Hi,

Please tell, is there any existing ZIP library that maybe used in Windows Phone and Windows Store applications?

Thanks.

I use Ionic zip on Windows Phone. On Windows Store you have it in the .NET Framework itself:

Is there source code for “Ionic zip”? Or it is just dll ?

Yeah, it’s open source.

I’m not able to use “ZipArchive” class inside Unity. Please tell me how you fixed this issue?

You can’t use it in Unity project because it targets different version of .net framework. You can use it only in a resulting project generated by Unity for Windows Store and in plugins.

So if you want it in Unity project you have to make some public interface implemented in the generated project or write a plugin.

Thanks a lot!

Seems this is some hack :slight_smile: I think this creates some issues during debug process. Nevertheless, thank you!

I’m still have questions. Please help

In Assets/Plugins folder I’m able to put only .NET Framework 3.5 libraries. ZipArchive needs .Net Framework 4.5 (plase see: ZipArchive Class (System.IO.Compression) | Microsoft Learn)

So, I’m still not able to use ZipArchive in Windows Store application. Please tell me, is there is some solution? Maybe some port between Assets/Plugins and Assets\Plugins\Metro\ libraries.

Thanks

I was wrong then.

Public interface is your only option I guess. I do that all the time. It’s lazy and ugly, but works.

Thanks.

I created plugin for each platform. When it was able, we use native classes to unzip files, otherwise we use “Ionic zip”.

Hi,

How did you make ionic zip works in Windows Phone? It works fine in editor, but I keep getting build errors when trying to build into WP8 project. A alot of : “Error : … doesn’t exists in target framework”.
I’ve tried both Net 2.0 and Net 2.0 Subset.
I’ve also tried using the dotNetZip 1.9.1.8 from the official site (error in build), and also the one modified for Unity
in this link : GitHub - HalfVoxel/DotNetZip: A version of DotNetZip which is more suited for Unity, especially mobile versions (can be compiled, but failed in extracting file, empty extract, no error message was triggered)

I’m using Unity 4.5.3f3
