C#生成Code39条形码【非条形码字体】

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。

1. 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。
2. 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。
3. 编制简单。简单的开发技术就能快速生成相应的编码图像。
4. 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。

%26nbsp;

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(%)。
%26nbsp; %26nbsp; 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.codeplex.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：
