C# 利用BarcodeLib.dll生成条形码

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。 

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); }
