C# - Extract Zip with file listing

Question

I would like to extract a pre-set zip file WITHOUT an external library to a given folder, and I would like to inform the user about the current percent of extraction (with a simple progressBar and a percent label) and the currently extracted file. Is this possible somehow?

It is important to do not use any other library.

(For updating all the labels and progressBar, I use a separate backgroundWorker)

Answer 1

You can use System.IO.Compression.GZipStream to extract the file. This post discusses how to compute and display to progress: http://stackoverflow.com/questions/412785/computing-progress-bar-using-gzipstream

EDIT: The comment below is correct. I thought for sure that I'd read that the GZipStream class worked with ZIP files but it's clear I was mistaken.

Answer 3

See this topic from Ultimate Zip: Unzipping files and folders. You may need to handle the Zip's Progress event to show progress information.
