What is the default System.IO.Compression.ZipFile CompressionLevel value?

Question

I'm making a zip file using

ZipFile.CreateFromDirectory(DeployDirectory, ZipDirectory + @"\DatabaseDeploy.zip", CompressionLevel.Fastest, true);

I want to include the base directory so I need the overload that takes a CompressionLevel value as third argument. But I don't care about that, I just want it to work the same way as for the overload that just takes string, string.

Anyone knows?

Answer 1

CompressionLevel.Optimal, for now at least. You could also probably set the argument to null to get the default behavior, even if it changes in the future.
