如何使用 C# 映射反序列化 XML 文档

Question

我是 C# 编程的新手，我陷入了如何反序列化这个 XML 文档，我看过这个教程 How to Deserialize XML document，它很有帮助，但是你可以看到我的 XML 包含更多信息，而且他更复杂：

<?xml version="1.0" encoding="utf-8"?>
<Classrooms>
    <Classroom name="ClassroomA">
        <Students name = "John"/>
        <Students name = "Bryan"/>
        <Students name = "Eva"/>
    </Classroom>
    <Classroom name="ClassroomB">
        <Students name = "Harry"/>
        <Students name = "Emma"/>
        <Students name = "Joe"/>
    </Classroom>
    <Classroom name="ClassroomC">
        <Students name = "Lionnel"/>
        <Students name = "Rio"/>
        <Students name = "Eva"/>
    </Classroom>
</Classrooms>

我的主要目标是从我的 XML 文件创建教室地图：

示例：字典教室，

键 1：教室 A，价值观：John、Bryan、Eva

关键 2：教室 B，价值观：Harry、Emma、Joe

关键 3：classicC，价值观：Lionnel、Rio、Eva

感谢您的帮助

尝试以下：

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

namespace ConsoleApplication178
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlReader reader = XmlReader.Create(FILENAME);
            XmlSerializer serializer = new XmlSerializer(typeof(Classrooms));
            Classrooms classrooms = (Classrooms)serializer.Deserialize(reader);
            reader.Close();
            //using xml linq
            XDocument doc = XDocument.Load(FILENAME);
            Dictionary<string, List<string>> dict = doc.Descendants("Classroom")
                .GroupBy(x => (string)x.Attribute("name"), y => y)
                .ToDictionary(x => x.Key, y => y.Elements("Students").Select(x => (string)x.Attribute("name")).ToList());
        }
    }
    public class Classrooms
    {
        [XmlElement()]
        public List<Classroom> Classroom { get; set; }
    }
    public class Classroom
    {
        [XmlAttribute]
        public string name { get; set; }

        [XmlElement()]
        public List<Students> Students { get; set; }

    }
    public class Students
    {
        [XmlAttribute]
        public string name { get; set; }
    }
}
