Hello Forum !

Hello everyone here!

I hope I will enjoy using the forum!

OK my first post is a VB.NET request since I am confused at here.

I just found a code snippet in MSDN which convert an input file to an output (ZIP GZ) file.

It should be OK but I cannot figure it so it can accept multiple files as input and give me one single ZIP GZ output!

Maybe a pro can help me!

Dim SourceFile As FileStream = File.OpenRead(InPath)
Dim DestinationFile As FileStream = File.Create(OutPath)
Dim Buffer(SourceFile.Length) As Byte
SourceFile.Read(Buffer, 0, Buffer.Length)
Using Output As New GZipStream(DestinationFile, CompressionMode.Compress)
       Output.Write(Buffer, 0, Buffer.Length)
End Using
SourceFile.Close()
DestinationFile.Close()

Are you wanting to create a zip file from code? i.e. A typical zip archive containing multiple files each of which can be extracted individually or just concatenate multiple files into one large single compressed block?

I just want to add some files to a single output file for my personal use, I will use it for backup/restore of some of my application files!

IIRC the .Net built in support doesn't really give you the ability to store multiple separate files easily. You might want to look at http://www.icsharpcode.net/OpenSource/SharpZipLib/Download.aspx as they have a free zip library that makes it reasonably easy to do what you want.
