我有一个字符串xml，我想把它转换成C#类，我该怎么做？

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

// 定义与XML结构相匹配的C#类
[XmlRoot("Root")]
public class MyClass
{
    [XmlElement("Name")]
    public string Name { get; set; }

    [XmlElement("Age")]
    public int Age { get; set; }
}

public class Program
{
    public static void Main()
    {
        string xmlString = "<Root><Name>John</Name><Age>25</Age></Root>";

        // 将XML字符串转换为C#对象
        XmlSerializer serializer = new XmlSerializer(typeof(MyClass));
        using (StringReader reader = new StringReader(xmlString))
        {
            MyClass obj = (MyClass)serializer.Deserialize(reader);
            Console.WriteLine("Name: " + obj.Name);
            Console.WriteLine("Age: " + obj.Age);
        }

        // 将C#对象转换为XML字符串
        MyClass obj2 = new MyClass { Name = "Alice", Age = 30 };
        using (StringWriter writer = new StringWriter())
        {
            serializer.Serialize(writer, obj2);
            string result = writer.ToString();
            Console.WriteLine("XML: " + result);
        }
    }
}
