这是一个微软官方出的office插件。

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;
