如何取消KeyValuePair的列表

Question

My class实现了IXmlSerializable，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，必须用中的条目填写列表

public void ReadXml(XmlReader reader)
{
}

我的XML文档如下所示：

<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>8</Key>
  </KeyValuePairThatSerializesProperlyOfInt32Boolean>
</Object>

我怎样才能做到这一点？

Answer 1

您可以利用一点点LINQ到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();
}
