用.net操作word

要操作Word,我们就需要Word的对象库文件“MSWORD.OLB”( word 2000为MSWORD9.OLB ),通常安装了Office Word后,你就可以在office安装目录的Office10文件夹下面找到这个文件,当我们将这个文件引入到项目后,我们就可以在源码中使用各种操作函数来操作Word.具体做法是打开菜单栏中的项目>添加引用>浏览,在打开的“选择组件”对话框中找到MSWORD.OLB后按确定即可引入此对象库文件,vs.net将会自动将 库文件转化为DLL组件,这样我们只要在源码中创建该组件对象即可达到操作Word的目的！
     在CS代码文件中对命名空间的应用,如：using Word;范例如下：
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using Word;
