Question

我使用这个C＃代码来读取XML RSS提要并根据模型对其进行反序列化：

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);

这是模型代码：

[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; }

}

这会引发以下异常：

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

这一行：

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

我按照此StackOverflow帖子中的说明尝试修复它：https://stackoverflow.com/a/1232328/177416但它仍然在爆炸。

更新：这是它尝试反序列化的XML：

试试这个。你有链接作为字符串，它需要是一个单独的类。还添加了List＆lt;＆gt;对象和属性，以便您可以看到如何正确反序列化XML的示例。

＆＃13;

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; }
}
