如何在ItemName中序列化带有数字的XML集合？

public class Item
{
    public int Number { get; set; }
    public string Name { get; set; }
}

List<Item> items = new List<Item>
{
    new Item { Number = 1, Name = "Item 1" },
    new Item { Number = 2, Name = "Item 2" },
    new Item { Number = 3, Name = "Item 3" }
};

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

XmlSerializer serializer = new XmlSerializer(typeof(List<Item>));
StringWriter stringWriter = new StringWriter();
serializer.Serialize(stringWriter, items);
string xmlString = stringWriter.ToString();
