ppt转换PDF失败，pptx可以转换成功·····部分代码如下

                case "PPT":
                case "PPTX":
                    try
                    {
                        Aspose.Slides.Presentation ppt = new Aspose.Slides.Presentation(p);
                        ppt.Save(fn, Aspose.Slides.Export.SaveFormat.Pdf);
                       
                    }
                    catch (Exception)
                    {
                        return -1;
                    }
                    break;
