Using GZIP make the file size larger!!

     byte[] buffer = new byte[1];
                    sread = new System.IO.FileStream(@"C:\Users\mm\Desktop\code.txt", System.IO.FileMode.Open, System.IO.FileAccess.Read);
                    swrite = new System.IO.FileStream(@"C:\Users\mm\Desktop\0.txt", System.IO.FileMode.Create, System.IO.FileAccess.Write);

                    System.IO.Compression.GZipStream g = new     System.IO.Compression.GZipStream(swrite, System.IO.Compression.CompressionMode.Compress,true);

br = new System.IO.BinaryReader(sread);
bw = new System.IO.BinaryWriter(swrite);
while (true)
{
    try
    {
        buffer= br.ReadBytes(1);
        g.Write(buffer, 0, 1);
    }
    catch { break; }
}
sread.Close();
swrite.Close();
br.Close();
bw.Close();
