Hello,

I'm beginner in ASP.net MVC4. And I'm trying to display the content of the word and excel file in my web page. I wrote this function in the HomeController , but it didn't display the content. it only downloaded the file. how can I preview the file in my webpage? Thanks

C#

[HttpGet] public FileResult downloadFile() { 
byte[] fileBytes = System.IO.File.ReadAllBytes("J:\asp.net\ViewInformation\ViewInformation\Content\book.xlsx);
 return File(fileBytes, ,application/vnd.ms-excel, 'book.xlsx'); }

Yes, you can display the content, but it would be totally pointless. The file is actually the ZIPed set of some XML file, according to the Microsoft's Open XML standard: https://en.wikipedia.org/wiki/Office_Open_XML[^].

One way of reading the file in semantically sensible way would be using Microsoft Open XML SDK. Please see this CodeProject article: Creating basic Excel workbook with Open XML[^].
