c#-DataContract反序列化XML-同一元素中的元素和属性列表
作者：互联网
我在c#ASP.NET环境中工作.我试图将以下XML元素反序列化为c#对象/类.元素深3层.
<Availability>
<RecommendedSegment>
<Duration>1720</Duration>
<FareBasis>Y77OW</FareBasis>
<FlightSegment>
<DepDate>11 August</DepDate>
<DepTime>0830</DepTime>
<ArrDate>11 August</ArrDate>
<ArrTime>1110</ArrTime>
<DepDay>Mon</DepDay>
<ArrDay>Mon</ArrDay>
<DepAirport>LHR</DepAirport>
<DepAirportName>Heathrow</DepAirportName>
<DepCityName>London</DepCityName>
<ArrAirport>FRA</ArrAirport>
<ArrAirportName>Frankfurt Int'l</ArrAirportName>
<ArrCityName>Frankfurt</ArrCityName>
<DepCountry>United Kingdom</DepCountry>
<ArrCountry>Germany</ArrCountry>
<Airline>LH</Airline>
<AirName>Lufthansa</AirName>
<FlightNo>925</FlightNo>
<BookingClass>Y</BookingClass>
<AirCraftType>32A</AirCraftType>
<ETicket>Y</ETicket>
<NonStop>0</NonStop>
<DepTer>1</DepTer>
<ArrTer>1</ArrTer>
<AdtFareBasis>Y77OW</AdtFareBasis>
<ChdFareBasis>
</ChdFareBasis>
<InfFareBasis>
</InfFareBasis>
</FlightSegment>
<FlightSegment>
<DepDate>11 August</DepDate>
<DepTime>1330</DepTime>

<DepAirport>FRA</DepAirport>
<DepAirportName>Frankfurt Int'l</DepAirportName>
<DepCityName>Frankfurt</DepCityName>
<ArrAirport>BOM</ArrAirport>
<ArrAirportName>Bombay</ArrAirportName>
<ArrCityName>Mumbai</ArrCityName>
<DepCountry>Germany</DepCountry>
<ArrCountry>India</ArrCountry>
<Airline>LH</Airline>
<AirName>Lufthansa</AirName>
<FlightNo>756</FlightNo>
<BookingClass>Y</BookingClass>
<AirCraftType>744</AirCraftType>
<ETicket>Y</ETicket>
<NonStop>0</NonStop>
<DepTer>1</DepTer>
<ArrTer>2</ArrTer>
<AdtFareBasis>Y77OW</AdtFareBasis>
<ChdFareBasis>
</ChdFareBasis>
<InfFareBasis>
</InfFareBasis>
</FlightSegment>
<FlightSegment>
<DepDate>12 August</DepDate>
<DepTime>0515</DepTime>
<ArrDate>12 August</ArrDate>
<ArrTime>0620</ArrTime>
<DepDay>Tue</DepDay>
<ArrDay>Tue</ArrDay>
<DepAirport>BOM</DepAirport>
<DepAirportName>Bombay</DepAirportName>
<DepCityName>Mumbai</DepCityName>
<ArrAirport>GOI</ArrAirport>
<ArrAirportName>Dabolim</ArrAirportName>
<ArrCityName>Goa</ArrCityName>
<DepCountry>India</DepCountry>
<ArrCountry>India</ArrCountry>
<Airline>AI</Airline>
<AirName>Air India</AirName>
<FlightNo>984</FlightNo>
<BookingClass>Y</BookingClass>
<AirCraftType>321</AirCraftType>
<ETicket>Y</ETicket>
<NonStop>0</NonStop>
<DepTer>2</DepTer>
<ArrTer>
</ArrTer>
<AdtFareBasis>Y</AdtFareBasis>
<ChdFareBasis>
</ChdFareBasis>
<InfFareBasis>
</InfFareBasis>
</FlightSegment>
<DepAirport>LHR</DepAirport>
<DepCity>LON</DepCity>
<DepCountry>GB</DepCountry>
<DepZone>1</DepZone>
<ArrAirport>GOI</ArrAirport>
<ArrCity>GOI</ArrCity>
<ArrCountry>IN</ArrCountry>
<ArrZone>5</ArrZone>
</RecommendedSegment>
</Availability>
我试图捕获以下也是3级深的对象中的数据；
[DataContract(Name = "Availability")]
public class Availability
{
[DataMember(Name = "RecommendedSegment", Order = 0)]
public RecommendedSegment RecommendedSegment;
[DataMember(Name = "RecommendedSegment", Order = 1)]
public RecommendedSegmentFlights RecommendedSegmentFlights;
}
当我运行代码时,出现以下异常；
"ExceptionMessage":"Type 'Availability' contains two members 'RecommendedSegment' 'and 'RecommendedSegmentFlights' with the same data member name 'RecommendedSegment'. Multiple members with the same name in one type are not supported. Consider changing one of the member names using DataMemberAttribute attribute."
