Probleme mit Deserialisieren xml Objektstruktur C#

Question

Ich habe folgende xml:

<Root> 
<ProcessingUnit>Lifestyle</ProcessingUnit> 
<ProcessingData> 
    <ProcessType>Product</ProcessType> 
    <ProcessAction>Create</ProcessAction> 
    <Id>7</Id> 
</ProcessingData> 
</Root> 

und ich habe die folgende Objektstruktur

[XmlRoot("Root")] 
public class XmlRoot 
{ 
    ProcessingUnit ProcessingUnit { get; set; } 
    [XmlElement("ProcessingData")] 
    ProcessingData ProcessingData { get; set; } 
} 

public class ProcessingData 
{ 
    public ProcessType ProcessType { get; set; } 
    public ProcessAction ProcessAction { get; set; } 
    public int Id { get; set; } 
} 

Wenn ich deserialisieren i wie folgt vor:

XmlSerializer _serializer = new XmlSerializer(typeof(XmlRoot)); 
using (var reader = new StringReader(stringtest)) 
{ 
    var tradeData = (XmlRoot)_serializer.Deserialize(reader); 
} 

Deserialisierung zu Enums funktioniert einwandfrei, die processingUnit wird korrekt deserialisiert, aber die Eigenschaft ProcessingData ist null.

Ich habe versucht, mit vielen verschiedenen XML-Attribute zu dekorieren, aber ich kann nicht sehen, warum ich den Nullwert bekomme.

EDIT: Die stringtest Variable hat den Wert:

var stringtest = 
      "<Root><ProcessingUnit>Lifestyle</ProcessingUnit><ProcessingData><ProcessType>Product</ProcessType><ProcessAction>Create</ProcessAction><Id>7</Id></ProcessingData></Root>"; 

Die Aufzählungen wie folgt aussieht:

public enum ProcessType 
{ 
    [XmlEnum(Name = "Product")] 
    Product, 

    [XmlEnum(Name = "Category")] 
    Category, 
} 

public enum ProcessAction 
{ 
    [XmlEnum(Name = "Create")] 
    Create, 

    [XmlEnum(Name = "Delete")] 
    Delete, 

    [XmlEnum(Name = "Update")] 
    Update, 
} 

public enum ProcessingUnit 
{ 
    [XmlEnum(Name = "LifeStyle")] 
    LifeStyle 
}

Eigenschaften öffentlich sein müssen

     private void button1_Click(object sender, EventArgs e) 
     { 
      string stringtest = "<Root>" + 
       "<ProcessingUnit>Lifestyle</ProcessingUnit>" +
