首先效果：

一、下载BarcodeLib.dll

下载地址 ：http://download.csdn.net/detail/lllooollpp/7961715

UPC-A

UPC-E

UPC 2 Digit Ext.

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：
