C#打印类PrintDocument、PrintDialog、PrintPreviewDialog使用示例

1.使用PrintDocument进行打印

using System;

using System.Drawing;

using System.Drawing.Printing;

using System.Windows.Forms;

namespace PrintTest

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

//实例化打印对象

PrintDocument printDocument1 = new PrintDocument();

//设置打印用的纸张,当设置为Custom的时候,可以自定义纸张的大小

printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);

//注册PrintPage事件,打印每一页时会触发该事件

printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);

//开始打印

printDocument1.Print();

}

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

{

//设置打印内容及其字体,颜色和位置

e.Graphics.DrawString("Hello World!", new Font(new FontFamily("黑体"), 24), System.Drawing.Brushes.Red, 50, 50);

}

}

}

2.使用PrintDialog增加打印对话框

using System;

using System.Drawing;

using System.Drawing.Printing;

using System.Windows.Forms;

namespace PrintTest

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

//实例化打印对象

PrintDocument printDocument1 = new PrintDocument();

//设置打印用的纸张,当设置为Custom的时候,可以自定义纸张的大小

printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);

//注册PrintPage事件,打印每一页时会触发该事件

printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);

//初始化打印对话框对象

PrintDialog printDialog1 = new PrintDialog();

//将PrintDialog.UseEXDialog属性设置为True,才可显示出打印对话框

printDialog1.UseEXDialog = true;

//将printDocument1对象赋值给打印对话框的Document属性

printDialog1.Document = printDocument1;

//打开打印对话框

DialogResult result = printDialog1.ShowDialog();

if (result == DialogResult.OK)

printDocument1.Print();//开始打印

}

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

{

//设置打印内容及其字体,颜色和位置

e.Graphics.DrawString("Hello World!", new Font(new FontFamily("黑体"), 24), System.Drawing.Brushes.Red, 50, 50);

}

}

}

打印对话框如下图所示。

3.使用PrintPreviewDialog增加打印预览对话框

using System;

using System.Drawing;

using System.Drawing.Printing;

using System.Windows.Forms;

namespace PrintTest

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

//实例化打印对象

PrintDocument printDocument1 = new PrintDocument();

//设置打印用的纸张,当设置为Custom的时候,可以自定义纸张的大小

printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);

//注册PrintPage事件,打印每一页时会触发该事件

printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);

//初始化打印预览对话框对象

PrintPreviewDialog printPreviewDialog1 = new PrintPreviewDialog();

//将printDocument1对象赋值给打印预览对话框的Document属性

printPreviewDialog1.Document = printDocument1;

//打开打印预览对话框

DialogResult result = printPreviewDialog1.ShowDialog();

if (result == DialogResult.OK)

printDocument1.Print();//开始打印

}

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

{

//设置打印内容及其字体,颜色和位置

e.Graphics.DrawString("Hello World!", new Font(new FontFamily("黑体"), 24), System.Drawing.Brushes.Red, 50, 50);

}

}

}

打印时,会显示下图所示预览画面。

注意:PrintDialog与PrintPreviewDialog位于名称空间System.Windows.Forms(程序集为System.Windows.Forms.dll)中,而PrintDocument位于名称空间System.Drawing.Printing(程序集为System.Drawing.dll)中。
