How to deserialzie List of KeyValuePair


My Class implements IXmlSerializable and has a property like this:

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

I have an XML Document and have to fill the list with entrys in

public void ReadXml(XmlReader reader)
{
}

My XML-Document looks like this:

<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>

How can i accomplish this?


Solution

  • You can utilize little bit of 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();
    
    }
