C# 打印窗体上的所有Lable和TextBox(可多个窗体)
新建一个类,全部代码如下:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Text;
using System.Drawing;
using System.Drawing.Printing;
using System.IO;
using System.Windows.Forms;
namespace System_Class
{
/// <summary>
/// 打印窗体上所有lalel和textbox的Text 正常
/// </summary>
public class PrintLblTb
{
private System.Drawing.Printing.PrintDocument docToPrint = new System.Drawing.Printing.PrintDocument();
protected PrintPreviewDialog printPreviewDialog = new PrintPreviewDialog();
private Form form = null;
private Form[] forms = null;
public PrintLblTb()
{
this.docToPrint.PrintPage += new PrintPageEventHandler(docToPrint_PrintPage);
}
/// <summary>
/// 开始打印
/// </summary>
/// <param name="f">当前窗体</param>
/// <param name="DocTitle">标题</param>
public void StartPrint(Form f, string DocTitle)
{
form = f;
System.Windows.Forms.PrintDialog PrintDialog1 = new PrintDialog();
PrintDialog1.AllowSomePages = true;
PrintDialog1.ShowHelp = true;
PrintDialog1.Document = docToPrint;
DialogResult result = PrintDialog1.ShowDialog();//调用PrintDialog的ShowDialog函数显示打印对话框
if (result == DialogResult.OK)
{
//docToPrint.Print();//开始打印
docToPrint.DocumentName = DocTitle;
docToPrint.PrinterSettings = PrintDialog1.PrinterSettings;
docToPrint.DefaultPageSettings = PrintDialog1.PrinterSettings.DefaultPageSettings;
//docToPrint.DefaultPageSettings.Landscape = true;
docToPrint.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
printPreviewDialog.Document = docToPrint;
printPreviewDialog.ShowDialog();
}
}
/// <summary>
/// 开始打印多个窗体
/// </summary>
/// <param name="f">窗体数组</param>
/// <param name="DocTitle">标题</param>
public void StartPrint(Form[] f, string DocTitle)
{
forms = f;
System.Windows.Forms.PrintDialog PrintDialog1 = new PrintDialog();
PrintDialog1.AllowSomePages = true;
PrintDialog1.ShowHelp = true;
PrintDialog1.Document = docToPrint;
DialogResult result = PrintDialog1.ShowDialog();//调用PrintDialog的ShowDialog函数显示打印对话框
if (result == DialogResult.OK)
{
//docToPrint.Print();//开始打印
docToPrint.DocumentName = DocTitle;
docToPrint.PrinterSettings = PrintDialog1.PrinterSettings;
docToPrint.DefaultPageSettings = PrintDialog1.PrinterSettings.DefaultPageSettings;
//docToPrint.DefaultPageSettings.Landscape = true;
docToPrint.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
printPreviewDialog.Document = docToPrint;
printPreviewDialog.ShowDialog();
}
}
private void docToPrint_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)//设置打印机开始打印的事件处理函数
{
//绘制label2中的内容
//e.Graphics.DrawString(label2.Text, new Font("宋体", 20, FontStyle.Regular), Brushes.Black, 270, 430);
//e.Graphics.DrawString(text, printFont, System.Drawing.Brushes.Black, e.MarginBounds.X, e.MarginBounds.Y);
//e.Graphics.DrawImage(image, destRect, 0, 0, image.Width, image.Height, System.Drawing.GraphicsUnit.Pixel);
//Font f=new Font("宋体",12, FontStyle.Regular);
int formTopHeight = 0;
//多个窗体
if (forms != null)
{
foreach( Form f in forms)
{
FindLableOrTextBox(f, f.Controls, e, formTopHeight);
formTopHeight += f.Height;
//string fg="-----------------------------------------------------------------------------------------";
//e.Graphics.DrawString(fg, new Font("宋体", 12, FontStyle.Regular), Brushes.Black, f.Left, f.Top + formTopHeight);
}
}
else if (form != null)
{
FindLableOrTextBox(form, form.Controls, e,formTopHeight);
}
}
/// <summary>
/// 为每一个Label和TextBox绘图
/// </summary>
/// <param name="O">父对像</param>
/// <param name="CS">控件集</param>
/// <param name="e">绘制事件</param>
private void FindLableOrTextBox(Object O,Control.ControlCollection CS, System.Drawing.Printing.PrintPageEventArgs e,int TopH)
{
foreach (Control cot in CS)
{
if (typeof(Button) != cot.GetType())//typeof(Label) == cot.GetType() || typeof(TextBox) == cot.GetType()
{
float ptop = 0;
if (O.GetType() == typeof(Panel))
{
Panel p = O as Panel;
ptop = p.Top;
}
if(!cot.Text.Equals("*"))
e.Graphics.DrawString(cot.Text, cot.Font, Brushes.Black, cot.Left, cot.Top + ptop + TopH);
}
if (cot.Controls.Count > 0) FindLableOrTextBox(cot,cot.Controls,e,TopH);
}
}
}
}
调用如下:
多窗体:
TDJXC.Fees.Print1 p1 = new Print1(_umode,_mode,1,lblAll.Text);
TDJXC.Fees.Print1 p2 = new Print1(_umode, _mode, 2, lblAll.Text);
Form[] fs = { this, p1, p2 };
System_Class.PrintLblTb scp = new System_Class.PrintLblTb();
scp.StartPrint(fs,"打印收据");
单窗体
System_Class.PrintLblTb scp = new System_Class.PrintLblTb();
scp.StartPrint(this,"打印收据");
