  //decompress the data MemoryStream compressed = new MemoryStream(Buffer); MemoryStream uncompressed = new MemoryStream(); using (GZipStream s = new GZipStream(compressed,CompressionMode.Decompress)) { int size = 2048; byte[] data = new byte[2048]; while (true) { size = s.Read(data, 0, data.Length); if (size > 0) { uncompressed.Write(data, 0, size); } else { break; } } }

  I have 2 problems 1. File's size is bigger after being compressed 2. I can't open a file after being decompressed this is my snipe code: FileStream fromFile = File.OpenRead("c:\\1.pdf"); FileStream toFile = File.Create("c:\\1.zaz"); GZipStream gZipStream = new GZipStream(toFile, CompressionMode.Compress); int mybyte = fromFile.ReadByte(); while (mybyte != -1) { gZipStream.WriteByte((byte)mybyte); mybyte = fromFile.ReadByte(); } Console.WriteLine("Compress completely"); gZipStream.Close(); // Gi?i nén file fromFile = File.OpenRead("c:\\1.zaz"); toFile = File.Create("c:\\2.pdf"); gZipStream = new GZipStream(fromFile, CompressionMode.Decompress); mybyte = gZipStream.ReadByte(); while (mybyte!=-1) { toFile.WriteByte((byte)mybyte); mybyte = gZipStream.ReadByte(); } gZipStream.Close(); Console.Write("Decompress completely"); Console.ReadLine(); May i code something wrong ?
