比较全的一个C#操作word文档示例

最近两天研究了一下如何使用vs2008(c#语言)输出word文档。以下是几点总结：

1、非常简单。

2、开发及运行环境要求。操作系统为：windowsxp(安装.net framework2.0)/vista/win7；在操作系统必须安装word2003完全安装版。这里必须要强调是word2003完全安装版，因为软件开发及运行都需要一个com组件:microsoft word 11.0 object library。如果不是word2003完全安装版，可以下载这个com组件，并手动的安装这个com组件。下载地址为：，文件不大，只有4m左右。

3、c#工程设置。这里的工程设置，就是添加com组件。步骤为：在工程资源管理器中"添加引用"->"com"选项卡->在下拉列表中选microsoft word 11.0 object library。ok了，看上去，跟添加一般的dll一样,但实际上vs2008在这个过程中完成一系列复杂的关于.net调用com组件的操作，不过，幸好我们不用管这个。

4、接下就是写代码了。在这里，使用word的com对像，跟使用一般的非com对像一样，非常流畅，好像根本就不管它什么com不com的。为了使代码比较简洁，可以在源代码文件顶添加这样的一条语句：using word = microsoft.office.interop.word;

5、最好是对word对像模型有一定的了解，这样在写代码的时候就不会那么“迷茫”了。wore对像模型中有几个比较重要的对像，它们是application、document、selection、range、bookmark，以及其它的一些对像,如:paragraph、section、table等级。刚开始学的时候，感觉selection、range、bookmark这几个对像有点迷惑人，selection可能好理解，就是表示当前的选择区域，如果没有选择就表示光标所在位置。range和bookmark，其实在很多地方很像，不过也有一些区别，在这里就不多说了，google一下"word.range"就行了。

6、在写代码的过程中，经常会想要实现的一些操作，但是由于对word对像不熟悉而不知怎么用代码实现。比如设置页眉、添加页码什么的，如果在word程序里手动的操作当然很简单，但是要用代码来实现，对初学者来说就可能不那么容易了。遇到这种情况，一般有两种方法可以选择：一种是"百度/google法"，别一种，也是我所推荐的一种就是，利用word的“录制宏”功能把想要实现的操作录成宏之后，再看宏里的代码，宏里的代码其实几乎就是你想要的代码了（只不过语法有一点不一样而已）。

7、以下给出一个示例，这个示例里面包括了一些常用的图、文、表、公式的编辑与排版以及页面设置、页眉、页码的操作，里面都有注释，写得很清楚。
