Xml serialization c#

Can't understand what I am doing wrong, the result set is empty.
My code:

class Class1
    {

        public static object DeSerialize()
        {
            object resultObject;

            XmlSerializer serializer = new XmlSerializer(typeof(PointsContainer));
           using (TextReader textReader = new StreamReader(@"d:\point.xml"))
            {
                resultObject = serializer.Deserialize(textReader);
            }

            return resultObject;


        }
    }

    [Serializable]
    [XmlRoot("Points")]
    public class PointsContainer
    {
        [XmlElement("Point")]       
        private List<Point> items = new List<Point>();

        public List<Point> Items
        {
            get { return items; }
            set { items = value; }
        }


    }


    [Serializable]   
    public class Point
    {      
        [XmlAttribute]
        public bool x { get; set; }

        [XmlAttribute]
        public bool y { get; set; }
    }

Xml:

<Points>  
   <Point x="1" y="5"/>
   <Point x="21" y="3"/>
   <Point x="3" y="7"/>
</Points>

You could using a DeSerialize function that return the object type like this example: 

public T DeSerializeFromString<T>(string data)
        {
            T result;
            StringReader rdr = null;
            try
            {
                rdr = new StringReader(data);
                XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
                result = (T)xmlSerializer.Deserialize(rdr);
            }
            catch (Exception)
            {
                throw;
            }
            finally
            {
                rdr.Close();
            }
            return result;
        }

Solution:

namespace XmlStackProblem
{
    class Class1
    {

        public static void Main()
        {
            Points resultObject;

            XmlSerializer serializer = new XmlSerializer(typeof(Points));
            using (TextReader textReader = new StreamReader(@"d:\points.xml"))
            {
                resultObject = serializer.Deserialize(textReader) as Points;
            }
        }
    }

    [Serializable]
    [XmlRoot(IsNullable = false)]
    public class Points
    {
        [XmlElementAttribute("Point")]
        public List<Point> Point
        {
            get; set;
        }
    }

    [Serializable]
    [XmlType(AnonymousType = true)]
    public class Point
    {
        [XmlAttribute]
        public int x
        {
            get;
            set;
        }

        [XmlAttribute]
        public int y { get; set; }
    }
}

[XmlElement("Point")]
public List<Point> Items
{
  get { return items; }
  set { items = value; }
}

And in your point class both x and y should not be bools.

bool variables can either be true or false which have an integer value of 1 and 0. So your XML has invalid data and/or your class properties are of the wrong type.

as SLaks says

also your Point object shows both fields as bools yet the values in the xml file are ints at least (21, 3,5,7 etc)

Move the [XmlElement] attribute to the property.
XmlSerializer ignores private members.
