c# 反序列化 XML 嵌套集合

Question

您好，我有一些 XML，我希望使用 XMLSerializer 反序列化为 .NET POCO

xml 看起来像这样:

<?xml version="1.0" encoding="UTF-8"?>
  <message uuid="{2f1e274c-6a53-afea-3047-6dc739539656}">
    <envelope received="a_date" subject="a_name">
      <from>
        <monitor name="Local Folder" user_description="" uuid="{668DC658-97D7-42c8-AE72-ED289DD02355}"/>
      </from>
      <to>
        <account>
          <factory name="a_name"/>
        </account>
      </to>
    </envelope>
    <status>
      <action name="Folder" occured="a_date" type="monitor">
        <session completed="a_date" name="a_name" started="a_date"/>
      </action>
      <action occured="a_date" type="monitor"/>
      <action occured="a_date" type="translate">
        <session completed="a_date" current="a_number" name="a_name" started="a_date" total="a_number" unit="time"/>
        <session completed="a_date" current="a_number" name="a_name" started="a_date" total="a_number" unit="time"/>
      </action>
      <action occured="a_date" type="deliver">
        <session completed="a_date" current="a_number" name="a_name" started="a_date" total="a_number" unit="byte"/>
        <session completed="a_date" name="a_name" started="a_date" unit="byte"/>
        <session completed="a_date" current="a_number" name="a_name" started="a_date" total="a_number" unit="byte"/>
      </action>
      <action occured="a_date" type="complete"/>
    </status>
    <host name="a_name"/>
</message>

在 xml 中，我有一个状态部分，其中包含一组操作，每个操作可能包含一组 session 。

我已经为 XMLSerialiser 创建了类来反序列化 xml:

namespace myNameSpace
{
    [XmlRoot("message")]
    public class message
    {
        [XmlAttribute("uuid")] 
        public string uuid { get; set; }
        [XmlElement("envelope")]
        public envelope envelope { get; set; }
        [XmlArray("status")]
        [XmlArrayItem(typeof(action))]
        public ObservableCollection<action> status { get; set; }
        [XmlElement("host")]
        public host host { get; set; }
    }

    public class envelope
    {
        [XmlAttribute("received")] 
        public string received { get; set; }
        [XmlAttribute("subject")]
        public string subject { get; set; }
        [XmlElement("from")]
        public from from { get; set; }
        [XmlElement("to")]
        public to to { get; set; }
    }

    #region envelope element definitions

    public class from
    {
        [XmlElement("monitor")]
        public monitor monitor { get; set; }

    }

    public class monitor
    {
        [XmlAttribute("name")]
        public string name { get; set; }
        [XmlAttribute("user_description")]
        public string user_description { get; set; }
        [XmlAttribute("uuid")]
        public string uuid { get; set; }

    }

    public class to
    {
        [XmlElementAttribute("account")]
        public account account { get; set; }
    }

    public class account
    {
        [XmlElementAttribute("factory")]
        public factory factory { get; set; }
    }

    public class factory
    {
        [XmlAttribute("name")]
        public string name { get; set; }
    }

    #endregion

    public class action
    {
        [XmlAttribute("name")]
        public string name { get; set; }
        [XmlAttribute("occured")]
        public string occured { get; set; }
        [XmlAttribute("type")]
        public string type { get; set; }
        [XmlArray("action")]
        [XmlArrayItem(typeof(session))]
        public ObservableCollection<session> session { get; set; }
    }

    public class session
    {
        [XmlAttribute("completed")]
        public string completed { get; set; }
        [XmlAttribute("current")]
        public long current { get; set; }
        [XmlAttribute("name")]
        public string name { get; set; }
        [XmlAttribute("started")]
        public string started { get; set; }
        [XmlAttribute("total")]
        public long total { get; set; }
        [XmlAttribute("unit")]
        public string unit { get; set; }
    }

    public class host
    {
        [XmlAttribute("name")]
        public string name { get; set; }
    }
}

大多数情况下，我得到了我想要的对象图，所有值都正确反序列化了，但我找不到让 XMLSerialiser 反序列化操作元素内的 session 集合的方法 - 它们总是空的。

有谁知道我应该如何构建我的 POCO，以便 XMLserialiser 可以创建 session 集合？

最好的问候

约翰。

这是使用 xsd.exe 生成的。希望这会有所帮助。