我了解到使用DataContract无法正常工作.有没有一种方法可以将“ FlightSegment”元素作为列表捕获到RecommendationSegmentFlights中？我已经阅读过,我需要使用以下任一方法来覆盖默认的序列化行为
[OnDeserialized]
void OnDeserialized(StreamingContext c)
{
if (MyCustonObj == null)
{
MyCustonObj = new MyCustomClass();
MyCustonObj.MyStrData = "Overridden in serialization";
}
}
[OnDeserializing]
void OnDeserializing(StreamingContext c)
{
if (MyCustonObj == null)
{
MyCustonObj = new MyCustomClass();
MyCustonObj.MyStrData = "Overridden in deserializing";
}
}
[OnSerialized]
void OnSerialized(StreamingContext c)
{
// if you wan to do somehing when serialized here or just remove them
}
[OnSerializing]
void OnSerializing(StreamingContext c)
{
// if you wan to do somehing during serializing here or just remove them
}
我该怎么办？我想要的只是该类中的属性RecommendationSegmentFlights,以包含FlightSegment元素的列表.我也不介意它是否是RecommendationSegment的子代.对于RecommendationSegmentFlights属性,我有这个；
public class RecommendedSegmentFlights : List<FlightSegmentStructure> { }
谢谢.
解决方法:
试试这个…(使用XmlSerializer而不是DataContractSerializer)
正在使用…
using System;
using System.Xml.Serialization;
using System.Collections.Generic;
using System.IO;
类…(使用http://xmltocsharp.azurewebsites.net/从XML创建)
[XmlRoot(ElementName = "FlightSegment")]
public class FlightSegment
{
[XmlElement(ElementName = "DepDate")]
public string DepDate { get; set; }
[XmlElement(ElementName = "DepTime")]
public string DepTime { get; set; }
[XmlElement(ElementName = "ArrDate")]
public string ArrDate { get; set; }
[XmlElement(ElementName = "ArrTime")]
public string ArrTime { get; set; }
[XmlElement(ElementName = "DepDay")]
public string DepDay { get; set; }
[XmlElement(ElementName = "ArrDay")]
public string ArrDay { get; set; }
[XmlElement(ElementName = "DepAirport")]
public string DepAirport { get; set; }
[XmlElement(ElementName = "DepAirportName")]
public string DepAirportName { get; set; }
[XmlElement(ElementName = "DepCityName")]
public string DepCityName { get; set; }
[XmlElement(ElementName = "ArrAirport")]
public string ArrAirport { get; set; }
[XmlElement(ElementName = "ArrAirportName")]
public string ArrAirportName { get; set; }
[XmlElement(ElementName = "ArrCityName")]
public string ArrCityName { get; set; }
[XmlElement(ElementName = "DepCountry")]
public string DepCountry { get; set; }
[XmlElement(ElementName = "ArrCountry")]
public string ArrCountry { get; set; }
[XmlElement(ElementName = "Airline")]
public string Airline { get; set; }
[XmlElement(ElementName = "AirName")]
public string AirName { get; set; }
[XmlElement(ElementName = "FlightNo")]
public string FlightNo { get; set; }
[XmlElement(ElementName = "BookingClass")]
public string BookingClass { get; set; }
[XmlElement(ElementName = "AirCraftType")]
public string AirCraftType { get; set; }
[XmlElement(ElementName = "ETicket")]
public string ETicket { get; set; }
[XmlElement(ElementName = "NonStop")]
public string NonStop { get; set; }
[XmlElement(ElementName = "DepTer")]
public string DepTer { get; set; }
[XmlElement(ElementName = "ArrTer")]
public string ArrTer { get; set; }
[XmlElement(ElementName = "AdtFareBasis")]
public string AdtFareBasis { get; set; }
[XmlElement(ElementName = "ChdFareBasis")]
public string ChdFareBasis { get; set; }
[XmlElement(ElementName = "InfFareBasis")]
public string InfFareBasis { get; set; }
}
[XmlRoot(ElementName = "RecommendedSegment")]
public class RecommendedSegment
{
[XmlElement(ElementName = "Duration")]
public string Duration { get; set; }
[XmlElement(ElementName = "FareBasis")]
public string FareBasis { get; set; }
[XmlElement(ElementName = "FlightSegment")]
public List<FlightSegment> FlightSegment { get; set; }
[XmlElement(ElementName = "DepAirport")]
public string DepAirport { get; set; }
[XmlElement(ElementName = "DepCity")]
public string DepCity { get; set; }
[XmlElement(ElementName = "DepCountry")]
public string DepCountry { get; set; }
[XmlElement(ElementName = "DepZone")]
public string DepZone { get; set; }
[XmlElement(ElementName = "ArrAirport")]
public string ArrAirport { get; set; }
[XmlElement(ElementName = "ArrCity")]
public string ArrCity { get; set; }
[XmlElement(ElementName = "ArrCountry")]
public string ArrCountry { get; set; }
[XmlElement(ElementName = "ArrZone")]
public string ArrZone { get; set; }
}
[XmlRoot(ElementName = "Availability")]
public class Availability
{
[XmlElement(ElementName = "RecommendedSegment")]
public RecommendedSegment RecommendedSegment { get; set; }
}
码….
try
{
Availability deserializedXML = new Availability();
// Deserialize to object
XmlSerializer serializer = new XmlSerializer(typeof(Availability));
using (FileStream stream = File.OpenRead(@"xml.xml"))
{
deserializedXML = (Availability)serializer.Deserialize(stream);
} // Put a break-point here, then mouse-over deserializedXML
}
catch (Exception)
{
throw;
}
将您的XML保存到与.EXE相同的文件夹中的文件(xml.xml)….希望能有所帮助.
