C#: deserialize xml

Question

I can't deserialize the xml-File below: how to do?

some infos:

• object Machine has one or several "BOX" and "Component"
• object Box has several "Component"
• object Component can contain several "Subcomponent"
• each object contains GeoVar with a plenty of inner elements beginning with D such as D1, D3 and so on. It varies form an object to another.
• each IfcProp has descriptive inner element.

XML-File:

You are missing root element class i.e. Configurator

[Serializable, XmlRoot(ElementName = "Configurator")]
public class Configurator
{
    [XmlElement(ElementName = "Machine")]
    public Machine Machine { get; set; }
}

And while de-serializing use Configurator instead of Machine.

XmlSerializer serializer = new XmlSerializer(typeof(Configurator));
using (TextReader reader = new StringReader(System.IO.File.ReadAllText(file)))
{
    Configurator result = (Configurator)serializer.Deserialize(reader);
    MachineList.Add(result.Machine);
}
