protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);

Graphics g= e.Graphics;
Pen p=new Pen(Color.Blue);

Pen p2 = new Pen(Color.Red);

for (int i = 0; i < this.Width; i+=20)
{
g.DrawLine(p, new Point(i, 0), new Point(i, this.Height));
}

g.DrawLine(p2,new Point(0,this.Height/2), new Point(this.Width / 2, this.Height / 2));
g.DrawLine(p2, new Point(this.Width / 2, this.Height / 2), new Point(this.Width / 2 -5, this.Height / 2-5));
g.DrawLine(p2, new Point(this.Width / 2, this.Height / 2), new Point(this.Width / 2 - 5, this.Height / 2 + 5));
}

private void button1_Click(object sender, EventArgs e)
{

Point _StarPoint = new Point(0, 0);
Point _EndPoint = new Point(50, 50);

System.Drawing.Drawing2D.AdjustableArrowCap _LineCap = new System.Drawing.Drawing2D.AdjustableArrowCap(9, 9, false); //设置一个线头
Pen _Pen = new Pen(Brushes.Yellow, 1);
_Pen.CustomEndCap = (System.Drawing.Drawing2D.CustomLineCap)_LineCap;

Graphics _Graphics = Graphics.FromHwnd(pictureBox1.Handle); //刷子
_Graphics.DrawLine(_Pen, _StarPoint, _EndPoint);
_Graphics.Dispose();

}
