使用画刷对象：
画刷对象是用特定的颜色、模式或是图像来填充一块区域的。总共有四种类型的画刷：SolidBrush（默认的画刷）、HatchBrush、GradientBrush以及TexturedBrush。下面，我们分别给出实例来进行介绍。
1、运用SolidBrush：
using System;
using System.Windows.Forms;
using System.Drawing;
using System.Drawing.Drawing2D;
public class Solidbru:Form {
public Solidbru() {
this.Text = "运用SolidBrush示例";
this.Paint += new PaintEventHandler(Fill_Graph);
}
public void Fill_Graph(object sender,PaintEventArgs e) {
Graphics g = e.Graphics;
//创建一把SolidBrush并用它来填充一个矩形区域
SolidBrush sb = new SolidBrush(Color.Pink);
g.FillRectangle(sb,50,50,150,150);
}
public static void Main() {
Application.Run(new Solidbru());
}
}
using System.Windows.Forms;
using System.Drawing;
using System.Drawing.Drawing2D;
public class Solidbru:Form {
public Solidbru() {
this.Text = "运用SolidBrush示例";
this.Paint += new PaintEventHandler(Fill_Graph);
}
public void Fill_Graph(object sender,PaintEventArgs e) {
Graphics g = e.Graphics;
//创建一把SolidBrush并用它来填充一个矩形区域
SolidBrush sb = new SolidBrush(Color.Pink);
g.FillRectangle(sb,50,50,150,150);
}
public static void Main() {
Application.Run(new Solidbru());
}
}
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());
}
}
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());
}
}
