C#-Winform-打印控件

控件设计：
设置上述出去Button和Form控件的剩余控件（PrintDialog1等）的Document属性为相应的PrintDocument。
代码：

13     public partial class Form1 : Form
14     {
15         public Form1()
16         {
17             InitializeComponent();
18 
19             this.printDocument1.OriginAtMargins = true;//启用页边距
20             this.pageSetupDialog1.EnableMetric = true; //以毫米为单位
21         }
22 
23         /// <summary>
24         /// 打印
25         /// </summary>
26         private void button1_Click(object sender, EventArgs e)
27         {
28             if (this.printDialog1.ShowDialog() == DialogResult.OK)
29             {
30                 this.printDocument1.Print();
31             }
32         }
33 
34         /// <summary>
35         /// 打印设置
36         /// </summary>
37         private void button2_Click(object sender, EventArgs e)
38         {
39             this.pageSetupDialog1.ShowDialog(); 
40         }
41 
42         /// <summary>
43         /// 打印预览
44         /// </summary>
45         private void button3_Click(object sender, EventArgs e)
46         {
47             this.printPreviewDialog1.ShowDialog(); 
48         }
49 
50         private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
51         {
52             ////----------------打印内容 为 整个Form----------------
53             //Image myFormImage;
54             //myFormImage = new Bitmap(this.Width, this.Height);
55             //Graphics g = Graphics.FromImage(myFormImage);
56             //g.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);
57             //e.Graphics.DrawImage(myFormImage, 0, 0);
58 
59             ////----------------打印内容 为 局部的 this.groupBox1----
60             //Bitmap _NewBitmap = new Bitmap(groupBox1.Width, groupBox1.Height);
61             //groupBox1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));
62             //e.Graphics.DrawImage(_NewBitmap, 0, 0, _NewBitmap.Width, _NewBitmap.Height); 
63 
64             //------------------打印内容 为 自定义文本内容------------
65             Font font = new Font("宋体", 12);
66             Brush bru = Brushes.Blue;
67             //for (int i = 1; i <= 5; i++)
68             //{
69                 
70             //}
71             e.Graphics.DrawString("Hello world ", font, bru, 10, 10);
72         }
73     }
74 }
完成。
