C# 绘制简单三角形
作者:互联网
先来个等边倒三角形练手:
点1 0,0
点2 100,0
点3 cos(60),sin(60)
var p4 = new Point(); p4.X = 0; p4.Y = 0; var p5 = new Point(); p5.X = width; p5.Y = 0; a = 60; // 角度 var p6 = new Point(); p6.X = (int)(0 + width * (Math.Cos(Math.PI *a/180d))); p6.Y = (int)(0 + width * (Math.Sin(Math.PI *a/180d))); points[0] = p4; points[1] = p5; points[2] = p6; points[3] = p4; Graphics g = e.Graphics; var p = new Pen(Color.Black); g.DrawLines(p, points);
