今天小编就为大家分享一篇关于C#将PPT文件转换成PDF文件,小编觉得内容挺不错的,现在分享给大家,具有很好的参考价值,需要的朋友一起跟随小编来看看吧
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;
}
}
}
