的反序列化代码如下。使用此代码我只得到一个标题。但是我希望从这个api获得所有的头衔。我知道我应该制作一个foreach循环,但无法获得逻辑如何实现它。

static void Main(string[] args)
    {
        WebClient client = new WebClient();
        var GeoResponse = client.DownloadString("https://en.wikipedia.org/w/api.php?action=query&list=geosearch&gsradius=10000&gspage=Berlin&gslimit=500&gsprop=type|name|dim|country|region|globe&format=json");

        RootObject json = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<RootObject>(GeoResponse);

        var firstKey = json.query.geosearch.First().title;

        Console.WriteLine(firstKey);

    }

这很好用 -

var o = new HttpClient();
var res = new StreamReader(o.GetStreamAsync("https://en.wikipedia.org/w/api.php?action=query&list=geosearch&gsradius=10000&gspage=Berlin&gslimit=500&gsprop=type|name|dim|country|region|globe&format=json").Result).ReadToEnd() ;
var obj = JsonConvert.DeserializeObject<RootObject>(res).query.geosearch.Select(a => a.title).ToList();
// count == 500
obj.Foreach(a => Console.WriteLine(a));

我刚刚修改了我的代码,它运行正常。

 var response = client.GetAsync("https://en.wikipedia.org/w/api.php?action=query&list=geosearch&gsradius=10000&gspage=Berlin&gslimit=500&gsprop=type|name|dim|country|region|globe&format=json").Result;

            if (response.IsSuccessStatusCode)
            {

                var responseContent = response.Content;

                string responseString = responseContent.ReadAsStringAsync().Result;

                var obj = JsonConvert.DeserializeObject<RootObject>(responseString).query.geosearch.Select(a => a.title).ToList();

                foreach (var item in obj)
                {
                    Console.WriteLine(item);
                }
            }
        }
