【问题描述】：

我有以下 XML -

My XML

类结构->

public class AvailabilityResponse
  
    public string property_id  get; set; 
    public List<AvailRoom> rooms  get; set; 
    public Links links  get; set; 
    public int score  get; set; 
    public string Type  get; set; 
    public string Message  get; set; 
    public string status  get; set; 
  
public class AvailRoom
  
    public string id  get; set; 
    public string room_name  get; set; 
    public List<AvailRate> rates  get; set; 
  
[Serializable]
  public class AvailRate
  
    public string id  get; set; 
    public int available_rooms  get; set; 
    public bool refundable  get; set; 
    public bool fenced_deal  get; set; 
    public bool fenced_deal_available  get; set; 
    public bool deposit_required  get; set; 
    public string merchant_of_record  get; set; 
    public List<Amenity> amenities  get; set; 
    public Links links  get; set; 
    //[XmlElement(ElementName = "bed_groups")]
    //public List<BedGroups> bed_groups  get; set; 
    [XmlElement(ElementName = "bed_groups")]
    public List<BedGroup> bed_groups  get; set; 
    public List<CancelPenalty> cancel_penalties  get; set; 
    public Dictionary<string, occupancy_pricing> occupancy_pricing  get; set; 
    public occupancy_pricing Occupancy  get; set; 
  
public class BedGroup
  
    public Links links  get; set; 
    public List<Configuration> configuration  get; set; 
  
[Serializable]
  public class Links
  

    public PaymentOptions payment_options  get; set; 

    public Book book  get; set; 

    public PriceCheck price_check  get; set; 

    public AdditionalRates additional_rates  get; set; 

    public Retrieve retrieve  get; set; 

    public Cancel cancel  get; set; 

    public Change change  get; set; 

    public string method  get; set; 

    public string href  get; set; 

  
[Serializable]
  public class PriceCheck
  
    public string method  get; set; 
    public string href  get; set; 
  

结构的问题是，除了bed_groups，所有其他元素都被绑定了。

我尝试了不同的条件，比如用 Visual Studio 序列化 xml 类，用不同的标签注释它们。但这没有用。

例如。 cancel_penalties 具有类似的结构，但它正确绑定到 c# 类。 bed_groups 没有被绑定。每次它都为空，尽管值存在于 xml 中。

是因为 - <a:item xmlns:a="item" item="37316" type="object"> in bed_groups 和其他标签它只有 - <item type="object"> 吗？

有什么办法可以解决这个问题？

【参考方案1】：

您需要命名空间。下面的代码是您的类的一个子集，并且已经过测试并且可以工作

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication1

    class Program
    
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        
            XmlReader reader = XmlReader.Create(FILENAME);
            XmlSerializer serizlizer = new XmlSerializer(typeof(AvailabilityResponse));
            AvailabilityResponse response = (AvailabilityResponse)serizlizer.Deserialize(reader);
        
    
    public class AvailabilityResponse
    
        [XmlArray("item")]
        [XmlArrayItem("rooms")]
        public List<AvailRoom> rooms  get; set; 
    
    public class AvailRoom
    
        public Item item  get; set; 
    
    public class Item
    
        public string id  get; set; 
        public string room_name  get; set; 
        [XmlArray("rates")]
        [XmlArrayItem("item")]
        public List<AvailRate> rates  get; set; 
    
    [Serializable]
    public class AvailRate
    
        [XmlElement(ElementName = "bed_groups")]
        public List<BedGroup> bed_groups  get; set; 
    
    public class BedGroup
    
        [XmlElement(ElementName = "item", Namespace = "item")]
        public BedGroupItem item  get; set; 
    
    public class BedGroupItem
    
        [XmlElement(Namespace = "")]
        public Links links  get; set; 
        [XmlElement(Namespace = "")]
        public List<Configuration> configuration  get; set; 
    
    public class Links
    
    
    public class Configuration

我试过这个。为什么我的班级结构中的 cancel_penalties 工作正常而不是 bed_groups ？
