在线预览word、excel、ppt利用aspose动态生成html

主要代码

private bool OfficeDocumentToHtml(string sourceDoc, string saveDoc){    bool result = false;    //获取文件扩展名    string docExtendName = System.IO.Path.GetExtension(sourceDoc).ToLower();    switch (docExtendName)    {        case ".doc":        case ".docx":            Aspose.Words.Document doc = new Aspose.Words.Document(sourceDoc);            doc.Save(saveDoc, Aspose.Words.SaveFormat.Html);            result = true;            break;        case ".xls":        case ".xlsx":            Workbook workbook = new Workbook(sourceDoc);            workbook.Save(saveDoc, SaveFormat.Html);            result = true;            break;        case ".ppt":        case ".pptx":            //templateFile = templateFile.Replace("/", "\\");            //string templateFile = sourceDoc;            //templateFile = templateFile.Replace("/", "\\");            PresentationEx pres = new PresentationEx(sourceDoc);            pres.Save(saveDoc, Aspose.Slides.Export.SaveFormat.Html);            result = true;            break;        default:            break;    }    return result;}

在线预览pdf利用pdfobject.js生成(aspose也可以做到，但效果不理想)

主要代码

private bool PdfToHtml(string fileName, string tempFile, string saveDoc){    //---------------------读html模板页面到stringbuilder对象里----     StringBuilder htmltext = new StringBuilder();    using (StreamReader sr = new StreamReader(tempFile)) //模板页路径     {        String line;        while ((line = sr.ReadLine()) != null)        {            htmltext.Append(line);        }        sr.Close();    }    fileName = fileName.Replace("\\", "/");    //----------替换htm里的标记为你想加的内容     htmltext.Replace("$PDFFILEPATH", fileName);    //----------生成htm文件------------------――     using (StreamWriter sw = new StreamWriter(saveDoc, false,        System.Text.Encoding.GetEncoding("utf-8"))) //保存地址    {        sw.WriteLine(htmltext);        sw.Flush();        sw.Close();    }    return true;}
