C#的箭头画法

时间：2011-05-07 来源：孤独的猫

可以用Pen(画笔)的StartCap和EndCap定义箭头的起止形状，再用DrawLine画出

 1 private void Form1_Paint(object sender, PaintEventArgs e)
 2 {
 3      Graphics g = e.Graphics;
 4      g.SmoothingMode = SmoothingMode.AntiAlias;
 5      g.FillRectangle(Brushes.White, this.ClientRectangle);
 6 
 7      Pen p = new Pen(Color.Black, 10);
 8      p.StartCap = LineCap.Round;
 9      p.EndCap = LineCap.ArrowAnchor;
10      g.DrawLine(p, 30, 30, 80, 30);
11      p.Dispose();
12 }
