	Hi!

	We try to uncompress a zip file from a streaming source like so:

	[code lang='c#']public void Unzip (Stream stream)

	{

	    var zip = new ComponentPro.Compression.Zip();

	    zip.Open(stream, false);

	   

	    // list all files

	    foreach (var entry in zip.ListAll())

	    {

	        // if entry ends in zip

	        if (entry.Name.EndsWith(".zip"))

	            Unzip(entry.OpenRead(FileShare.Read));

	    }

	 

	    zip.Close();

	}

	[/code]

	 

	However, reading the nested zip file using OpenRead() does not work (results in ComponentPro.IO.FileSystemNotSupportedException : The 'OpenRead' operation is not supported.) How to read a nested zip file from a stream?

	 

	We are currently evaluating your library and are thinking about buying it. This evaluation is timeboxed, so a quick answer would really help me to decide if we are going to buy your library or a library from another vendor.

	 

	Best regards,

	D.R.
