Replacing XML serialization of class member

In my class (Camera), that I need to serialize, I have one member which doesn't have much serialization means and I can't modify its class. But there are only 2-3 parameters out of whole class that I can serialize and then de-serialize based on that. 

XmlSerializer SerializerObj = new XmlSerializer(typeof(Camera));
TextWriter WriteFileStream = new StreamWriter(@"C:\test.xml");
SerializerObj.Serialize(WriteFileStream, cc);
WriteFileStream.Close();

How and where can I put custom serialization code, to take those 2-3 parameters from object and give to serializer, then during de-serialization create again that object using those 2-3 parameters.

Update. The example code:

[Serializable()]
public class Camera
{
    public string name;
    public int index;
    public double distance;
    public List<string> CameraList { get; set; }

    [XmlIgnore()]
    public GMarkerGoogle marker;

    public Camera()
    {
    }

}

marker is the member that doesn't have serialization means. But there with marker.position, marker.rotation I can re-create that object.

If you can't or don't want to Xml serialize your GMarker then make sure that you do serialize the properties needed to reconstruct it (kind of what you already suggested). That way you can make a property with backing field to lazy recreate the GMarker.

[Serializable()]
public class Camera
{
    public string name;
    public int index;
    public double distance;
    public List<string> CameraList { get; set; }

    private GMarkerGoogle _marker;
    [XmlIgnore()]
    public GMarkerGoogle Marker
    {
        set
        {
            _marker = value;
            MarkerPosition = _marker.position;
            MarkerRotation = _marker.rotation;
        }
        get
        {
            if (_marker == null)
            {
                _marker = new GMarkerGoogle(MarkerPosition, MarkerRotation);
            }

            return _marker;
        }
    }

    public double MarkerPosition { get; set; }
    public double MarkerRotation { get; set; }

    public Camera()
    {
    }
}

Does this help? I made up a thing or two because I don't know the API for the marker, but I hope you can draw the picture from this point onwards.

By implementing the IXmlSerializable interface in your Camera class.

Check MSDN for more info.

Alternatively you could use the [XmlIgnore] attribute to flag the properties you do not want to serialize to XML.

Check MSDN for more info :).

PS: If you post some code I can show you an example but you probably don't need me. Let me know if you do though.
