可以自定义短划线，如
float[] f = { 15, 5, 10, 5 };
p.DashPattern = f;
f = { 15, 5, 10, 5 };表示短划线时这4个元素的循环15像素的短线，接着是5像素的空隙，接着又是10像素的短线和5像素的空隙
例如：
1
private
void
Form1_Paint(
object
sender, PaintEventArgs e)
2 {
3 Graphics g = e.Graphics;
4 g.FillRectangle(Brushes.White, this .ClientRectangle);
5 Pen p = new Pen(Color.Black, 1 );
6 float [] f = { 15 , 5 , 10 , 5 };
7 p.DashPattern = f;
8 g.DrawRectangle(p, 10 , 10 , 80 , 200 );
9 p.Dispose();
10 }
2 {
3 Graphics g = e.Graphics;
4 g.FillRectangle(Brushes.White, this .ClientRectangle);
5 Pen p = new Pen(Color.Black, 1 );
6 float [] f = { 15 , 5 , 10 , 5 };
7 p.DashPattern = f;
8 g.DrawRectangle(p, 10 , 10 , 80 , 200 );
9 p.Dispose();
10 }
其他的一些画笔设置示例
p.DashStyle =DashStyle.Solid;
p.DashStyle =DashStyle.Dash;
p.DashStyle =DashStyle.DashDot;
p.DashStyle =DashStyle.DashDotDot;
p.DashStyle =DashStyle.Dot;
