Compress a Directory in net 4.0? No DLL's? - Pim Fortuyn - Dec 11, 2016
How would i compress a directory into a .zip or .gz without any external dll's?
I can do it with with dotnetzip but then you have an external dll which i would like to avoid.
I know in net 4.5 you can use this: https://msdn.microsoft.com/en-us/library/system.io.compression.zipfile(v=vs.110).aspx
But I need a solution for 4.0

DotNetZip:

Standalone .EXE file (even in 4.0)

You could implement LZMA compression via 7-zip's SDK for C#. http://7-zip.org/sdk.html

Doesn't seem to work when building the solution using xbuild (linux)

.NET 4 you probably have to use gzipstream if you dont want third party libs

It can only compress single files. I would like to compress a folder/directory.

Are there any easier alternatives? seems quite complicated 🤮
Actually I found this which seems to work nicely:
Code
public static void zipFolder(string inputFolder, string outputZip)
{
using (Package Zip = Package.Open(outputZip, FileMode.Create))
{
foreach (string F in Directory.GetFiles(inputFolder, "*.*", SearchOption.AllDirectories))
{
string F1 = F.Replace(' ', '_');
Uri URI = new Uri(F1.Substring(inputFolder.Length), UriKind.Relative);
PackagePart ZipPart = Zip.CreatePart(PackUriHelper.CreatePartUri(URI), MediaTypeNames.Application.Zip, CompressionOption.Maximum);
byte[] B = File.ReadAllBytes(F);
ZipPart.GetStream().Write(B, 0, B.Length);
}
}
}
