Compress and Decompress text using System.IO.Compression...

I'm lazy today. This code was copied directly from internet for my personal reference.

    using System;
    using System.Text;
    using System.IO;
    using System.IO.Compression;

    public static class GZipStreamUtility
    {
        public static string Compress(string text)
        {
            if (String.IsNullOrEmpty(text)) return String.Empty;

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

            ms.Position = 0;
            MemoryStream outStream = new MemoryStream();

            byte[] compressed = new byte[ms.Length];
            ms.Read(compressed, 0, compressed.Length);

            byte[] gzBuffer = new byte[compressed.Length + 4];
            System.Buffer.BlockCopy(compressed, 0, gzBuffer, 4, compressed.Length);
            System.Buffer.BlockCopy(BitConverter.GetBytes(buffer.Length), 0, gzBuffer, 0, 4);

            return Convert.ToBase64String(gzBuffer);
        }

        public static string Decompress(string compressedText)
        {
            if (String.IsNullOrEmpty(compressedText)) return String.Empty;

            byte[] gzBuffer = Convert.FromBase64String(compressedText);
            using (MemoryStream ms = new MemoryStream())
            {
                int msgLength = BitConverter.ToInt32(gzBuffer, 0);
                int length = gzBuffer.Length - 4;
                ms.Write(gzBuffer, 4, length);

                byte[] buffer = new byte[msgLength];

                ms.Position = 0;
                using (GZipStream zip = new GZipStream(ms, CompressionMode.Decompress))
                {
                    zip.Read(buffer, 0, buffer.Length);
                }

                return Encoding.UTF8.GetString(buffer);
            }
        }
    }
