XMLレスポンスをC＃オブジェクトに変換する - エラー（xmlns = ''>は期待していませんでした）

Question

私は、関連するトピックで指定されたヒントやトリックを成功させずに試してきました。

私はXML文字列をC＃クラスオブジェクトにデシリアライズできません。 <DepartureBoard xmlns=''> was not expected.

子要素 "Departure"をその属性を持つオブジェクトとして取り出し、そのオブジェクトをリストに追加したいと考えています。

これはAPIからXMLデータ応答（それが短く）です。

<?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> 

これは私が変換をしようとする方法である。

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; 
    } 

C＃クラスました「ペーストは特別」を使用して生成されます。

EDIT

感謝をmkysoftに応じて、私は今少し良く理解してだと思います。 ListからDepartureBoard-objectに変更すると、エラーは消えます。オブジェクトはDeparture配列をnullとして返します。 DepartureBoardオブジェクト内の「Departure」の配列にアクセスするにはどうすればよいですか？

Answer 1

XMLファイルはリストで始めることはできません。それはルート要素で開始する必要があります。 xmlファイルでは、DepartureBoardはルート要素で、Departureは配列です。クラスは、XMLファイルで以下のコードで正しく動作しています。

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