InvalidOperationException異常反序列化的Atom XML

Question

我使用此C＃代碼讀取XML的RSS饋送和反序列化對一個模型：

List<RssFeedModel> rssFeedItems = new List<RssFeedModel>(); 
var url = @"http://mimijumi-dev.myshopify.com/blogs/news.atom"; 
string result; 
using (var httpClient = new HttpClient()) 
{ 
    var request = new HttpRequestMessage(HttpMethod.Get, url); 
    var response = await httpClient.SendAsync(request); 
    result = response.Content.ReadAsStringAsync().Result; 
} 
XmlDocument xdoc = new XmlDocument(); 
xdoc.LoadXml(result.ToString()); 
XmlNodeReader xreader = new XmlNodeReader(xdoc); 
XmlSerializer deserializer = new XmlSerializer(typeof(List<RssFeedModel>)); 
rssFeedItems = (List<RssFeedModel>)deserializer.Deserialize(xreader); 

這裏的型號代碼：

[XmlRoot("feed", Namespace = "http://www.w3.org/2005/Atom")] 
public class RssFeedModel 
{ 
    [XmlElement("title")] 
    public string Title { get; set; } 

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

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

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

    [XmlElement("published")] 
    public DateTime PublishDate { get; set; } 

} 

這引發以下例外：

InvalidOperationException: <feed xmlns='http://www.w3.org/2005/Atom'> was not expected. 
Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderList1.Read3_ArrayOfRssFeedModel() 

這條線：

rssFeedItems = (List<RssFeedModel>)deserializer.Deserialize(xreader); 

我按照這個StackOverflow文章中的說明來嘗試修復它：https://stackoverflow.com/a/1232328/177416但它仍然炸燬。

UPDATE：這裏是它試圖反序列化XML：

試試這個。你有一個字符串鏈接，它需要是一個單獨的類。還添加了列表<>對象和屬性，以便您可以看到如何正確反序列化XML的示例。

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

 
namespace ConsoleApplication1 
 
{ 
 
    class Program 
 
    { 
 
     const string FILENAME = @"c:\temp\test.xml"; 
 
     static void Main(string[] args) 
 
     { 
 
      XmlSerializer xs = new XmlSerializer(typeof(RssFeedModel)); 
 
      XmlTextReader reader = new XmlTextReader(FILENAME); 
 
      RssFeedModel rssFeedModel = (RssFeedModel)xs.Deserialize(reader); 
 

 
     } 
 
    } 
 
} 
 
[XmlRoot("feed", Namespace = "http://www.w3.org/2005/Atom")] 
 
public class RssFeedModel 
 
{ 
 
    [XmlElement("title")] 
 
    public string Title { get; set; } 
 

 
    [XmlElement("link")] 
 
    public List<Link> link { get; set; } 
 

 
    [XmlElement("entry")] 
 
    public List<Entry> entry { get; set; } 
 
} 
 
[XmlRoot("link")] 
 
public class Link 
 
{ 
 
    [XmlAttribute("rel")] 
 
    public string rel { get; set; } 
 
    [XmlAttribute("type")] 
 
    public string type { get; set; } 
 
} 
 
[XmlRoot("entry")] 
 
public class Entry 
 
{ 
 
    [XmlElement("id")] 
 
    public string Id { get; set; } 
 

 
    [XmlElement("published")] 
 
    public DateTime PublishDate { get; set; } 
 

 
    [XmlElement("content")] 
 
    public Content content { get; set; } 
 
} 
 
[XmlRoot("content")] 
 
public class Content 
 
{ 
 
    [XmlAttribute("type")] 
 
    public string type { get; set; } 
 
    [XmlText] 
 
    public string text { get; set; } 
 
}
