/// 官方网站:http://www.websupergoo.com/
/// demo用的是当前的最新版本ABCpdf .NET 9.1 X64,支持当前windows的主流操作系统,包括最新的win8,IE10(服务器版本)
/// ABCpdf有30天的试用期
/// 引用方式,安装ABCpdf组件,有两个DLL是有用的,需要对ABCpdf.dll添加引用,ABCpdf9-64.dll(引擎组件)放在bin目录下就可以了
/// 它有其他组件比如(iTextSharp)所不具备的功能,如能直接指定一个URL就可以将页面转换为PDF,这也是它的强大之处托福答案 www.jx-jf.com
/// 在选择版本时要注意,区分64位和32位,如果版本放错了,会发生错误,在IIS的部署上一定要注意,这里很可能会出现问题,请参考官方资料
/// 地址:http://www.websupergoo.com/support.htm 常见问题介绍的比较详细
