本篇文章為大家展示了C#中怎么實(shí)現(xiàn)打印條碼操作,內(nèi)容簡(jiǎn)明扼要并且容易理解,絕對(duì)能使你眼前一亮,通過這篇文章的詳細(xì)介紹希望你能有所收獲。
C#打印條碼操作的實(shí)例:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; //C#打印條碼操作的實(shí)例 namespace PrintDemo { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { tbBarCode.Focus(); } //C#打印條碼操作的實(shí)例 private void tbBarCode_KeyDown(object sender, KeyEventArgs e) { switch (e.KeyCode) { case Keys.Enter: PrintBarcode(tbBarCode.Text.Trim()); tbBarCode.Text = ""; tbBarCode.Focus(); break; default: break; } } private void PrintBarcode(string Barcode) { Barcode = "^XA^FO48,12^BY4^BCN,152,N,N^FD>;" + //C#打印條碼操作的實(shí)例 Barcode.Trim() + "^FS^FT62,220^CI0^ABN,44,28^FD" + Barcode.Trim() + "^FS^PQ1,0,1,Y^XZ"; PrintDemo.POSPrinter prn = new PrintDemo.POSPrinter("LPT1"); string strmsg = prn.PrintLine(Barcode); if (strmsg != "") { MessageBox.Show(strmsg); } } } }
C#打印條碼操作之類POSPrinter定義如下
namespace PrintDemo { class POSPrinter { const int OPEN_EXISTING = 3; string prnPort = "LPT1"; [DllImport("kernel32.dll", CharSet = CharSet.Auto)] private static extern IntPtr CreateFile(string lpFileName, int dwDesiredAccess, int dwShareMode, int lpSecurityAttributes, int dwCreationDisposition, int dwFlagsAndAttributes, int hTemplateFile); public POSPrinter() { // // TODO: 在此處添加構(gòu)造函數(shù)邏輯 // } public POSPrinter(string prnPort) { this.prnPort = prnPort;//打印機(jī)端口 } public string PrintLine(string str) { IntPtr iHandle = CreateFile(prnPort, 0x40000000, 0, 0, OPEN_EXISTING, 0, 0); if (iHandle.ToInt32() == -1) { return "LPT1 Port Open Failed"; } else { FileStream fs = new FileStream(iHandle, FileAccess.ReadWrite); StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.Default);//C#打印條碼操作之寫數(shù)據(jù) sw.WriteLine(str); sw.Close(); fs.Close(); return ""; } } } }
