使用MemoryStream写出XML

using System;
using System.IO;
using System.Xml.Serialization;

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

public static void Main()
{
    Person person = new Person { Name = "John", Age = 30 };

    XmlSerializer serializer = new XmlSerializer(typeof(Person));
    MemoryStream memoryStream = new MemoryStream();
    serializer.Serialize(memoryStream, person);

    memoryStream.Seek(0, SeekOrigin.Begin);
    StreamReader reader = new StreamReader(memoryStream);
    string xml = reader.ReadToEnd();

    Console.WriteLine(xml);
}
