office2010里好像能直接将文件另存为.PDF格式的
 
安装好之后，打开VS,以VS2005为例
新建windows应用程序项目
添加以下com组件的引用
Microsoft Word 12.0 Object Library
Microsoft PowerPoint 12.0 Object Library
Microsoft Excel 12.0 Object Library

using Word = Microsoft.Office.Interop.Word; using Excel = Microsoft.Office.Interop.Excel; using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using Microsoft.Office.Core;
 
我们可以使用一个枚举类型来决定生成文件的类型
Word.WdExportFormat wd = Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF;
Excel.XlFixedFormatType excelType = Microsoft.Office.Interop.Excel.XlFixedFormatType.xlTypePDF; PowerPoint.PpSaveAsFileType ppType = Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPDF;

  • 在组件服务中添加权限
单击开始，单击运行， 然后键入 DCOMCNFG。选择要自动运行的应用程序。应用程序名称如下所示：
Microsoft Access 97 - Microsoft Access 数据库 Microsoft Access 2000/2002 - Microsoft Access 应用程序 Microsoft Excel 97/2000/2002 - Microsoft Excel 应用程序 Microsoft Word 97 - Microsoft Word Basic Microsoft Word 2000/2002 - Microsoft Word 文档
单击属性打开此应用程序的属性对话框。
 

1）标示—运行此应用程序的用户账户—下列用户；然后输入Administrator用户组中的一个用户。

注：更改服务器中组件服务所用到的用户密码时，须在组件中重新输入新的密码，才能正常生成Word。

2）安全—启动和激活权限，选择“自定义”，添加IIS_WPG用户的本地启动、本地激活权限；

3）安全—访问权限，选择“自定义”，添加IIS_WPG用户的本地访问权限；
