XML의 자식 요소 만 필요로 할 때 객체에 대한 XML 응답을 비 직렬화 할 수 있습니까?

Question

나는 내가 WebRequest 클래스에서 다시 얻고 다음 XML했다 : 나는 다음과 같은 클래스를 생성 한

: 나는를 반환 내가 부르고 방법에

public class EventSearch 
{ 
    public int total_items { get; set; } 
    public int page_size { get; set; } 
    public int page_count { get; set; } 
    public int page_number { get; set; } 
    public int page_items { get; set; } 
    public string first_item { get; set; } 
    public string last_item { get; set; } 
    public string search_time { get; set; } 
    public List<Event> events { get; set; }

} 

을 원하는 이벤트 목록. 다음은 나에게 오류를 제공하는, 지금까지이 작업은 다음과 같습니다

was not expected.

코드 :

var request = WebRequest.Create(url); 
var response = request.GetResponse(); 

if (((HttpWebResponse)response).StatusCode == HttpStatusCode.OK) 
{ 
    // Get the stream containing content returned by the server. 
    Stream dataStream = response.GetResponseStream(); 
    // Open the stream using a StreamReader. 
    StreamReader reader = new StreamReader(dataStream); 

    XmlSerializer serializer = new XmlSerializer(typeof(EventSearch)); 
    EventSearch deserialized = (EventSearch)serializer.Deserialize(reader); 

    return deserialized.events; 
} 

나는 다음에 무엇을 모르겠어요. 내 수업에 주석을 달아야합니까?

Answer 1

예, classes에 Attributes을 추가하여 xml 요소를 개체에 매핑해야합니다.

이 작동합니다

, 그러나 나는 몇 가지를 변경했다, XML에서 날짜 시간이 잘못된 fromat에 그래서 나는 그것이 문자열, 또한 page_items는 int입니다 (필요에 따라 구문 분석 할 수 있습니다)했지만 그것은이다 xml의 ​​빈 요소는 비 직렬화 할 수 없으며 비어있을 가능성이있는 경우 문자열로 변경해야합니다.

using (FileStream stream = new FileStream("C:\\Test.xml", FileMode.Open)) 
{ 
    XmlSerializer serializer = new XmlSerializer(typeof(EventSearch)); 
    EventSearch deserialized = (EventSearch)serializer.Deserialize(stream); 
} 

그러나 Webresponce에서 Stream을 당신은 구별 할 필요가 :
