I have changed your code a bit so this one works:

var mStream = new MemoryStream(new byte[100]);
var outStream = new System.IO.MemoryStream();

using (var tinyStream = new GZipStream(outStream, CompressionMode.Compress))
{
    mStream.CopyTo(tinyStream);           
}

byte[] bb = outStream.ToArray();

//Decompress                
var bigStream = new GZipStream(new MemoryStream(bb), CompressionMode.Decompress);
var bigStreamOut = new System.IO.MemoryStream();
bigStream.CopyTo(bigStreamOut);
