2、运用HatchBrush：
using System;
using System.Windows.Forms;
using System.Drawing;
using System.Drawing.Drawing2D;
public class Hatchbru:Form {
public Hatchbru() {
this.Text = "运用HatchBrush示例";
this.Paint += new PaintEventHandler(Fill_Graph);
}
public void Fill_Graph(object sender,PaintEventArgs e) {
Graphics g = e.Graphics;
//创建一把HatchBrush并用它来填充一个矩形区域
/*该画刷的HatchStyle有DiagonalCross、
ForwardDiagonal、Horizontal、 Vertical、 Solid等不同风格 */
HatchStyle hs = HatchStyle.Cross;
HatchBrush sb = new HatchBrush(hs,Color.Blue,Color.Red);
g.FillRectangle(sb,50,50,150,150);
}
public static void Main() {
Application.Run(new Hatchbru());
}
} |
3、运用GradientBrush：
GradientBrush又可分为LinearGradientBrush和PathGradientBrush两种，从它们的名称我们可以知道前者是线性渐变的，而后者则是路径渐变的，因而能创造出更复杂和完美的效果。下面我就给大家分别举例：
1）、运用LinearGradientBrush：
using System;
using System.Windows.Forms;
using System.Drawing;
using System.Drawing.Drawing2D;
public class LinearGradientbru:Form {
public LinearGradientbru() {
this.Text = "运用LinearGradientBrush示例";
this.Paint += new PaintEventHandler(Fill_Graph);
}
public void Fill_Graph(object sender,PaintEventArgs e) {
Rectangle r = new Rectangle(500, 300, 100, 100);
LinearGradientBrush lb = new LinearGradientBrush(r, Color.Red, Color.Yellow,
LinearGradientMode.BackwardDiagonal);
e.Graphics.FillRectangle(lb, r);
}
public static void Main() {
Application.Run(new LinearGradientbru());
}
}

2）、运用PathGradientBrush：
using System;
using System.Windows.Forms;
using System.Drawing;
using System.Drawing.Drawing2D;
public class PathGradientbru:Form {
public PathGradientbru() {
this.Text = "运用PathGradientBrush示例";
this.Paint += new PaintEventHandler(Fill_Graph);
}
public void Fill_Graph(object sender,PaintEventArgs e) {
e.Graphics.TextRenderingHint = TextRenderingHint.AntiAliased;
e.Graphics.FillRectangle(backgroundBrush, ClientRectangle);
e.Graphics.FillRectangle(new SolidBrush(Color.FromArgb(180, Color.White)), ClientRectangle);
//先设置好一个路径
GraphicsPath path = new GraphicsPath(new Point[] {
new Point(40, 140),
new Point(275, 200),
new Point(105, 225),
new Point(190, 300),
new Point(50, 350),
new Point(20, 180),
}, new byte[] {
(byte)PathPointType.Start,
(byte)PathPointType.Bezier,
(byte)PathPointType.Bezier,
(byte)PathPointType.Bezier,
(byte)PathPointType.Line,
(byte)PathPointType.Line,
});
//创建一把PathGradientBrush
PathGradientBrush pgb = new PathGradientBrush(path);
//设置画刷的周围颜色
pgb.SurroundColors = new Color[] {
Color.Green,
Color.Yellow,
Color.Red,
Color.Blue,
Color.Orange,
Color.White,
};
//用画刷进行填充
e.Graphics.FillPath(pgb, path);
}
public static void Main() {
Application.Run(new PathGradientbru());
}
