[英]C# Xml Deserialize collection with nested collection, nested collection is null
我正在使用第三方 API。 我正在尝试将 XML 字符串反序列化为 C# 复杂类。 这个 xml 字符串包含一个带有嵌套数组的数组。 我成功序列化到外部列表(“描述”),但嵌套列表是 null(“项目”)。 我不确定问题是什么。
<mlsdata mlsboardid="abcdefg" mlslistingid="23232323">
<description>
<group name="Address">
<item displayname="Address" displayvalue="123 W Apple Ave" standardname="ad_street_address" />
<item displayname="Address Direction" displayvalue="W" standardname="ad_street_direction" />
...
</group>
<group name="Agent/Office">
<item displayname="Agent First Name" displayvalue="John" standardname="ag_name_first" />
<item displayname="Agent Last Name" displayvalue="Dor" standardname="ag_name_last" />
...
</group>
...
</description>
</mlsdata>
C# Class 对象:
[Serializable]
[XmlRoot("item")]
public class Item
{
[XmlAttribute("displayname")]
public string displayname { get; set; }
[XmlAttribute("displayvalue")]
public string displayvalue { get; set; }
[XmlAttribute("standardname")]
public string standardname { get; set; }
}
[Serializable()]
[XmlRoot("group")]
public class Group
{
[XmlAttribute]
public string name { get; set; }
[XmlArray("group")]
[XmlArrayItem("item")]
public List<Item> item { get; set; } // this is null
}
[Serializable]
[XmlRoot("mlsdata")]
public class MLSData
{
[XmlAttribute]
public string mlsboardid { get; set; }
[XmlAttribute]
public string mlslistingid { get; set; }
[XmlAttribute]
public string mlsExternalId { get; set; }
[XmlArray("description")]
[XmlArrayItem("group")]
public List<Group> description { get; set; } = new List<Group>();
}
尝试以下操作:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Xml;
using System.Xml.Serialization;
namespace ConsoleApplication11
{
class Program
{
const string FILENAME = @"c:\temp\test.xml";
static void Main(string[] args)
{
XmlReader reader = XmlReader.Create(FILENAME);
XmlSerializer serializer = new XmlSerializer(typeof(Bookstore));
Bookstore store = (Bookstore)serializer.Deserialize(reader);
}
}
[XmlRoot("bookstore")]
public class Bookstore
{
[XmlElement("book")]
public Book[] book { get; set; }
}
public class Book
{
[XmlAttribute]
public string genre { get; set; }
[XmlAttribute]
public DateTime publicationdate { get; set; }
[XmlAttribute]
public string ISBN { get; set; }
public decimal price { get; set; }
public string title { get; set; }
public Author author { get; set; }
}
public class Author
{
[XmlElement("first-name")]
public string firstname { get; set; }
[XmlElement("last-name")]
public string lastname { get; set; }
}
}
