C# 利用BarcodeLib.dll生成条形码（一维，zxing,QrCodeNet/dll二维码）

原文：http://blog.csdn.net/kongwei521/article/details/17588825

首先效果：



1:首先下载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。

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[b] 项目参照引用[/b]

{ 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); }

利用 QrCodeNet.dll生成条形码和二维码 下载地址http://qrcodenet.codeplex.com/

下载[b]QrCodeNet.dll 项目参照引用[/b]

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：
