Hi experts,
I use AX 2012.
I want to extract files from a zip file archive. I have been told to do this:
System.IO.Compression.ZipFile::ExtractToDirectory(filePath, myZipFileName);
When I enter that into AX 2012, it says that "ZipFile" is not a class. (And when I write "System.IO.Compression.", I can also see that "ZipFile" is not on the list of options after "Compression".
What must I do to make this work?
Is there another way to do this?
Hope you can help.
Hi Martin,
Now I have added a reference to "System.IO.Compression.FileSystem" and removed my reference to "System.IO.Compression.ZipFile".
Now it works fine.
Thank you very much!
According to ZipFile documentation, you need System.IO.Compression.FileSystem.dll as well. Adding it sounds like a good next step.
Also, pay attentions to versions. I can't say whether you should use a different version without knowing which version you're referencing at the moment.
I don't have the DLL file. I just made the reference without pointing to any file. "System.IO.Compression.ZipFile" is on the long list called "Add reference". I guess that is the list of what is in the GAC plus what might have been added.
Can I update the GAC or should I install a new version of .NET or how do I get, what I am missing?
Where did you find the DLL? What is its version?
Just adding the reference isn't sufficient if the process (such as AX client) can't load the file at runtime. If it's not in Global Assembly Cache (GAC), you'll need to put it to bin folder of AX client and possbly the bin folder of AOS (if you want to run the code on server). If it's in GAC, you don't have to do that - it would mean that your problem is caused by something else.
Hi Martin,
Thank you for your reply.
No, I did not. (Working with dll files is new to me.)
Now I have added a new reference in the AOT. In the list, "Add reference", I found "System.IO.Compression.ZipFile" and pressed "Select" and "OK".
If I in the list, "Add reference" press "Browse", I can see the files in "C:\Program Files (x86)\Microsoft Dynamics AX\60\Client\Bin". There are no files called "System.IO...".
I have compiled, left AX and entered AX again. I still get the compilation error.
Do you have a reference to System.IO.Compression.ZipFile.dll?
