Using SharpCompress in Unity

An article by mgear    No Comments

If you need to work with zip/rar/tar/gzip packages, can use SharpCompress to handle opening or creating those files.

Compile SharpCompress DLL (unless you can find it online somewhere)

• Download project https://github.com/adamhathcock/sharpcompress
• Unzip and open in VisualStudio (i used 2017)
• Security warning, press ok
• Security warning, press ok
• View / Solution Explorer .. (if not already visible)
• Right click over SharpCompress, select Build
• Now you should have the dll in ..\sharpcompress-master\sharpcompress-master\src\SharpCompress\bin\Debug\ folder (3.5 and 4.5 versions, pick which one you like, recent unity versions support 4.5 by default, so lets pick “net45\SharpCompress.dll”)
• Copy it to your unity project, under Assets\Plugins\SharpCompress\ SharpCompress.dll
• If you are using Unity 2017.x or lower, go to Player Settings / Other settings, and enable 4.6 from “Scripting Runtime Version”
• Test creating zip package with the script below (adjust source and output folders in the script)

TroubleShooting

Error in Android build:
“NotSupportedException: ..il2cpp\libil2cpp\icalls\mscorlib\System.Reflection.Emit\DynamicMethod.cpp(19) : Unsupported internal call for IL2CPP:DynamicMethod::create_dynamic_method – System.Reflection.Emit is not supported.
05-12 01:52:09.319 2523 2549 E Unity : at System.Reflection.Emit.DynamicMethod.CreateDynMethod ()”

Solution:
Use Mono as Scripting Backend (IL2CPP gives that error)
