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;
usingSystem; usingSystem.Collections.Generic; usingSystem.IO; usingSystem.Linq; usingSystem.Text; usingSystem.Runtime.InteropServices; usingMicrosoft.Office.Interop.PowerPoint; //Office命名空间 namespaceOfficeToPdf { //excel类 classPowerPointConverter { //构造函数 publicPowerPointConverter() {} //////转换PowerPoint成PDF文档 /// ///原文件路径 /// pdf文件输出路径 /// true成功 publicboolConverterToPdf(string_lstrInputFile,string_lstrOutFile) { Microsoft.Office.Interop.PowerPoint.ApplicationlobjPowerPointApp=null; Microsoft.Office.Interop.PowerPoint.Presentationlobjppt=null; objectlobjMissing=System.Reflection.Missing.Value; objectlobjSaveChanges=null; try { lobjPowerPointApp=newMicrosoft.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(Exceptionex) { //其他日志操作; returnfalse; } 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(); } returntrue; } } }
