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

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;
                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); }
