Zip and Download file in asp.net

Question

5.00/5 (1 vote)

See more:

I have a folder that is created by some service.
It contains multiple sub-folders.
I want to give the provision to the users of a website to download the entire folder as a single zip file without needing to create and store the zip file in the system.
That is create a temporary zip file and push it to the user.

Thanks in advance.

I believe this article will give you exactly what you are looking for: http://www.4guysfromrolla.com/articles/092910-1.aspx[^]

Right now I believe you still have to use that third party library but in .NET 4.5, you can do this without a library because it is built in. I did an article on zip files in .NET 4.5 recently, although I didn't discuss the web side of things. It might be of use to you in your planning, depending on if you want to use the latest version of .NET or not. Here is a link to the article, in case you are interested: Creating Zip Files Easily in .NET 4.5[^]

Sounds rude!

You can just add the root folder and all the folders underneath will be added (or each root folder if there are multiple in the root directory). There is documentation on how to add a folder, but here is a quick example I found: http://c-madeeasy.blogspot.com/2011/10/using-dotnetzip-to-compress-all-files.html

Hi.
You might look forward to SharpZipLib i think with help of this library you could compress entire folder with subfolders and files.
Good luck.
