Unable to deserialize XML

I have a fixed, valid XML document. I am trying to deserialize it to get a hierarchy of objects. However, an exception is thrown.

This is my XML document:

<ROWSET>
   <ROW>
      <LOT>LOT1234</LOT>
      <DATE_TRANS>2012-05-20</DATE_TRANS>
      <NUMERO_AA227>AA227_001</NUMERO_AA227>
      <NUMERO_ETUI>ETUI_001</NUMERO_ETUI>   
      <IDENTITE_BOITE_1>Boite1_1</IDENTITE_BOITE_1>
      <IDENTITE_BOITE_2>Boite1_2</IDENTITE_BOITE_2>
      <IDENTITE_BOITE_3>Boite1_3</IDENTITE_BOITE_3>
      <IDENTITE_BOITE_4>Boite1_5</IDENTITE_BOITE_4>
      <IDENTITE_BOITE_5>Boite1_5</IDENTITE_BOITE_5>
   </ROW>
   <ROW>
      <LOT>LOT5678</LOT>
      <DATE_TRANS>2012-05-20</DATE_TRANS>
      <NUMERO_AA227>AA227_001</NUMERO_AA227>
      <NUMERO_ETUI>ETUI_001</NUMERO_ETUI>   
      <IDENTITE_BOITE_1>Boite1_1</IDENTITE_BOITE_1>
      <IDENTITE_BOITE_2>Boite1_2</IDENTITE_BOITE_2>
      <IDENTITE_BOITE_3>Boite1_3</IDENTITE_BOITE_3>
      <IDENTITE_BOITE_4>Boite1_5</IDENTITE_BOITE_4>
      <IDENTITE_BOITE_5>Boite1_5</IDENTITE_BOITE_5>
   </ROW>
</ROWSET>

And this is my object model:

[Serializable]
[System.Xml.Serialization.XmlRoot("DTOFournitureListeImporter")]
public class DTOFournitureListeImporter
{
   [XmlArray("ROWSET")]
   [XmlArrayItem("ROW", typeof(DTOFournitureImporter))]
   public DTOFournitureImporter[] dtoFournitureImporter { get; set; }
}

[Serializable]
public class DTOFournitureImporter
{
   [System.Xml.Serialization.XmlElement("lot")]
   public string lot { get; set; }

   [System.Xml.Serialization.XmlElement("date_trans")]
   public DateTime date_trans { get; set; }

   [System.Xml.Serialization.XmlElement("numero_aa227")]
   public string numero_aa227 { get; set; }

   [System.Xml.Serialization.XmlElement("numero_etui")]
   public string numero_etui { get; set; }

   [System.Xml.Serialization.XmlElement("identite_boite_1")]
   public string identite_boite_1 { get; set; }

   [System.Xml.Serialization.XmlElement("identite_boite_2")]
   public string identite_boite_2 { get; set; }

   [System.Xml.Serialization.XmlElement("identite_boite_3")]
   public string identite_boite_3 { get; set; }

   [System.Xml.Serialization.XmlElement("identite_boite_4")]
   public string identite_boite_4 { get; set; }

   [System.Xml.Serialization.XmlElement("identite_boite_5")]
   public string identite_boite_5 { get; set; }
}

How do I deserialize:

XmlSerializer serializer = new XmlSerializer(typeof(DTOFournitureListeImporter));
TextReader textReader = new StreamReader(model.cheminFichierXML);
DTOFournitureListeImporter dTOFournitureListeImporter = (DTOFournitureListeImporter)serializer.Deserialize(textReader);
textReader.Close();

And the error:

There is an error in the XML document (2, 2). - System.InvalidOperationException: not expected. Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderDTOFournitureListeImporter.Read4_DTOFournitureListeImporter ()
