Hello, I've been trying to unzip a file in Visual Basic .Net (03) but
I'm getting an error. I do get the destination directory and I do get
the first extracted file, but then it stops and I get an wrong local
header signature error. I've added the SharpZipLib.dll library to my
project, so that's what I'm using. The zip files contains 9 text
files.
This is the error I get:
An unhandled exception of type 'ICSharpCode.Sh arpZipLib.ZipEx ception'
occurred in sharpziplib.dll
Additional information: Wrong Local header signature-1826153501
I have the following in the top of my code:
Imports System
Imports System.IO
Imports ICSharpCode.Sha rpZipLib.Zip
This is what I have in my button:
Private Sub btnUnzip_Click( ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles btnUnzip.Click
Dim fileName As String = Path.GetFullPat h("c:\testing.z ip")
Dim destPath As String = Path.GetFullPat h("c:\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() <==== This is where the
error occurs!
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)
MsgBox("writing ")
Loop
outStream.Close ()
Loop
inStream.Close( )
End Sub
Any help would be greatly appreciated.
Thanks.
