CompressionService - .Net Gzip based compression service .

Compress

byte[] buffer = Encoding.UTF8.GetBytes(text);
var ms = new MemoryStream();
using (var zip = new GZipStream(ms, CompressionMode.Compress, true))
  {
    zip.Write(buffer, 0, buffer.Length);
  }

ms.Position = 0;
var compressed = new byte[ms.Length];
ms.Read(compressed, 0, compressed.Length);
var gzBuffer = new byte[compressed.Length + 4];
Buffer.BlockCopy(compressed, 0, gzBuffer, 4, compressed.Length);
Buffer.BlockCopy(BitConverter.GetBytes(buffer.Length), 0, gzBuffer, 0, 4);
return Convert.ToBase64String(gzBuffer);

Decompress

byte[] gzBuffer = Convert.FromBase64String(compressedText);
using (var ms = new MemoryStream())
{
  int msgLength = BitConverter.ToInt32(gzBuffer, 0);
  ms.Write(gzBuffer, 4, gzBuffer.Length - 4);
  byte[] buffer = new byte[msgLength];
  ms.Position = 0;
  using (var zip = new GZipStream(ms, CompressionMode.Decompress))
    {
      zip.Read(buffer, 0, buffer.Length);
    }
return Encoding.UTF8.GetString(buffer);
