C# 如何将List集合序列化为xml

<strong>public class Person</strong>
{
    <strong>public string Name { get; set; }</strong>
    <strong>public int Age { get; set; }</strong>
}

<strong>using System;
using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;</strong>

var people = new List<Person>
{
    new Person { Name = "张三", Age = 30 },
    new Person { Name = "李四", Age = 25 }
};

var serializer = new XmlSerializer(typeof(List<Person>));
using (var writer = new StringWriter())
{
    serializer.Serialize(writer, people);
    string xml = writer.ToString();
    Console.WriteLine(xml);
}

<strong>[XmlRoot("People")]
public class Person</strong>
{
    <strong>[XmlElement("PersonName")]
    public string Name { get; set; }</strong>

    <strong>[XmlElement("PersonAge")]
    public int Age { get; set; }</strong>
}

using (var file = new StreamWriter("people.xml"))
{
    serializer.Serialize(file, people);
}
