[C#] Class serialiseren en deserialiseren

Enkel even een code dump deze keer:

public void Serialize(Configuration c)
{
   XmlSerializer serializer = new XmlSerializer( c.GetType() );
   StreamWriter streamwrite = new StreamWriter("config.xml");

   serializer.Serialize(streamwrite, this);

   streamwrite.Close();

}

public static Configuration Deserialize()
{
   FileInfo file = new FileInfo("config.xml");
   if (file.Exists)
   {
       StreamReader reader = new StreamReader("config.xml");
       XmlSerializer ser = new XmlSerializer(typeof(Configuration));

       Configuration c = (Configuration)ser.Deserialize(reader);

       reader.Close();

       return c;
   }
   else
       return null;
}
