使用 XMLdocument 中的 C# 将 XML 反序列化为 Entitylist

Question

将以下具有多个事件节点的 XML 文件引用到父事件标记中

<events>
<event eventid="ahjy67kl" sessionid="1">
<eventtitle>
<![CDATA[ phoneEventchad_1 ]]>
</eventtitle>
<eventabstract/>
<timezone>IND</timezone>

实体类

public class events
{
    private Event _event;

    [XmlElement(ElementName = "event")] 
    public Event Event
    {
        get
        {
            return this._event;
        }
        set
        {
            this._event = value;
        }
    }
}

[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public class Event
{
    public string eventid { get; set; }
    public string sessionid { get; set; }
    public string eventTitle { get; set; }      
    public DateTime archivestartdate { get; set; }
    public DateTime archiveenddate { get; set; }
    public string eventabstract { get; set; }
    public DateTime eventtimedate { get; set; }
    public string eventprofile { get; set; }
    public string registrantcount { get; set; }
    public string sponsor { get; set; }
    public string keywords { get; set; }
    public string eventstdfield1 { get; set; }
    public string eventstdfield2 { get; set; }
    public string eventstdfield3 { get; set; }
    public string eventstdfield4 { get; set; }
    public string eventstdfield5 { get; set; }
    public attendancestats attendancestats { get; set; }
    public registrationstats registrationstats { get; set; }

    public Event()
    { }
}

public class attendancestats
{
    public string attendedcount { get; set; }
    public string noshowcount { get; set; }
    public string attendedlivecount { get; set; }
    public string attendedarchivecount { get; set; }       

}
public class registrationstats
{
    public string registrantcount { get; set; } 
}

我使用下面的代码将提到的 XML 反序列化到上面的实体类中

pDoc是上面xml填充的XMLdocument的对象

System.Xml.Serialization.XmlRootAttribute xRoot = new System.Xml.Serialization.XmlRootAttribute(); xRoot.ElementName = "事件"; xRoot.IsNullable = true;

        System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(List<events>),xRoot);
        XDocument Doc = new XDocument();
        Doc = XDocument.Parse(pDoc.OuterXml);
        //System.Xml.XmlReader reader = Doc.CreateReader();
        XmlReader reader = XmlReader.Create(new System.IO.StringReader(Doc.ToString()));
        List<Event> result = (List<Event>)serializer.Deserialize(reader);
        reader.Close();

在上面的代码阅读器对象中，由于 List 的哪个结果对象抛出异常，因此为 null。

我想要事件列表。

请帮我实现事件列表。如果需要提供更多详细信息，请告诉我。

我真的不明白这是如何工作的。您的 Event 类似乎只有一个事件，XML 文件包含许多事件。试试这个：

[Serializable]
[XmlRoot(ElementName = "events")]
public class Events {

   public Events()
   {
    EventList = new List<Event>();
   }
   [XmlElement(ElementName="event")]
   List<Event> EventList {get; set;}
}

[Serializable]
public class Event {
  [XmlAttribute("eventid")
  public string eventid {get; set;}
    .......

 [XmlElement(ElementName="timezone")]
  public string timezone {get; set;}
}

很明显，您需要对每个可用属性都这样做。现在，反序列化：

        string input = System.IO.File.ReadAllText(PATH_TO_YOUR_XML_FILE); //this can be replaced with any func giving string
        XmlSerializer xmlSerializer = new XmlSerializer(typeof(Events));
        var doc = XDocument.Parse(input);
        using (var reader = doc.Root.CreateReader())
        {
            return (Events)xmlSerializer.Deserialize(reader);
        }

好的，这将产生Events类，在EventList中有List。希望这会有所帮助。
