2.ApplicationClass方式转换

            Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType targetFileType = Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPDF;
            object missing = Type.Missing;
            Microsoft.Office.Interop.PowerPoint.ApplicationClass application = null;

                result = true;
            }
            catch (Exception ex)
            {
                result = false;
            }
            finally
            {
                if (persentation != null)
                {

使用第三方插件 Spire.Presentation 实现转换

        /// <summary>

            presentation.LoadFromFile(pptPath);
            presentation.SaveToFile(pdfPath, Spire.Presentation.FileFormat.PDF);
        }

使用第三方插件 Aspose.Slides 实现转换
