PDFSharp生成PDF.

在上面用OpenXML生成word后,原来利用Word2010里的导出成PDF功能就不能用.

然后找开源组件生成PDF,最开始用的是iTextSharp,做完导出报表了才发现,这个开源协议用的是AGPL,只能放弃,重新查找后,找到PDFSharp(MTI协议).结合了MigraDoc来生成PDF,过程大同小异,对比iTextSharp,在画相关元素时,会慢不少,20页A4内容,OpenXML和iTextSharp都能保持在2S内输出完成,而PDFSharp需要5-10S,不知是不是因为GDI+的原因.

代码不讲解了,只贴出来,只说明一点,对中文的支持,需要设置下.

总的来说,和OpenXML一样,在用OpenXML导出数据时,已经把数据整理为,输出数据,输出图形,输出表格,输出一组数据.这几种形式,我用PDFSharp时,只是针对这几个类型进行处理一下就行了.

毕竟OpenXML只能导出word2007及以上识别的文件,word2003还是需要Ms office com组件,这个类我就不贴了,搜索出word文章几乎都用的这种.
