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

然后项目中添加引用
[csharp] view plaincopy
1. private void button6_Click(object sender, EventArgs e)
2. {
3. System.Drawing.Image image;
4. int width = 148, height = 55;

6. if (File.Exists(fileSavePath))
7. File.Delete(fileSavePath);
8. GetBarcode(height, width, BarcodeLib.TYPE.CODE128, "20131025-136", out image, fileSavePath);
10. pictureBox1.Image = Image.FromFile("BarcodePattern.jpg");
11. }
12. public static void GetBarcode(int height, int width, BarcodeLib.TYPE type, string code, out System.Drawing.Image image, string fileSaveUrl)
13. {
14. try
15. {
16. image = null;
17. BarcodeLib.Barcode b = new BarcodeLib.Barcode();
18. b.BackColor = System.Drawing.Color.White;//图片背景颜色
19. b.ForeColor = System.Drawing.Color.Black;//条码颜色
20. b.IncludeLabel = true;
21. b.Alignment = BarcodeLib.AlignmentPositions.LEFT;
22. b.LabelPosition = BarcodeLib.LabelPositions.BOTTOMCENTER;
23. b.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;//图片格式
24. System.Drawing.Font font = new System.Drawing.Font("verdana", 10f);//字体设置
25. b.LabelFont = font;
26. b.Height = height;//图片高度设置(px单位)
27. b.Width = width;//图片宽度设置(px单位)
29. image = b.Encode(type, code);//生成图片

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
