首先效果：
一、下载BarcodeLib.dll
下载地址 ：http://download.csdn.net/detail/lllooollpp/7961715
源码：https://github.com/hjgode/barcodeLib
1.BarcodeLib.dll 一维条码库支持以下条码格式
UPC-A
UPC-E
UPC 2 Digit Ext.
UPC 5 Digit Ext.
EAN-13
JAN-13
EAN-8
ITF-14
Codabar
PostNet
Bookland/ISBN
Code 11
Code 39
Code 39 Extended
Code 93
LOGMARS
MSI
Interleaved 2 of 5
Standard 2 of 5
Code 128
Code 128-A
Code 128-B
Code 128-C
Telepen
然后项目中添加引用
private void button6_Click(object sender, EventArgs e) { System.Drawing.Image image; int width = 148, height = 55; string fileSavePath = AppDomain.CurrentDomain.BaseDirectory + "BarcodePattern.jpg"; if (File.Exists(fileSavePath)) File.Delete(fileSavePath); GetBarcode(height, width, BarcodeLib.TYPE.CODE128, "20131025-136", out image, fileSavePath); pictureBox1.Image = Image.FromFile("BarcodePattern.jpg"); } public static void GetBarcode(int height, int width, BarcodeLib.TYPE type, string code, out System.Drawing.Image image, string fileSaveUrl) { try { image = null; BarcodeLib.Barcode b = new BarcodeLib.Barcode(); b.BackColor = System.Drawing.Color.White;//图片背景颜色 b.ForeColor = System.Drawing.Color.Black;//条码颜色 b.IncludeLabel = true; b.Alignment = BarcodeLib.AlignmentPositions.LEFT; b.LabelPosition = BarcodeLib.LabelPositions.BOTTOMCENTER;//code的显示位置 b.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;//图片格式 System.Drawing.Font font = new System.Drawing.Font("verdana", 10f);//字体设置 b.LabelFont = font; b.Height = height;//图片高度设置(px单位) b.Width = width;//图片宽度设置(px单位) image = b.Encode(type, code);//生成图片 image.Save(fileSaveUrl, System.Drawing.Imaging.ImageFormat.Jpeg); } catch (Exception ex) { image = null; } }
简单的写一下。详细的去 http://www.barcodelib.com/net_barcode/main.html 这里看。
二、利用 zxing.dll生成条形码和二维码
下载地址http://zxingnet.codeplex.com/
ZXing (ZebraCrossing)是一个开源的，支持多种格式的条形码图像处理库， 。使用该类库可以方便地实现二维码图像的生成和解析。
下载zxing.dll 项目参照引用
{ MultiFormatWriter mutiWriter = new com.google.zxing.MultiFormatWriter(); ByteMatrix bm = mutiWriter.encode(txtMsg.Text, com.google.zxing.BarcodeFormat.QR_CODE, 300, 300); Bitmap img = bm.ToBitmap(); pictureBox1.Image = img; //自动保存图片到当前目录 string filename = System.Environment.CurrentDirectory + "\\QR" + DateTime.Now.Ticks.ToString() + ".jpg"; img.Save(filename, System.Drawing.Imaging.ImageFormat.Jpeg); lbshow.Text = "图片已保存到：" + filename; } catch (Exception ee) { MessageBox.Show(ee.Message); }
三、 QrCodeNet.dll生成条形码和二维码
下载地址http://qrcodenet.codeplex.com/
下载QrCodeNet.dll 项目参照引用
private void button2_Click(object sender, EventArgs e) { var codeParams = CodeDescriptor.Init(ErrorCorrectionLevel.H, textBox1.Text.Trim(), QuietZoneModules.Two, 5); codeParams.TryEncode(); // Render the QR code as an image using (var ms = new MemoryStream()) { codeParams.Render(ms); Image image = Image.FromStream(ms); pictureBox1.Image = image; if (image != null) pictureBox1.SizeMode = image.Height > pictureBox1.Height ? PictureBoxSizeMode.Zoom : PictureBoxSizeMode.Normal; } } /// <summary> /// Class containing the description of the QR code and wrapping encoding and rendering. /// </summary> internal class CodeDescriptor { public ErrorCorrectionLevel Ecl; public string Content; public QuietZoneModules QuietZones; public int ModuleSize; public BitMatrix Matrix; public string ContentType; /// <summary> /// Parse QueryString that define the QR code properties /// </summary> /// <param name="request">HttpRequest containing HTTP GET data</param> /// <returns>A QR code descriptor object</returns> public static CodeDescriptor Init(ErrorCorrectionLevel level, string content, QuietZoneModules qzModules, int moduleSize) { var cp = new CodeDescriptor(); //// Error correction level cp.Ecl = level; //// Code content to encode cp.Content = content; //// Size of the quiet zone cp.QuietZones = qzModules; //// Module size cp.ModuleSize = moduleSize; return cp; } /// <summary> /// Encode the content with desired parameters and save the generated Matrix /// </summary> /// <returns>True if the encoding succeeded, false if the content is empty or too large to fit in a QR code</returns> public bool TryEncode() { var encoder = new QrEncoder(Ecl); QrCode qr; if (!encoder.TryEncode(Content, out qr)) return false; Matrix = qr.Matrix; return true; } /// <summary> /// Render the Matrix as a PNG image /// </summary> /// <param name="ms">MemoryStream to store the image bytes into</param> internal void Render(MemoryStream ms) { var render = new GraphicsRenderer(new FixedModuleSize(ModuleSize, QuietZones)); render.WriteToStream(Matrix, System.Drawing.Imaging.ImageFormat.Png, ms); ContentType = "image/png"; } }
效果：
