【转】【OpenXML】OpenXML操作word

OpenXML概述

项目中经常需要操作word，之前的方式是采用COM接口，这个接口很不稳定，经常报错。现在开始采用OpenXML。OpenXML（OOXML）是微软在Office 2007中提出的一种新的文档格式，Office 2007中的Word、Excel、PowerPoint默认均采用OpenXML格式 。
OpenXml相对于用MS提供的COM组件来生成WORD,有如下优势:

1.相对于MS 的COM组件,因为版本带来的不兼容问题,及各种会生成WORD半途会崩溃的问题.
2.对比填满一张30多页的WORD来说(包含图,表等),用COM组件来生成会占用20秒,Openxml1秒.
3.MS Word软件太贵了,你的客户装的是开源WORD,如LibreOffice,OpenOffice.这样你就只能用Openxml生成的WORD文档,各种支持MS Word都能打开,避免客户机器上安装MS Word.
4.代码简单。用OpenXML开发word简直太方便了！！！

要做OpenXML的开发，需要了解OpenXML的基本结构。

Open XML SDK 2.0 tool

因为OpenXML的结构比较复杂，开始开发时往往不好入门，摸不清其结构。微软很贴心的提供了一个工具，Open XML SDK Productivity Tool for Microsoft Office。
下载地址  百度云：OpenXMLSDKTool 提取码: u6q8  OpenXMLSDK  提取码: k873
这个工具可以打开任意一个docx的文档，然后Reflect Code，得到整个文档代码，之后怎么操作直接看代码就好了，真是太方便了。

另外这个工具也提供了文档，不清楚的可以查一下文档。

代码示例

我参考上面的工具，写了一个简单的操作word的帮助类。
