XML의 역 직렬화 오류 - 예상치 못한 '하는 endElement'

편집 : 사람이 솔루션을 찾고 여기에 오는 경우 - 코드가 아래에 업데이트되어 올바르게 .NET을 대상으로 C#을 사용 허용 대답XML의 역 직렬화 오류 - 예상치 못한 '하는 endElement'

덕분에 작동 4.5.3, C# 클래스 인스턴스에 웹 API REST XML 응답을 역 직렬화하려고합니다.

내 질문은 : 어떻게해야 할 일을하도록이 코드를 수정할 수 있습니까? XML 응답을 C# 클래스 인스턴스로 올바르게 역 직렬화합니다. 여기

Message: Error in line 1 position 226. 'EndElement' 'matchset' from namespace 'urn:expasy:scanprosite' is not expected. Expecting element 'n_match'.

xml이 유효하지 않습니까? 그렇습니다.'xmlns'는 ... 횡설수설입니까? 이것은 거의 확실히 XML 네임 스페이스와 관련이 있습니다. ''은 (는) ''또는 '과 동일하지 않습니다. 나는 당신이'xmlns = "urn : expasy : scanprosite"'를 의미한다고 생각하고있다. 또는...? –

@MarcGravell 스택 오버플로에 대해 들여 쓰기 탭을 만들기 위해 XML을 Visual Studio에 붙여 넣었습니다. 자동 서식 지정은 일부 텍스트를 변경해야합니다. 나는 그것을 지금 다시 붙여 넣었다. 그 점을 지적 해 주셔서 감사합니다. – Aalawlx

클래스에는 데이터 계약 속성과 XmlSerializer 속성이 혼합되어 있습니다. 나는 [XmlSerializerFormat] 속성의 응용 때문에 당신이 XmlSerializer을 사용하고 있다고 가정 할 것입니다.

이 matchset에 XmlRoot 속성을 다시 넣어 :이 경우, 다음을 수행해야

[Serializable] 
[XmlSerializerFormat] 
[DataContract(Name = "matchset", Namespace = "urn:expasy:scanprosite")] 
[XmlRoot(ElementName = "matchset", Namespace = "urn:expasy:scanprosite")] 
public class matchset 
{

변경 public match[] matchXmlElement에 :

[DataMember(Name = "match")] 
    [XmlElement("match")] 
    public match[] match 
    { 
     get { return this.matchField; } 
     set { this.matchField = value; }

내가 제안한 두 가지 변경 사항을 만들었지 만 동일한 예외가 여전히 발생합니까? 만약 당신이 그것을 가지고 있다면 - 전체 코드를 붙여 넣을 수있는 기회가 있습니까 아니면 다른 제안이 있습니까? 고맙습니다. – Aalawlx

일치 배열을 읽지 못했습니다. 클래스를 복사하고 디버깅 한 후에 "IsRequired"를 추가했습니다. 이제 다시 시작해야할까요? – dbc

예 일치 배열을 읽지는 않지만 속성을 읽지 않습니다. 그러나 제안 된 변경 사항을 적용해도 일치 배열이 읽히지 않았습니다. 그것만으로 개선 될 수 있습니다. – Aalawlx
