這是一個微軟官方出的office插件。

office2010里好像能直接將文件另存為.PDF格式的

 

安裝好之后，打開VS,以VS2005為例

新建windows應用程序項目

添加以下com組件的引用

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;

 

我們可以使用一個枚舉類型來決定生成文件的類型

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;
