C# 生产成条形码3种方法
首先效果:

1:首先下载BarcodeLib.dll 下载地址 http://pan.baidu.com/share/link?shareid=2590968386&uk=2148890391&fid=1692834292 如果不存在了则自行搜索下载。
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;
- 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。
