Десериализовать файл XML в С#

IDE: Microsoft Visual Studio 2010 Язык: C#, XML

Я пытаюсь десериализовать файл XML в объект, но это выдает ошибку в документе XML (5,4). Есть предложения?

Вот код, который я пробовал...

   public void ReadXMLtblFieldingDetails(string xmlFileXDetails)
        {

            XmlSerializer serializer = new XmlSerializer(typeof(tblXDetails));
            TextReader reader = new StreamReader(xmlXDetails);
            object obj = serializer.Deserialize(reader);
            tblXDetails XmlData = (tblXDetails)obj;
            BusinessObjectManager.Add(XmlData); 

        }

И это XML-документ, который я хочу десериализовать...

<?xml version="1.0"?>
<tblXDetails xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

  <fielder8_y_axis>0</fielder8_y_axis>
  <fielder9_x_axis>0</fielder9_x_axis>
  <fielder9_y_axis>0</fielder9_y_axis>
</tblxDetails>
