推荐答案

如果你的意思是如何创建一个多边形而不是矩形的自定义控件？

然后它非常简单：在它的构造函数中将Region Property设置为你想要的形状：

If you mean "how do I create a custom control that is polygonal rather than rectangular?"
Then it's surprisingly easy: in it's constructor set the Region Property to the shape you want:

GraphicsPath path = new GraphicsPath();
path.AddLines(new Point[] { new Point(0,0), new Point(Width, 0), new Point(Width / 2, Height), new Point(0,0)});
Region = new Region(path);

例如，创建一个三角形。

Creates a triangle, for example.

下面是如何使用c＃绘制多边形的示例。

Below is the sample how to draw a Polygon by using c#.

public void DrawPolygonPoint(PaintEventArgs e)
{

    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);

    // Create points that define polygon.
    Point point1 = new Point(50,  50);
    Point point2 = new Point(100,  25);
    Point point3 = new Point(200,   5);
    Point point4 = new Point(250,  50);
    Point point5 = new Point(300, 100);
    Point point6 = new Point(350, 200);
    Point point7 = new Point(250, 250);
    Point[] curvePoints =
             {
                 point1,
                 point2,
                 point3,
                 point4,
                 point5,
                 point6,
                 point7
             };

    // Draw polygon to screen.
    e.Graphics.DrawPolygon(blackPen, curvePoints);
}
