Is there a way of manipulating zip file contents in memory with Powershell?

Question

I\'m currently trying to write a powershell function which works with the output of the Lync powershell cmdlet \"Export-CsConfiguration -AsBytes\". When using implicit Power

Answering my own question here, in case it proves useful to others: (N.B. Requires .NET 4.5)

It looks like using System.IO.Compression.ZipArchive in combination with System.IO.Memorystream is the way forward. I've got this now:

Function Load-CsConfig{
  [System.Reflection.Assembly]::LoadWithPartialName('System.IO.Compression') | Out-Null

  $ZipBytes = Export-CsConfiguration -AsBytes
  $ZipStream = New-Object System.IO.Memorystream
  $ZipStream.Write($ZipBytes,0,$ZipBytes.Length)
  $ZipArchive = New-Object System.IO.Compression.ZipArchive($ZipStream)
  $ZipEntry = $ZipArchive.GetEntry('DocItemSet.xml')
  $EntryReader = New-Object System.IO.StreamReader($ZipEntry.Open())
  $DocItemSet = $EntryReader.ReadToEnd()
  return $DocItemSet
}

Which does exactly what I need.

Thanks all :)
