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

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;

            }

        }

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); }

 

 

 

 

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

  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>
