**
Usage :
Serialize : TAObjectSerializer.Serialize(myClassInstance); //this returns as XmlDocument
Deserialize : TAObjectSerializer.Deserialize(myXmlDocument); //this returns as object instance
**
diese Klasse alle READ_WRITE Eigenschaften wenn Eigenschaft serialisiert werden nicht markiert durch NonSerializedAttribute Attribut
Viel Glück!
