C# 如何绘制平行四边形集合线

protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
Rectangle[] rectangles = new Rectangle[]
{
new Rectangle(0, 0, 100, 30),
new Rectangle(100, 0, 100, 30),
new Rectangle(200, 0, 100, 30),
new Rectangle(300, 0, 100, 30),
new Rectangle(400, 0, 100, 30),
};
e.Graphics.DrawRectangles(new Pen(Brushes.Black), rectangles);
}
我的问题是,我需要将矩形转换为平行四边形,并为每个矩形赋予不同的颜色。填充多边形可以完成以下工作:
protected override void OnPaint(PaintEventArgs e) {
base.OnPaint(e);
e.Graphics.Clear(Color.White);
int x = 10;
int y = 10;
int width = 148;
int height = 64;
int lean = 36;
Color[] colors = new[] { Color.FromArgb(169, 198, 254),
Color.FromArgb(226, 112, 112),
Color.FromArgb(255, 226, 112),
Color.FromArgb(112, 226, 112),
Color.FromArgb(165, 142, 170)};
e.Graphics.SmoothingMode = SmoothingMode.AntiAlias;
for (int i = 0; i < colors.Length; ++i) {
using (SolidBrush br = new SolidBrush(colors[i])) {
e.Graphics.FillPolygon(br, new Point[] { new Point(x, y),
new Point(x + lean, y + height),
new Point(x + lean + width, y + height),
new Point(x + width, y)});
x += width;
}
}
}
protected override void OnPaint(PaintEventArgs e){
基础漆(e);
e、 图形。清晰(颜色。白色);
int x=10;
int y=10;
整数宽度=148;
整数高度=64;
int-lean=36;
Color[]colors=new[]{Color.FromArgb(169198254),
颜色。来自argb(226112112),
颜色。来自argb(255、226、112),
颜色。来自argb(112226112),
Color.FromArgb(165、142、170)};
e、 Graphics.SmoothingMode=SmoothingMode.AntiAlias;
对于(int i=0;i
/还有FillPolygon和DrawPolygon!
