• Install-Package Unzip

Usage

using (var unzip = new Unzip("zyan-sources.zip"))
{
	// list all files in the archive
	foreach (var fileName in unzip.FileNames)
	{
		Console.WriteLine(fileName);
	}

	// extract single file to a specified location
	unzip.Extract(@"source\Zyan.Communication\ZyanConnection.cs", "test.cs");

	// extract file to a stream
	unzip.Extract(@"source\Zyan.Communication\ZyanProxy.cs", stream);

	// extract all files from zip archive to a directory
	unzip.ExtractToDirectory(outputDirectory);
}
