title: Extract zip from stream to stream
body: <p>I have SqlDatabase. In one column in database I have binary data, I checked and this is zip file. I downloaded this file with entity framework to byte[]. In this zip file I have always one single xml file. Now I want to extract this xml file from byte[] to byte[] or to string. Next I want to read this xml from string, byte[] and read one value. I don't know how to extract zip file from byte[] to byte[]/string.</p>
  
  <p>Best regards</p>
