Simply write it. Go to http://www.barcodelib.com/net_barcode/main.html to see it in detail.

Use Zxing.dll to generate barcodes and QR codes http://zxingnet.codeplex.com/

ZXing (zebracrossing) is an open source, support multi-format barcode image processing library. Using this kind of library can easily realize the generation and resolution of two-dimensional code image.

Download zxing.dll Project reference Reference

{multiformatwriter Mutiwriter=NewCom.google.zxing.MultiFormatWriter (); Bytematrix BM= Mutiwriter.encode (Txtmsg.text, Com.google.zxing.BarcodeFormat.QR_CODE, -, -); Bitmap img=BM.                Tobitmap (); pictureBox1.Image=img; //automatically save pictures to current directory                stringfilename = System.Environment.CurrentDirectory +"\\QR"+ DateTime.Now.Ticks.ToString () +". jpg"; Img.                Save (filename, System.Drawing.Imaging.ImageFormat.Jpeg); Lbshow. Text="the picture has been saved to:"+filename; }            Catch(Exception ee) {MessageBox.Show (EE. Message); }

use QrCodeNet.dll to generate barcodes and QR codes http://qrcodenet.codeplex.com/
