Why does deserialization fail?

XML:

Code:

---

<?xml version="1.0" encoding="utf-8" ?>
<TTTTModel>
    <TTTTClass>
        <TTTTType>Deployment</TTTTType>
        <TTTTDate>2009-09-30T00:00:00-07:00</TTTTDate>
    </TTTTClass>
    <TTTTClass>
        <TTTTType>Deployment</TTTTType>
        <TTTTDate>2009-09-20T00:00:00-07:00</TTTTDate>
    </TTTTClass>
    <TTTTClass>
        <TTTTType>Copy</TTTTType>
        <TTTTDate>2009-02-23T00:00:00-07:00</TTTTDate>
    </TTTTClass>
</TTTTModel>

---

The code:

Code:

---

[Serializable]
    public class ActionClass
    {
        [XmlElement(Form=XmlSchemaForm.Unqualified)]
        public string ActionType { get; set; }
        [XmlElement(Form = XmlSchemaForm.Unqualified)]
        public DateTime ActionDate { get; set; }
    }




    public class ActionModel : List<ActionClass>
    {
        public ActionModel()
        {
            XmlSerializer xs = new XmlSerializer(typeof(ActionModel), "");

            using (Stream ms = new FileStream("Demo.xml", FileMode.Open, FileAccess.Read))
            {
                object inp = xs.Deserialize(ms);
                this.AddRange((ActionModel)inp);
            }
        }
    }

---

Why I get exception on object inp = xs.Deserialize(ms)?

Quote:

---

<ActionModel xmlns=''> was not expected.

---

How to fix it?

Code:

---

///<summary>
/// Request adapter
///</summary>
[XmlType( AnonymousType = true )]
[XmlRoot( ElementName = "TTTTModel", Namespace = "", IsNullable = false )]
publicclassActionModel
{
  ///<remarks/>
  [XmlElement( "TTTTClass" )]
  publicActionClass [ ] Actions
  {
    get { return _actionList.ToArray( ); }
    set
    {
      if ( null == _actionList )
      {
        _actionList = newList<ActionClass>( );
      }

      if ( value != null )
      {
        _actionList.AddRange( value );
      }
    }
  }


  privateList<ActionClass> _actionList = newList<ActionClass>( );
}
 
[Serializable( )]
[XmlType( AnonymousType = true )]
publicclassActionClass
{
  [XmlElement( "TTTTType" )]
  publicstring Type { get { return _type; } set { _type = value; } }
 
  [XmlElement( "TTTTDate" )]
  publicstring Date { get { return _date; } set { _date = value; } }


  privatestring _type;
  privatestring _date;
}


classProgram
{
  staticvoid Main( string [ ] args )
  {
    XmlSerializer xs = newXmlSerializer( typeof( ActionModel ), "" );

    using ( Stream ms = newFileStream( "Demo.xml", FileMode.Open, FileAccess.Read ) )
    {
      ActionModel am = ( ActionModel )xs.Deserialize( ms );
    }
  }
}
