Standard 2 of 5

Code 128

Code 128-A

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;            }        }///  /// Class containing the description of the QR code and wrapping encoding and rendering. /// 
 internal class CodeDescriptor { public ErrorCorrectionLevel Ecl; public string Content; public QuietZoneModules QuietZones; public int ModuleSize; public BitMatrix Matrix; public string ContentType; ///  /// Parse QueryString that define the QR code properties /// 
 /// HttpRequest containing HTTP GET data /// 
     
      A QR code descriptor object
      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; } ///  /// Encode the content with desired parameters and save the generated Matrix /// 
 /// 
     
      True if the encoding succeeded, false if the content is empty or too large to fit in a QR code
      public bool TryEncode() { var encoder = new QrEncoder(Ecl); QrCode qr; if (!encoder.TryEncode(Content, out qr)) return false; Matrix = qr.Matrix; return true; } ///  /// Render the Matrix as a PNG image /// 
 /// MemoryStream to store the image bytes into 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：
