这篇文章主要介绍了C#打印类PrintDocument、PrintDialog、PrintPreviewDialog使用示例,本文分别给出了示例代码,需要的朋友可以参考下
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。
