前言

　　本文所使用的二维码生成代码是谷歌开源的条形码图像处理库完成的，c#版的代码可去https://code.google.com/p/zxing/downloads/list下载压缩包。

　　截止目前为止最新版本为2.2，提供以下编码格式的支持：

UPC-A and UPC-E
EAN-8 and EAN-13
Code 39
Code 93
Code 128
QR Code
ITF
Codabar
RSS-14 (all variants)
Data Matrix
PDF 417 ('alpha' quality)
Aztec ('alpha' quality)

　同时官网提供了 Android、cpp、C#、iPhone、j2me、j2se、jruby、objc、rim、symbian等多种应用的类库，具体详情可以参考下载的源码包中。

　　本文已经下载好了，c#版的zxing代码，并编译生成了类库，供程序直接调用。

软件截图及说明

功能说明：1、根据文字输入及时生成二维码，支持保存，打印

　　　　　2、支持解码，打开二维码文件解码

　　　　　3、采用IrisSkin4皮肤美化

代码说明

　　打印代码。
关键代码在txtContent_TextChanged()及打开方法中处理了。
最后说明：程序比较简单，不做过多说明，时间仓促代码存在很多不合理的地方，欢迎拍砖。
