See more Zip Examples

Demonstrates how to unzip each file contained in a .zip to an in-memory byte array. VB.NET

Dim success As Boolean = False

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim zip As New Chilkat.Zip

success = zip.OpenZip("qa_data/zips/test.zip")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Iterate of each entry in the zip.
' An entry can be a file or directory entry.  For each file, unzip to a byte array.
Dim numEntries As Integer = zip.NumEntries
Debug.WriteLine("NumEntries = " & numEntries)

Dim entry As New Chilkat.ZipEntry
Dim i As Integer = 0
While i < numEntries
    zip.EntryAt(i,entry)
    If (entry.IsDirectory = False) Then
        Dim fileData() As Byte = entry.Inflate()
        ' Do whatever you wish with the file data...
    End If

    i = i + 1
End While

zip.CloseZip()

Debug.WriteLine("Finished.")
