C#生成Code39(extend)条形码实例
Code39是条形码的一种。由于编制简单、能够对任意长度的数据进行编码、支持设备广泛等特性而被广泛采用。
能够对任意长度的数据进行编码。其局限在于印刷品的长度和条码阅读器的识别范围。
支持设备广泛。目前几乎所有的条形码阅读设备都能阅读Code39码，打印机也是同样情况。
编制简单。简单的开发技术就能快速生成相应的编码图像。
一般Code39码由5条线和分开它们的4条缝隙共9个元素构成。线和缝隙有宽窄之分，而且无论线还是缝隙仅有3个比其他的元素要宽一定比例。39码因此得名
Code39条形码规则
1、 每五条线表示一个字符；
2、 粗线表示1，细线表示0；
3、 线条间的间隙宽的表示1，窄的表示0；
4、 五条线加上它们之间的四条间隙就是九位二进制编码，而且这九位中必定有三位是1，所以称为39码；
5、 条形码的首尾各一个 * 标识开始和结束。
Code 39只接受如下43个有效输入字符：
1、26个大写字母（A - Z），
2、十个数字（0 - 9），
3、连接号(-),句号（.）,空格,美圆符号($),斜扛(/),加号(+)以及百分号(%)。
4、其余的输入将被忽略。
5、code39通常情况下不需要校验码。但是对於精确度要求高的应用，需要在code39条形码後面增加一个校验码。
条形码的生成网上也有很多库文件，做的特别好的都是商业授权。一维码二维码在.net开源项目中的生成读取比较知名的有:Zxing.net(http://zxingnet.*c*odep*lex.com/)、BarcodeLib等
但有些时候开源软件所实现的并不满足当下的需求，所以还要做一些其他尝试。效果如下图：

这个方法是根据DPI以及数据模块的高宽来确定条码的实际高宽。模块的宽度以毫米（mm）来算。类中的getBitmapImage方法的一个参数getBitmapImage为DPI。安卓用户安装平时常用的扫码软件即可做识别测试。就识别率来说还是可以的，扫描枪绝对是可以扫的出的。同时使用过MessagingToolkit.Barcode进行解码测试，万张无一误读。
C#生成code128条形码实例
CODE128条形码是广泛应用在企业内部管理、生产流程、物流控制系统方面的条码码制，由于其优良的特性在管理信息系统的设计中被广泛使用，CODE128码是应用最广泛的条码码制之一。
CODE128条形码是1981年引入的一种高密度条码，CODE128 码可表示从 ASCII 0 到ASCII 127 共128个字符，故称128码。其中包含了数字、字母和符号字符。
