推荐答案

绘制椭圆形非常简单:您所需要做的就是调用 Graphics.DrawElipse [ ^ ]方法在适当的Graphics上下文中.

最简单的方法是处理(例如)面板的Paint事件-这将为您提供面板的Graphics上下文，作为PaintEventArgs参数的Graphics属性.

Drawing an oval is pretty easy: all you need to do is call one of the Graphics.DrawElipse[^] methods on the appropriate Graphics context.

The easiest way is to handle the Paint Event for (say) a Panel - that will give you the Graphics context for the panel as the Graphics property of the PaintEventArgs parameter.

e.Graphics.DrawEllipse(Pens.Black, e.ClipRectangle)
