学习c# winform 打印 参照了网络上诸多资源

效果示意：





操作步骤：

1、新建winform项目及创建窗体

2、拖取 打印 相关控件

PageSetupDialog 、 PrintDialog 、 PrintDocument 、PrintPreviewDialog

3、设置上述控件的Document属性为相应的PrintDocument

4、设置按钮等控件 及 添加相应按钮事件

5、示意代码如下




代码

public partial class Form3 : Form

{

public Form3()

{

InitializeComponent();

this.printDocument1.OriginAtMargins = true;//启用页边距

this.pageSetupDialog1.EnableMetric = true; //以毫米为单位

}

//打印设置

private void btnSetPrint_Click(object sender, EventArgs e)

{

this.pageSetupDialog1.ShowDialog();

}

//打印预览

private void btnPrePrint_Click(object sender, EventArgs e)

{

this.printPreviewDialog1.ShowDialog();

}

//打印

private void btnPrint_Click(object sender, EventArgs e)

{

if (this.printDialog1.ShowDialog() == DialogResult.OK)

{

this.printDocument1.Print();

}

}

//打印内容的设置

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)

{

////打印内容 为 整个Form

//Image myFormImage;

//myFormImage = new Bitmap(this.Width, this.Height);

//Graphics g = Graphics.FromImage(myFormImage);

//g.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);

//e.Graphics.DrawImage(myFormImage, 0, 0);

////打印内容 为 局部的 this.groupBox1

//Bitmap _NewBitmap = new Bitmap(groupBox1.Width, groupBox1.Height);

//groupBox1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));

//e.Graphics.DrawImage(_NewBitmap, 0, 0, _NewBitmap.Width, _NewBitmap.Height);

//打印内容 为 自定义文本内容

Font font = new Font("宋体", 12);

Brush bru = Brushes.Blue;

for (int i = 1; i <= 5; i++)

{

e.Graphics.DrawString("Hello world ", font, bru, i*20, i*20);

}

}

}
