I am trying to understand why my code doesn't execute as desired. It creates a GZipStream, and then saves the object as compressed file on my hard drive, but the saved file is always 0 bytes.

Now I know how to save a file using GZipStream, but, my question is not how to do it. My question is purely why does this code save 0 bytes (or why FileStream works and memory doesn't).

private void BegingCompression()
{
    var bytes = File.ReadAllBytes(this.fileName);
    using (MemoryStream ms = new MemoryStream(bytes))
    {
        ms.ReadByte();
        using (FileStream fs =new FileStream(this.newFileName, FileMode.CreateNew))
        using (GZipStream zipStream = new GZipStream(ms, CompressionMode.Compress, false))
        {
            zipStream.Write(bytes, 0, bytes.Length);
        }
    }
}

In regards to the source code, this.fileName = c:\Audio.wav and the newFileName is c:\Audio.wav.gz (but have also tried c:\audio.gz)
