是否可以将 XML 反序列化为 List<T>? [英] Is it possible to deserialize XML into List&lt;T&gt;?

问题描述

给定以下 XML:

<?xml version="1.0"?>
<user_list>
   <user>
      <id>1</id>
      <name>Joe</name>
   </user>
   <user>
      <id>2</id>
      <name>John</name>
   </user>
</user_list>

还有以下类:

public class User {
   [XmlElement("id")]
   public Int32 Id { get; set; }

   [XmlElement("name")]
   public String Name { get; set; }
}

是否可以使用 XmlSerializer 将 xml 反序列化为 List ?如果是这样，我需要使用什么类型的附加属性，或者我需要使用哪些附加参数来构造 XmlSerializer 实例?

Is it possible to use XmlSerializer to deserialize the xml into a List<User> ? If so, what type of additional attributes will I need to use, or what additional parameters do I need to use to construct the XmlSerializer instance?

数组 ( User[] ) 是可以接受的，如果不太可取的话.

An array ( User[] ) would be acceptable, if a bit less preferable.

推荐答案

您可以轻松封装列表:

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

[XmlRoot("user_list")]
public class UserList
{
    public UserList() {Items = new List<User>();}
    [XmlElement("user")]
    public List<User> Items {get;set;}
}
public class User
{
    [XmlElement("id")]
    public Int32 Id { get; set; }

    [XmlElement("name")]
    public String Name { get; set; }
}

static class Program
{
    static void Main()
    {
        XmlSerializer ser= new XmlSerializer(typeof(UserList));
        UserList list = new UserList();
        list.Items.Add(new User { Id = 1, Name = "abc"});
        list.Items.Add(new User { Id = 2, Name = "def"});
        list.Items.Add(new User { Id = 3, Name = "ghi"});
        ser.Serialize(Console.Out, list);
    }
}
