　　对于比较大（如大于5M）的pdf文档一般都有数百页的内容了，对于这样的“大”文档一次性转换成HTML文档相对比较慢，所以我们通常会考虑到按指定页来转换，根据页码转换需要的哪一页，这样转换非常快，而且可以随意指定要查看那一页:

(fileInfo.Extension == ) 2 { 3 if (pageIndex == 0 && fileInfo.Length / 1024 / 1024 < 2) 4 { 5 var pdfDocument = new Aspose.Pdf.Document(filePath); 6 pdfDocument.Save(generateFilePath, Aspose.Pdf.SaveFormat.Html); 7 } (pageIndex == 0) 9 { 10 pageIndex++; 11 pageView = true; 12 var pdfDocument = new Aspose.Pdf.Document(filePath); 13 Aspose.Pdf.Document newDocument = new Aspose.Pdf.Document(); 14 newDocument.Pages.Add(pdfDocument.Pages[pageIndex]); 15 newDocument.Save(generateFilePath, Aspose.Pdf.SaveFormat.Html); 16 17 } (pageIndex == -1) 19 { 20 pageView = true; 21 var pdfDocument = new Aspose.Pdf.Document(filePath); 22 Aspose.Pdf.Document newDocument = new Aspose.Pdf.Document(); 23 newDocument.Pages.Add(pdfDocument.Pages[pdfDocument.Pages.Count]); 24 newDocument.Save(generateFilePath, Aspose.Pdf.SaveFormat.Html); 25 pageIndex = pdfDocument.Pages.Count; 26 } { 29 pageView = true; 30 var pdfDocument = new Aspose.Pdf.Document(filePath); 31 if (pageIndex > 0 && pageIndex < pdfDocument.Pages.Count) 32 { 33 Aspose.Pdf.Document newDocument = new Aspose.Pdf.Document(); 34 newDocument.Pages.Add(pdfDocument.Pages[pageIndex]); 35 newDocument.Save(generateFilePath, Aspose.Pdf.SaveFormat.Html); 36 } { 39 Aspose.Pdf.Document newDocument = new Aspose.Pdf.Document(); 40 newDocument.Pages.Add(pdfDocument.Pages[pdfDocument.Pages.Count]); 41 newDocument.Save(generateFilePath, Aspose.Pdf.SaveFormat.Html); 42 pageIndex = pdfDocument.Pages.Count; 43 } 44 } 45 viewUrl = webPath;
