无法使用ReadAsAsync<T>反序列化XML响应中的列表

using System;
using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;

// 创建适当的实体类来表示XML响应中的项
[XmlRoot("Item")]
public class Item
{
    [XmlElement("Name")]
    public string Name { get; set; }
    
    [XmlElement("Value")]
    public int Value { get; set; }
}

public class Program
{
    public static void Main(string[] args)
    {
        string xmlResponse = "<Response><Items><Item><Name>Item 1</Name><Value>10</Value></Item><Item><Name>Item 2</Name><Value>20</Value></Item></Items></Response>";
        
        // 使用XmlSerializer进行反序列化
        XmlSerializer serializer = new XmlSerializer(typeof(List<Item>), new XmlRootAttribute("Items"));
        
        using (StringReader reader = new StringReader(xmlResponse))
        {
            List<Item> items = (List<Item>)serializer.Deserialize(reader);
            
            // 处理数据
            foreach (Item item in items)
            {
                Console.WriteLine("Name: " + item.Name);
                Console.WriteLine("Value: " + item.Value);
            }
        }
    }
