Compress a strings using C#

The following function will compress a string using GZipStream.

using System;

using System.Collections.Generic;

using System.Text;

using System.IO.Compression;

using System.IO;

 

namespace Compress_and_decompress_string

{

    class Compress

    {

        public static string CompressString(string text)

        {

            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);

 

        }

    }
