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;        }    }}
