c＃反序列化XML嵌套集合

您好我有一些XML希望使用XMLSerializer反序列化到.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，其中包含一系列操作，每个操作可能包含一组会话。

我已经为XMLSerialiser创建了用于反序列化xml的类：

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，我得到了所需的对象图，所有值都正确反序列化，但我找不到让XMLSerialiser在动作元素中反序列化会话集合的方法 - 总是为空。

有谁知道如何构建我的POCO以便XMLserialiser可以创建会话集合？

最好的问候

我相信你的问题是一旦你处于动作级别，就不能将它指定为Xml数组类型。这将是会议。尝试一下，看看它是否有效：

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(typeof(session))]
    public ObservableCollection<session> session { get; set; }
}

首先，session必须继承action。

然后，您可能需要将public ObservableCollection<action> status { get; set; }替换为public List<action> status { get; set; }或public action[] status { get; set; }（如果ObservableCollection被视为XmlSerializable，则不需要。）

最后，您可能需要在[XmlInclude(typeof(session))]类声明中添加action。
