[英]C# Deserilize from xml to object (<result xmlns=''> was not expected.)
[英]Converting XML response to C# object - Error ( xmlns=''> was not expected )
我一直在尝试一堆在相关主题中指定的技巧和窍门,但没有成功。
由于某种原因,我无法将XML字符串反序列化为C#类对象。 我因以下错误而晋升: <DepartureBoard xmlns=''> was not expected.
我想获取子元素“ Departure”作为具有其属性的对象,并将对象添加到列表中。
这是来自API的XML数据响应(简化了):
<?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>
这是我尝试进行转换的方法:
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#类是使用“特殊粘贴”生成的。

谢谢,我想我现在懂多了。 当我从列表更改为一个DepartureBoard对象时,错误消失了。 尽管该对象将Departure-array返回为null。 如何访问DepartureBoard对象内部的“ Departure”数组?
最佳/ J
Xml文件不能以list开头,它需要以root元素开头。 在您的xml文件中,DepartureBoard是根元素,Departure是一个数组。 您的班级正在使用带有xml文件的以下代码正常工作。
DepartureBoard result;
XmlSerializer xs = new XmlSerializer(typeof(DepartureBoard), new XmlRootAttribute("DepartureBoard"));
result = (DepartureBoard)xs.Deserialize(reader);
