XML 비 직렬화 시도시 빈 객체가 생성됩니다.

Question

콘솔 응용 프로그램에서 일부 XML을 비 직렬화하려고합니다. 데이터 중 일부만 신경 쓰면 필요한 필자만으로도 수업을 만들었습니다. 프로그램이 실행되지만 내가 비 직렬화하는 PetFinderPetRecord에는 모든 빈 멤버가 있습니다 (모든 문자열은 null이고 모든 int는 0입니다). 여기

콘솔 코드 : 여기

은 XML입니다

public class Class1 
{ 
    static void Main(string[] args) 
    { 
     string URL = "http://api.petfinder.com/pet.getRandom"; 
     string urlParameters = "?key=myprivatekey&id=ID123&status=A&format=xml&output=full"; 

     HttpClient client = new HttpClient(); 
     client.BaseAddress = new Uri(URL); 

     client.DefaultRequestHeaders.Accept.Add(
     new MediaTypeWithQualityHeaderValue("application/xml")); 

     HttpResponseMessage response = client.GetAsync(urlParameters).Result; 
     if (response.IsSuccessStatusCode) 
     { 
      XmlRootAttribute xRoot = new XmlRootAttribute(); 
      xRoot.ElementName = "petfinder"; 
      xRoot.IsNullable = true; 
      XmlSerializer serializer = new XmlSerializer(typeof(PetFinderPetRecord), xRoot); 

      PetFinderPetRecord record = null; 

      using (Stream stream = response.Content.ReadAsStreamAsync().Result) 
      { 
       record = (PetFinderPetRecord)serializer.Deserialize(stream); // <-- has empty members 
      } 
     } 
     else 
     { 
      Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase); 
     } 
    } 
} 

그리고 여기에 내가 역 직렬화하기 위해 노력하고있어 클래스에 :

[Serializable()] 
public class PetFinderPetRecord 
{ 
    [XmlElement("id")] 
    public int id { get; set; } 

    [XmlElement("shelterId")] 
    public int shelterId { get; set; } 

    [XmlElement("shelterPetId")] 
    public int shelterPetId { get; set; } 

    [XmlElement("name")] 
    public string name { get; set; } 

    [XmlElement("animal")] 
    public string animal { get; set; } 

    [XmlElement("mix")] 
    public string mix { get; set; } 

    [XmlElement("age")] 
    public string age { get; set; } 

    [XmlElement("sex")] 
    public string sex { get; set; } 

    [XmlElement("size")] 
    public string size { get; set; } 

    [XmlElement("description")] 
    public string description { get; set; } 

    [XmlElement("lastupdate")] 
    public DateTime lastupdate { get; set; } 

    [XmlElement("status")] 
    public string status; 

    public PetFinderPetRecord() 
    { 

    } 
} 

하는 경우 누군가 내가 놓친 것을 나에게 보여줄 수있었습니다. 내가 잘못하고있는 것을 보여 주면 크게 감사하게 생각합니다. 미리 감사드립니다. 이 유일한 문제이지만, 경우

Answer 1

확실하지 않은 코드 줄에 : 당신이 전화 기다리고해야

  HttpResponseMessage response = client.GetAsync(urlParameters).Result; 

: 그렇지

  HttpResponseMessage response = await client.GetAsync(urlParameters).Result; 

당신의이되기 전에 문을 실행할 수있는 경우 서버 응답

참고 :이 작업을 수행하려면 메서드 선언에 async 키워드를 추가해야합니다.

static void async Main(string[] args) 

나는 이것이이 안정적으로 문제를 재현 좋은, 간결-하지만-전체 코드 예제 있도록
