How to uncompress zip file into a folder without external dependencies like Interop.Shell32.dll or 3rd-Party Assemblies?
-
Hi, i am looking for a way to extract the entire content of a zip file into a folder without using any external dependencies like Interop.Shell32.dll or 3rd-Party Libs like DotNetZip etc. The entire thing should run from within a single assembly. I personally would like to use the Windows build-in ZIP-Shell extension available from windows XP to Win10 by accessing it with preferably late binding via .NET/C#, but i am kinda stuck on how to do it and what the COM-Interfaces/Types for that should look like. :confused: Any help would be really higly appreciated. :thumbsup: best K.

Zipping using System.IO.Compression[^]

Hi Eddy, thanks for the answer. I forgot one thing to mention here, that the application is using the 2.0 .NET Framework and cant compiled against anything else for compatibility use with other libraries/references included. The System.IO.Compression needs at least 4.5 Framework. best K.

It doesn't; it is part of 2.0. See MSDN[^].

This is true in terms of availability of the namespace, but the unzipping zip file classes are available starting 4.5 FW. See for yourself: ZipFile Class (System.IO.Compression)[^]

You are referring to a helper-class that simplifies the tasks. The GZipStream is available in 2.0, and you could zip/unzip in 2.0 without using third-party libraries. Example on MSDN[^].

I am not sure how this will help me to unpack a zip file into a folder. The example there only shows how to compress/decompress a single file with GZip compression. I am familiar with that mechanism and it would be overkill to reinvent a library from Deflate/GZip classes in .NET to create a unpacker for folders packet into a zip container file. The example works just fine on a single file, but not on a Zip archive.

Then use one of the existing libraries. Did you not state you did not want a dependency on things like SharpZipLib and DotNetZip?

Yes, i did and thats why i was prefering the late binding option to the shell zip functionality build into windows. As said, the entire thing should be running from a single exe file with no extra libs attached. the zip com extension is available from XP up to 10. using the GZip/Deflate classes in that namespace supporting .NET 2.0 would require to implement a full unzipper for zip containers in zip format like implemented in the helper classes available starting 4.5 FW. that would be a total overkill.

Hi Richard, thanks for the answer. Yes, i have seen that article before, but this uses early binding with a com wrapper. Thats the easy way, but i am looking for late binding at runtime with no additionall assembly file, like this project uses. best K.
