XML 응답을 C# 개체로 변환 중 - 오류 (xmlns = ''>이 (가) 예상하지 않음)

Question

나는 관련없는 주제로 지정된 많은 팁과 트릭을 성공 리에 시험해 보았습니다.

나는 XML 문자열을 C# 클래스 개체로 deserialise 할 수 없다. <DepartureBoard xmlns=''> was not expected.

"Departure"자식 요소를 특성이있는 개체로 가져 와서 목록에 개체를 추가하려고합니다.

는 API에서 XML 데이터의 응답이다 (이 짧게) :

public async Task<List<DepartureBoard>> GetDepartureBoard() 
    { 
     string url = "theApiUrlHere"; 
     HttpClient client = new HttpClient(); 
     string token = await oauth.RefreshToken(); 

     client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token); 
     HttpResponseMessage response = await client.GetAsync(url); 
     HttpContent content = response.Content; 
     HttpContentHeaders headers = response.Content.Headers; 

     byte[] mycontent = await response.Content.ReadAsByteArrayAsync(); 

     string xmlString = Encoding.Default.GetString(mycontent); 
     StringReader reader = new StringReader(xmlString); 

     List<DepartureBoard> result; 

     XmlSerializer xs = new XmlSerializer(typeof(List<DepartureBoard>), new XmlRootAttribute("Departure")); 

     result = (List<DepartureBoard>)xs.Deserialize(reader); 

     return result; 
    } 

는 C# 클래스했다 :

<?xml version="1.0" encoding="UTF-8"?> 
<DepartureBoard xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://api.vasttrafik.se/v1/hafasRestDepartureBoard.xsd" servertime="01:52" serverdate="2017-04-09"> 
    <Departure name="SJ REGIONAL" sname="TÅG" type="VAS" stopid="9022014081600002" stop="Trollhättan station, Trollhättan" time="14:07" date="2017-04-09" journeyid="9015074172200363" direction="Göteborg" track="2" rtTime="14:07" rtDate="2017-04-09" fgColor="#00A5DC" bgColor="#ffffff" stroke="Solid"> 
    <JourneyDetailRef ref="longUrlHere" /> 
    </Departure> 
    <Departure name="VÄSTTÅGEN" sname="TÅG" type="VAS" stopid="9022014081600002" stop="Trollhättan station, Trollhättan" time="14:22" date="2017-04-09" journeyid="9015014172103251" direction="Göteborg" track="2" rtTime="14:22" rtDate="2017-04-09" fgColor="#00A5DC" bgColor="#ffffff" stroke="Solid"> 
    <JourneyDetailRef ref="longUrlHere" /> 
    </Departure> 
</DepartureBoard>

감사를 mkysoft 편집, 나는 지금 조금 더 잘 이해 생각한다. List에서 DepartureBoard-object로 변경하면 오류가 사라집니다. 객체가 Departure 배열을 null로 반환하지만. DepartureBoard-object 내부의 "Departure"배열에 어떻게 액세스 할 수 있습니까? 목록을 시작할 수 없습니다

Answer 1

XML 파일, 그것은 루트 요소로 시작해야합니다. XML 파일에서 DepartureBoard는 루트 요소이고 Departure는 배열입니다. 클래스가 xml 파일과 함께 아래의 코드로 제대로 작동하고 있습니다.

DepartureBoard result; 
XmlSerializer xs = new XmlSerializer(typeof(DepartureBoard), new XmlRootAttribute("DepartureBoard")); 
result = (DepartureBoard)xs.Deserialize(reader);
