C#将PPT文件转换成PDF文件

这里在提供C#代码,将PPT转成PDF.直接上代码;

要引入Microsoft.Office.Interop.PowerPoint; 版本12.0.0.0;

?

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Text;

using System.Runtime.InteropServices;

using Microsoft.Office.Interop.PowerPoint;

//Office 命名空间

namespace OfficeToPdf

{

   //excel 类

   class PowerPointConverter

   {

     //构造函数

     public PowerPointConverter()

     { }

     /// <summary>

     /// 转换PowerPoint 成PDF文档

     /// </summary>

     /// <param name="_lstrInputFile">原文件路径</param>

     /// <param name="_lstrOutFile">pdf文件输出路径</param>

     /// <returns>true 成功</returns>

     public bool ConverterToPdf( string _lstrInputFile, string _lstrOutFile)

     {

       Microsoft.Office.Interop.PowerPoint.Application lobjPowerPointApp = null ;

       Microsoft.Office.Interop.PowerPoint.Presentation lobjppt = null ;

       object lobjMissing = System.Reflection.Missing.Value;

       object lobjSaveChanges = null ;

       try

       {

         lobjPowerPointApp = new Microsoft.Office.Interop.PowerPoint.Application();

         lobjppt = lobjPowerPointApp.Presentations.Open(_lstrInputFile, MSCore.MsoTriState.msoTrue, MSCore.MsoTriState.msoFalse, MSCore.MsoTriState.msoFalse);

         lobjppt.SaveAs(_lstrOutFile, PpSaveAsFileType.ppSaveAsPDF, MSCore.MsoTriState.msoCTrue);      

       }

       catch (Exception ex)

       {

         //其他日志操作;

         return false ;

       }

       finally

       {

         if (lobjppt != null )

         {

           lobjppt.Close();

           Marshal.ReleaseComObject(lobjppt);

           lobjppt = null ;

         }

         if (lobjPowerPointApp != null )

         {

           lobjPowerPointApp.Quit();

           Marshal.ReleaseComObject(lobjPowerPointApp);

           lobjPowerPointApp = null ;

         }

         //主动激活垃圾回收器,主要是避免超大批量转文档时,内存占用过多,而垃圾回收器并不是时刻都在运行!

         GC.Collect();

         GC.WaitForPendingFinalizers();

       }

       return true ;

     }

   }

}
