title: Unzip a MemoryStream (containing the zip file) and get the files
body: <p>I have a memory stream that contains a zip file in <code>byte[]</code> format. Is there any way I can unzip this memory stream, without any need of writing the file to disk?</p>
  <p>In general I am using <code>ICSharpCode.SharpZipLib.Zip.FastZip</code> to unzip a file, but is there any way to unzip a memory stream, maybe by storing the files in another <code>MemoryStream</code> or in <code>byte[]</code> format according to the files/folders present in the zip?</p>
  <p>Any way I can use the Memorymapped files feature in this scenario ?</p>
