如何反序列化KeyValuePair列表

Question

我的类实现 IXmlSerialized 并具有如下属性：

    public List<KeyValuePair<int, bool>> exportList
    {
        get { return _exportList; } 
        set { _exportList = value; }
    }

我有一个 XML 文档，并且必须使用我的 XML 文档中的条目填充列表，

public void ReadXml(XmlReader reader)
{
}

如下所示：

<Object msdata:InstanceType="CYNOX_Datenlogger_Software.Geräte.Slave, CYNOX_Datenlogger_Software, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" Name="Device 4" ID="4" IDParent="3" PrimeAddress="0" SecondaryAdd="10520089" AdditionalInfo="" Locked="False" StandAlone="True" ManuID="ELS" csvPath="" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

    <Key>4</Key>
  </KeyValuePairThatSerializesProperlyOfInt32Boolean>
  <KeyValuePairThatSerializesProperlyOfInt32Boolean xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    <Key>5</Key>
  </KeyValuePairThatSerializesProperlyOfInt32Boolean>
  <KeyValuePairThatSerializesProperlyOfInt32Boolean xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    <Key>6</Key>
  </KeyValuePairThatSerializesProperlyOfInt32Boolean>
  <KeyValuePairThatSerializesProperlyOfInt32Boolean xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

  <KeyValuePairThatSerializesProperlyOfInt32Boolean xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <Value>false</Value>
    <Key>8</Key>
  </KeyValuePairThatSerializesProperlyOfInt32Boolean>
</Object>

我怎样才能完成此操作？

Answer 1

您可以利用一点 LINQ to XML：

public void ReadXml(XmlReader reader)
{
    var document = XDocument.Load(reader);
    this._exportList = document
        .Descendants("KeyValuePairThatSerializesProperlyOfInt32Boolean")
        .Select(e => new KeyValuePair<int, bool>(
            Int32.Parse(e.Element("Key").Value),
            Boolean.Parse(e.Element("Value").Value)
        )).ToList();

}
