在WPF中,创建六边形的方法有很多。本文将介绍一种简单的方法,通过继承Shape类并使用PathGeometry来实现。
public class Hexagon : Shape
{
// class implementation
}
protected override Geometry DefiningGeometry
{
get
{
PathGeometry geometry = new PathGeometry();
// create lines to define the hexagon
List<LineSegment> lines = new List<LineSegment>()
{
new LineSegment(new Point(0, 0.5), true),
new LineSegment(new Point(0.25, 0.75), true),
new LineSegment(new Point(0.75, 0.75), true),
new LineSegment(new Point(1, 0.5), true),
new LineSegment(new Point(0.75, 0.25), true),
new LineSegment(new Point(0.25, 0.25), true)
};
// create a path figure with the lines
PathFigure figure = new PathFigure(new Point(0, 0.5), lines, true);
// add the figure to the geometry
geometry.Figures.Add(figure);
// return the geometry
return geometry;
}
}
Hexagon hexagon = new Hexagon();
hexagon.Width = 100;
hexagon.Height = 100;
hexagon.Fill = Brushes.Yellow;
hexagon.Stroke = Brushes.Black;
// add the hexagon to the UI
canvas.Children.Add(hexagon);
上述方法可以创建简单的六边形,也可通过修改几何描述来创建其他形状,例如正多边形、星形等。使用此方法可以轻松地在WPF应用程序中添加自定义形状。
