反\\序列化对象列表XML

Question

I have been tried to do deserialize and it doesn't work. Why it happen ? Im tring to deserialize list of object as I serialize list of object. Is it possible ? Im trying something but it doens't the correct way. Thanks on help.

My code :

in the main :

Serialize(lstObservers);

 public void Serialize(List<Observer> list)
        {
           XmlSerializer serializer = new XmlSerializer(typeof(List<Observer>));
            using ( TextWriter writer = new StreamWriter( @"C:\Users\user\Desktop\MapSample\bin\Debug\ListObserver.xml"))
            {
                serializer.Serialize(writer, list);
            }  
        }

   private void DiserializeFunc()
        {
            var myDeserializer = new XmlSerializer(typeof(List<Observer>));
        using (var myFileStream = new FileStream(@"C:\Users\user\Desktop\MapSample\bin\Debug\ListObserver.xml", FileMode.Open))
        {
            listObservers = (List<Observer>)myDeserializer.Deserialize(myFileStream);
        }

        }

the class observer :

    [Serializable()]
    public class Observer : MapObject
    {
        private int ID_Observer { get; set; }
        private double azimuth;
        private double Long;
        private double Lat;
        private double Lenght;
        private bool haveConnection;
        private bool DrawAzimuth;
        private XmlSerializer ser;

        /// <summary>
        /// C'tor
        /// </summary>
        public Observer(int ID_Observer = 0, double azimuth = 0, double Lat = 0, double Long = 0, double Lenght = 0, bool haveConnection = true, bool DrawAzimuth = true)
        {
            this.ID_Observer = ID_Observer;
            this.azimuth = azimuth;
            this.Long = Long;
            this.Lat = Lat;
            this.haveConnection = haveConnection;
            this.DrawAzimuth = DrawAzimuth;
            this.Lenght = Lenght;
        }

        public Observer()
        {
            ser = new XmlSerializer(this.GetType());
        }
}

EDIT : my propose is to save list of objects.. if anyone have another idea i will be more than happy to learn. Thanks

Private fields don't serialize. Make properties that are public:

      [Serializable()]
  public class Observer : MapObject
  {

    private XmlSerializer ser;

    public int ID_Observer { get; set; }
    public double azimuth { get; set; }
    public double Long { get; set; }
    public double Lat { get; set; }
    public double Lenght { get; set; }
    public bool haveConnection { get; set; }
    public bool DrawAzimuth { get; set; }

    /// <summary>
    /// C'tor
    /// </summary>
    public Observer(int ID_Observer = 0, double azimuth = 0, double Lat = 0, double Long = 0, double Lenght = 0, bool haveConnection = true, bool DrawAzimuth = true)
    {
      this.ID_Observer = ID_Observer;
      this.azimuth = azimuth;
      this.Long = Long;
      this.Lat = Lat;
      this.haveConnection = haveConnection;
      this.DrawAzimuth = DrawAzimuth;
      this.Lenght = Lenght;
    }

    public Observer()
    {
      ser = new XmlSerializer(this.GetType());
    }
  }
