目前我正在开发一个项目，该项目涉及在WPF中设置自定义构建的2D形状。形状看起来像一个盒子，目前我似乎有一些小问题。
这是我的代码目前的样子
namespace Wpftrial4
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
SolidColorBrush fillcolor = new SolidColorBrush();
SolidColorBrush bordercolor = new SolidColorBrush();
public MainWindow()
{
InitializeComponent();
fillcolor.Color = Colors.WhiteSmoke;
bordercolor.Color = Colors.Blue;
}
private void button1_Click(object sender, RoutedEventArgs e)
{
//Manually creating the required 2D Box shape
Path path_rectangle = new Path();
path_rectangle.Fill = fillcolor;
path_rectangle.Stroke = bordercolor;
path_rectangle.StrokeThickness = 5;
RectangleGeometry rg = new RectangleGeometry();
double width_rec = 100;
double height_rec = 50;
double left_rec = 130;
double top_rec = 100;
rg.Rect = new Rect(left_rec, top_rec, width_rec, height_rec);
path_rectangle.Data = rg;
canvas1.Children.Add(path_rectangle);
Path path2_top = new Path();
path2_top.Stroke = new SolidColorBrush(Colors.Brown);
path2_top.StrokeThickness = 6;
RectangleGeometry rg2 = new RectangleGeometry();
double width2 = 100;
double height2 = 2;
double left2 = 130;
double top2 = 90;
rg2.Rect = new Rect(left2, top2, width2, height2);
path2_top.Data = rg2;
canvas1.Children.Add(path2_top);
Path path3_topcover = new Path();
path3_topcover.Stroke = new SolidColorBrush(Colors.White);
path3_topcover.StrokeThickness = 5;
RectangleGeometry rg3 = new RectangleGeometry();
double width3 = 100;
double height3 = 5;
double left3 = 130;
double top3 = 100;
rg3.Rect = new Rect(left3, top3, width3, height3);
path3_topcover.Data = rg3;
canvas1.Children.Add(path3_topcover);
//combining part_Group type
GeometryGroup myGeometryGroup = new GeometryGroup();
myGeometryGroup.Children.Add(rg);
myGeometryGroup.Children.Add(rg3);
Path myPath = new Path();
myPath.Stroke = Brushes.Blue;
myPath.Data = myGeometryGroup;
canvas1.Children.Add(myPath);
////test animate
//myCustomAnimatedBox MB2 = new myCustomAnimatedBox(200, 200, 300, 250) { Stroke = Brushes.Black, StrokeThickness = 2 };
//canvas1.Children.Add(MB2); //new myCustomAnimatedBox(200, 200, 300, 250,500,500){Stroke = Brushes.Black, StrokeThickness = 2});
//PointAnimation pa2 = new PointAnimation();
////DoubleAnimation da = new DoubleAnimation();
//pa2.To = new Point(100, 100);

//pa2.Duration = TimeSpan.FromSeconds(10);
////MB2.BeginAnimation(myCustomAnimatedBox.TopProperty,pa2);//(//MB2.BeginAnimation(myCustomAnimatedBox.CenterProperty, pa2);
}
//class- style custom2D shape creation
private void button2_Click(object sender, RoutedEventArgs e)
{
myCustomAnimatedBox MB = new myCustomAnimatedBox(200, 200, 350, 250) { Stroke = Brushes.Black, StrokeThickness = 2 };
canvas1.Children.Add(MB); //new myCustomAnimatedBox(200, 200, 300, 250,500,500){Stroke = Brushes.Black, StrokeThickness = 2});
//PointAnimation pa = new PointAnimation();
////DoubleAnimation da = new DoubleAnimation();
//pa.To = new Point(100, 100);
////da.By = 50;
//pa.Duration = TimeSpan.FromSeconds(10);
//MB.BeginAnimation(myCustomAnimatedBox.CenterProperty, pa);
}
}
//Class that defines the custom 2D shape
public class myCustomAnimatedBox : Shape
{
private double x1, width;
private double y1, height;
private GeometryGroup myBox = new GeometryGroup();
public myCustomAnimatedBox(double XX1, double YY1, double widTH, double heiGHT)
{
makeBox(XX1, YY1, widTH, heiGHT);
}
//public static readonly DependencyProperty CenterProperty = DependencyProperty.Register("Center", typeof(Point), typeof(myCustomAnimatedBox),

////new Point(cent_X, cent_Y)
//public Point Center

set
{

}
}
public double Y1
{

set
{
y1 = value;
}
}
//Trial at creating a dependency property
//private static void TopPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
//{
// myCustomAnimatedBox myB = (myCustomAnimatedBox)d;
// myB.InvalidateVisual();
//}
protected override Geometry DefiningGeometry
{
get { return myBox; }
}
//Function that draws the object
private void makeBox(double XX1, double YY1, double widTH, double heiGHT)
{
width = widTH;
height = heiGHT;
this.X1 = XX1;
this.Y1 = YY1;
RectangleGeometry rectangle_part = new RectangleGeometry();
rectangle_part.Rect = new Rect(X1,Y1,width,height);
RectangleGeometry rg_cover = new RectangleGeometry();
RectangleGeometry rg_top = new RectangleGeometry();
rg_top.Rect = new Rect(X1, Y1 - 10, width, 2);
rg_cover.Rect = new Rect(X1, Y1, width, 5);
myBox.Children.Add(rectangle_part);
myBox.Children.Add(rg_top);
myBox.Children.Add(rg_cover);
}
}
}
由于形状将经历动画，例如：盒子打开和关闭，我需要自定义形状以具有可移动部分。根据大多数作者的GeometryGroup似乎在动画加上其他数据绑定时提供了最大的优势。在我测试的代码中手动创建形状。这可以在附加到Button1的代码中看到。然而，当我尝试进行类实现时，我无法获得我想要的那种效果，例如改变单个组成特征。我在WPF学习不到1个月，希望在以下方面提供帮助。
感谢您的帮助。

制作动画2d形状的最佳选择是使用表达式混合软件：Download link software 你可以在这里看到一个示例教程：Introduction to Blend: Animation
