unzip using SharpZipLib

[Aji Mathews via .NET 247]

Hi

I am using SharpZipLib. Could someone help with some sample code to unzip a file to a specified location.

Thanks

Re: unzip using SharpZipLib


This uses the ZipInputStream method which provides sequential access
to each entry. The ZipFile method provides random access to each
entry.

The help files have lots of good examples too. They're C# but the
code is very similar to VB.NET.

Note that this was just test code I put together to verify the
decryption functionality since some people reported problems. This is
not really production quality in that it doesn't use try/finally to
ensure all of the streams are properly closed.

HTH,

Sam


Imports System.IO
Imports ICSharpCode.Sha rpZipLib.Zip

Module Module1

Sub Main()
Dim fileName As String = Path.GetFullPat h("../AcapCopy.zip")
Dim destPath As String = Path.GetFullPat h("../Unzipped/")

If Not Directory.Exist s(destPath) Then
Directory.Creat eDirectory(dest Path)
Else
For Each s As String In Directory.GetFi les(destPath)
File.Delete(s)
Next
End If

Dim inStream As New ZipInputStream( File.OpenRead(f ileName))
Dim outStream As FileStream

Dim entry As ZipEntry
Dim buff(2047) As Byte
Dim bytes As Integer

Do While True
entry = inStream.GetNex tEntry()

If entry Is Nothing Then
Exit Do
End If

outStream = File.Create(des tPath + entry.Name, 2048)

Do While True
bytes = inStream.Read(b uff, 0, 2048)
If bytes = 0 Then
Exit Do
End If

outStream.Write (buff, 0, bytes)
Loop

outStream.Close ()
Loop

inStream.Close( )

End Sub

End Module
