PDF/WORD/EXCEL/PPT 文档在线阅读

查资料看了2种解决方法：

1.通过办公软件dll转换，用flans去看

2.通过Aspose转换成pdf格式，在用js前台读pdf（我用的pdf.js）

今天我解决的就是WORD/EXCEL/PPT 转化成 PDF ，然后 PDF在线阅读

1.WORD/PPT/EXCEL转PPT类(很简单的)

private string upFile()
{
int iTotal = Request.Files.Count;

if (iTotal == 0)
{
_msg = "没有数据";
}
else
{
HttpPostedFile file = Request.Files[0];
string path = "file\\" + DateTime.Now.ToString("yyyy-MM-dd") + "\\";
string viewPath = "PDF\\web\\" + path;
string ArticlePath = System.Web.HttpContext.Current.Server.MapPath("~") + viewPath;
if (file.ContentLength > 0 || !string.IsNullOrEmpty(file.FileName))
{
//建立图片主文件夹
if (!Directory.Exists(ArticlePath))
{
Directory.CreateDirectory(ArticlePath);
}
saveName = Path.GetFileName(file.FileName);
string extension = Path.GetExtension(file.FileName).ToLower();
string fileName = DateTime.Now.ToString("HH-mm-ss") + extension;
ArticlePath += fileName;
//保存文件
file.SaveAs(ArticlePath);
string pdfpath = ArticlePath.Substring(0, ArticlePath.Length - extension.Length) + ".pdf";
if (extension == ".doc" || extension == ".docx")
{
office2pdf.DOCConvertToPDF(ArticlePath, pdfpath);
}
else if (extension == ".ppt" || extension == ".pptx")
{
office2pdf.PPTConvertToPDF(ArticlePath, pdfpath);
}
else if (extension == ".xls" || extension == ".xlsx")
{
office2pdf.XLSConvertToPDF(ArticlePath, pdfpath);
}
else if (extension == ".pdf")
{
}
else
{
this.RegisterStartupScript("newWindow", "<script language='javascript'>alert('非法文件！')</script>");
return "";
}
DelFile(ArticlePath);
savePath = path + fileName.Substring(0, fileName.Length - extension.Length) + ".pdf";
return savePath;
}
}
return "";

}
