如何反序列化 XML 内容中的字符串？

Question

我有一个这样的 XML：

<XmlSports CreateDate="2022-12-04T17:47:53.5569879Z">
 <Sport Name="eSports" ID="2357">
  <Event Name="NBA2K, NBA Blitz League" ID="66838" IsLive="false" CategoryID="9357">
   <Match Name="LA Clippers (THA KID) Esports - Milwaukee Bucks (SHARPSHOOTER)" ID="2711992" StartDate="2022-12-04T17:36:00" MatchType="Live">
    <Bet Name="Money Line" ID="43859970" IsLive="true">
     <Odd Name="1" ID="297613016" Value="2.26"/>
     <Odd Name="2" ID="297613021" Value="1.58"/>
    </Bet>
    <Bet Name="Spread" ID="43859969" IsLive="true">
     <Odd Name="1" ID="297614398" Value="1.83" SpecialBetValue="2.5"/>
     <Odd Name="2" ID="297614399" Value="1.90" SpecialBetValue="2.5"/>
    </Bet>
    <Bet Name="Total" ID="43859971" IsLive="true">
     <Odd Name="Over" ID="297613741" Value="1.86" SpecialBetValue="140.5"/>
     <Odd Name="Under" ID="297613740" Value="1.86" SpecialBetValue="140.5"/>
    </Bet>
   </Match>
  </Event>
  <Event Name="FIFA, GT League" ID="62647" IsLive="false" CategoryID="8212">
   .
   . **and so on, the content is too long to post it here** 
   .
 </Sport>
</XmlSports> 

目标是将其反序列化为 C# 个类。

我的课程是这样的：

   using System.Xml.Serialization;

   namespace BettingDataAPI.Models
   {
    [Serializable, XmlRoot("Sport")] 
    public class Sport
    {
    [XmlElement("ID")]
    public int ID { get; set; }

    [XmlElement("Name")]
    public string Name { get; set; }

    [XmlElement("Event")] 
    public List<Event> Events { get; set; }

    }
   }

还：

using System.Xml.Serialization;

namespace BettingDataAPI.Models
{
[XmlType("Event")] 
public class Event
{
    [XmlElement("ID")]
    public int ID { get; set; }

    [XmlElement("Name")]
    public string Name { get; set; }

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


    [XmlElement("IsLive")]
    public bool IsLive { get; set; }

    [XmlElement("Match")]
    public List<Match> Matches { get; set; }

 }
}

我也有课程： Odd ， Match和Bet

这是我的代码：

private static async Task<Sport> DeserializeXMLToObject()
    {
        private static readonly string xmlUrl = @"*here is the url*";
        XmlSerializer ser = new XmlSerializer(typeof(Sport));
        //WebClient client = new WebClient();

        HttpClient client = new HttpClient();
        HttpResponseMessage response = client.GetAsync(xmlUrl).Result;
        string xml = "";  

        if (response.IsSuccessStatusCode)
        {
            xml = response.Content.ReadAsStringAsync().Result; 
        }

        Sport sport = new Sport(); 

        using(TextReader reader = new StringReader(xml))
        {
            sport = (Sport)ser.Deserialize(reader); 
        }

        return sport; 
     }

但在这条线上

sport = (Sport)ser.Deserialize(reader);

它给了我以下错误：

InnerException = {"<XmlSports xmlns=''> was not expected."}

我认为这是因为我已经创建了一个 class XmlSports但我删除了它，因为当我使用 Entity Framework 运行代码优先迁移时，它说有一个错误，因为它无法为表 XmlSports 创建主键，所以我删除了这个 class 并将Sport class 改为根 class。

我试图从这个 883812976388 创建一个 xsd 文件（我创建了一个 test.xml 文件并复制并粘贴了 url 中的内容）但它没有发生，因为它说：处理'test.xml'时出错。

我对 xml 内容以及一般的序列化和反序列化没有经验，所以我很难理解问题出在哪里以及如何修复它。

任何建议将不胜感激！

谢谢！
