使用第三方插件 Office 实现转换

1.Application方式转换

/// <summary>/// Microsoft.Office.Interop.PowerPoint/// 使用第三方软件 office/// </summary>/// <param name="pptPath">需要转换的ppt文件路径</param>/// <param name="pdfPath">转换后的路径</param>public static void OfferPptToPdf(string pptPath, string pdfPath){try{pdfPath=pdfPath.Replace('/', '\\');//创建对象 并且打开ppt文件Microsoft.Office.Interop.PowerPoint.Application pptApplication = new Microsoft.Office.Interop.PowerPoint.Application();Microsoft.Office.Interop.PowerPoint.Presentation pptPresentation = pptApplication.Presentations.Open(pptPath, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse);//if (!File.Exists(newfilePath))//不存在//{//ppt文件 保存为pdf文件pptPresentation.SaveAs(pdfPath, Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPDF, Microsoft.Office.Core.MsoTriState.msoFalse);//}//关闭对象pptPresentation.Close();}catch (Exception ex){throw;}}

2.ApplicationClass方式转换

/// <summary>/// Microsoft.Office.Interop.PowerPoint/// 把PowerPoing文件转换成PDF格式文件/// </summary>/// <param name="pptPath">源文件路径</param>/// <param name="pdfPath">目标文件路径</param>/// <returns>true=转换成功</returns>public static bool PPTConvertToPDF(string pptPath, string pdfPath){bool result;pdfPath = pdfPath.Replace('/', '\\');Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType targetFileType = Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPDF;object missing = Type.Missing;Microsoft.Office.Interop.PowerPoint.ApplicationClass application = null;Microsoft.Office.Interop.PowerPoint.Presentation persentation = null;try{application = new Microsoft.Office.Interop.PowerPoint.ApplicationClass();persentation = application.Presentations.Open(pptPath, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse);persentation.SaveAs(pdfPath, targetFileType, Microsoft.Office.Core.MsoTriState.msoTrue);result = true;}catch (Exception ex){result = false;}finally{if (persentation != null){persentation.Close();persentation = null;}if (application != null){application.Quit();application = null;}GC.Collect();GC.WaitForPendingFinalizers();GC.Collect();GC.WaitForPendingFinalizers();}return result;}

使用第三方插件 Spire.Presentation 实现转换

/// <summary>/// Spire.Presentation 正版需要付费/// </summary>/// <param name="pptPath"></param>/// <param name="pdfPath"></param>public static void pptToPdf(string pptPath, string pdfPath){Spire.Presentation.Presentation presentation = new Spire.Presentation.Presentation();presentation.LoadFromFile(pptPath);presentation.SaveToFile(pdfPath, Spire.Presentation.FileFormat.PDF);}

使用第三方插件 Aspose.Slides 实现转换
