Unzip files

Hello,

After a few researches i found this to zip files :https://help.syncfusion.com/aspnetmvc-classic/xlsio/faq/how-to-zip-files-by-using-the-syncfusion-compression-zip-namespace

But I couldn't find any documentation to unzip files. I use a method to get a byte[] from my database when I clic on a cell from my grid. Now then I have to unzip it in order to return a byte[] of the file (mostly PDF or DOCX) inside.

Could you show me a documentation or sample in order to do that ?

Regards,
David.

Hi,

Thank you for your answer.

Unfortunately, it doesn't completly close my issue. Your samples work for files that are located on the computer and that we know of. I am only working with an array of bytes whether it is to upload or download.

So that means I don't have a path and the file is only known as a byte[].

Today I directly download the zipfile as base64 with a link "a" in javascript (called from a link in the grid) :

data = "data:application/zip;base64," + binary;
var a = window.document.createElement("a");
a.rel='nofollow' href = data;
a.download = filename;
document.body.appendChild(a);
a.click();
document.body.removeChild(a);

But I would like to unzip (with C# or Javascript) the file from my variable byte[]  and return the result (still as a byte[]) to download the file inside with my javascript.

To be very brief :
The user click on the link -> app gets the file as an array of byte from oracle server -> unzip -> return the unzipped file inside as an array of byte -> JS download 

Regards,
David.
