C# .net xml sérialisation récupération de valeur de tableau d'éléments xml

Question

J'ai l'exemple xml suivant et j'essaye de désérialiser le xml pour obtenir la valeur du tableau d'éléments xml (l'élément "READING"), pour obtenir le " 22,9 "valeur ci-dessous (c'est difficile à expliquer).

Je peux obtenir toutes les autres valeurs en utilisant XmlSerializer.

Exemple xml:

<LIVE deviceid="1394602" utc="18-Oct-2016 01:22:28" local="18-Oct-2016 12:22:28"> 
     <READINGS type="full" probecount="1" portcount="2" discovery="2"> 
      <READING parameter="Temperature" shortparameter="Temp" unit="°C" channel="1" probeid="3" state="OK" probename="EC202" sensor="0">22.9</READING> 
      <READING parameter="Ozone" shortparameter="O3" unit="ppm" channel="0" probeid="3" state="OK" probename="EC202" sensor="72">5</READING> 
     </READINGS> 
</LIVE> 

ce que je pourrais s'il vous plaît obtenir de l'aide pour cela?

Merci

      </READING> 
     </READINGS>

      var serializer = new XmlSerializer(typeof(LIVE)); 
      using(var reader = new StringReader(xml)) 
      { 
       var live = (LIVE)serializer.Deserialize(reader); 
       var output = default(double); 
       var text = Regex.Match(live.READINGS.READING.Text, @"\d+(\.\d+)?").Value; 
       if (double.TryParse(text, out output)) 
       { 
        Console.WriteLine(output);
