にXAMLするには、カスタムクラスの追加だから私はSprite.csこのクラスを作成しました：私は今、何をしたいかはWPF
class Sprite : INotifyPropertyChanged
{
double _Speed;
RectangleGeometry _SpriteRectangleGeometry;
Path _SpritePath;
public Sprite()
{
_SpriteRectangleGeometry = new RectangleGeometry();
_SpriteRectangleGeometry.Rect = new Rect(0, 0, 50, 50);
Speed = 50;
_SpritePath = new Path();
Color = Brushes.Black;
_SpritePath.Data = _SpriteRectangleGeometry;
}
public Sprite(double xpos, double ypos, double height, double width, double speed, SolidColorBrush color)
{
_SpriteRectangleGeometry = new RectangleGeometry();
_SpriteRectangleGeometry.Rect = new Rect(xpos, ypos, width, height);
this.Speed = speed;
_SpritePath = new Path();
this.Color = color;
_SpritePath.Data = _SpriteRectangleGeometry;
}
public double XPos
{
get { return _SpriteRectangleGeometry.Rect.X; }
set
{
_SpriteRectangleGeometry.Rect = new Rect(value, YPos, Width, Height);
//Notify the binding that the value has changed.
this.OnPropertyChanged("XPos");
}
}
public double YPos
{
get { return _SpriteRectangleGeometry.Rect.Y; }
set
{
_SpriteRectangleGeometry.Rect = new Rect(XPos, value, Width, Height);
//Notify the binding that the value has changed.
this.OnPropertyChanged("YPos");
}
}
public double Speed
{
get { return _Speed; }
set { _Speed = value; }
}
public double Width
{
get { return _SpriteRectangleGeometry.Rect.Width; }
set { _SpriteRectangleGeometry.Rect = new Rect(XPos, YPos, value, Height); }
}
public double Height
{
get { return _SpriteRectangleGeometry.Rect.Height; }
set { _SpriteRectangleGeometry.Rect = new Rect(XPos, YPos, Width, value); }
}
public SolidColorBrush Color
{
get { return (SolidColorBrush)_SpritePath.Fill; }
set { _SpritePath.Fill = value; }
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string strPropertyName)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(strPropertyName));
}
}
は、XAMLにスプライトのインスタンスを追加することですが、私が行うとき、私はこのエラーを取得します：
The value of type 'Sprite" cannot be added to collection or dictionary of type UIElementCollection
アドバイスはありますか？
