命名空间：System.Drawing.Drawing2D.HatchBrush
在创建笔刷时，需要传入参数
1.阴影样式HatchStyle
2.前景色
3.背景色
Brush brs1 = new HatchBrush(参数1,参数2, 参数3);
参数1中HatchStyle为枚举值，且枚举很多有0-52，突发奇想，想试试每种笔刷的效果，结果如下，可供参考：
测试代码，使用循环生成枚举笔刷绘制：
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
string code = GetAllBrushCode();
}
private void Form1_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
Point start = new Point(50, 50);
Point end = new Point(300, 50);
//前景色
Color color1 = Color.Blue;
//背景色
Color color2 = Color.Yellow;
//每根线之间的间距
int margin = 10;
//每个笔刷的宽度
int pwidth = 10;
//笔刷
//1.颜色笔刷
Brush br1 = new SolidBrush(Color.Black);
Pen p1 = new Pen(br1, pwidth);
g.DrawLine(p1, NewPoint(start, 0), NewPoint(end, 0));
//2.阴影画刷
