数组的 C# XML 反序列化

Question

我有一个关于反序列化数组的问题。因为数组元素可以有多种类型。你可以看到这个例子:

<?xml version="1.0" encoding="UTF-8"?><export xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://zakupki.gov.ru/oos/export/1" xmlns:oos="http://zakupki.gov.ru/oos/types/1">
<notificationZK>
    ... item 1 data
</notificationZK>
<notificationZK>
    ... item 2 data
</notificationZK>
<notificationFF>
    ... item 3 data
</notificationFF>
</export>

所有元素都扩展notificationType

   [System.Xml.Serialization.XmlIncludeAttribute(typeof(notificationSZType))]
    [System.Xml.Serialization.XmlIncludeAttribute(typeof(notificationPOType))]
    [System.Xml.Serialization.XmlIncludeAttribute(typeof(notificationZKType))]
    [System.Xml.Serialization.XmlIncludeAttribute(typeof(notificationEFType))]
    [System.Xml.Serialization.XmlIncludeAttribute(typeof(notificationOKType))]
    public partial class notificationType
    {
...

所以问题是如何从我的 XML 文件中获取 notificationType 元素的集合？我想我不能做类似的事情

[Serializable()]
[System.Xml.Serialization.XmlRoot("export")]
public class NotificationCollection
{
    [XmlArray("")] // ???? what I need write here?
    [XmlArrayItem("", typeof(notificationType))] // ??? and here?
    public notificationType[] notification { get; set; }
}

问候!

已添加----------------

所以。我做这个:

[Serializable()]
[System.Xml.Serialization.XmlRoot("export")]
public class NotificationCollection
{
    [XmlElement("notificationSZType", Type = typeof(notificationSZType))]
    [XmlElement("notificationPOType", Type = typeof(notificationPOType))]
    [XmlElement("notificationZKType", Type = typeof(notificationZKType))]
    [XmlElement("notificationEFType", Type = typeof(notificationEFType))]
    [XmlElement("notificationOKType", Type = typeof(notificationOKType))]
    public notificationType[] notification { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        NotificationCollection collection = null;
        string path = @"E:\notification.xml";
        XmlSerializer serializer = new XmlSerializer(typeof(notificationType));
        StreamReader reader = new StreamReader(path);
        collection = (NotificationCollection) serializer.Deserialize(reader);
        reader.Close();

    }
}

但是在 serializer.Deserialize(reader);

时未处理 System.InvalidOperationException

Message=<export xmlns='http://zakupki.gov.ru/oos/export/1'> not expected.

我做错了什么？

如何将类型声明移动到集合中？

[XmlRoot("export")]
public class NotificationCollection
{

  [XmlElement("notificationZK", typeof(NotificationTypeZK))]
  [XmlElement("notificationFF", typeof(NotificationTypeFF))]
  public List<NotificationType> Notifications { get; set; }

}

public class NotificationType
{

}

public class NotificationTypeZK : NotificationType { }

public class NotificationTypeFF : NotificationType { }

static void Main(string[] args)
{
  var data = @"<export><notificationZK /><notificationZK /><notificationFF /></export>";

  var serializer = new XmlSerializer(typeof(NotificationCollection));

  using (var reader = new StringReader(data))
  {
    var notifications = serializer.Deserialize(reader);
  }
}
