Compress and decompress data in c#

In this post,I will show you how to compress and decompress data in  c# using GzipStream class.Below is the code for the same

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Text;

using System.IO.Compression;

namespace CompressDecompress

{

    class Program

    {

        const string CompressFilePath = @"C:\temp\data.zip";

        const string Filename = @"C:\temp\data.txt";

        private const string DeCompressFilePath = @"C:\temp\data1.txt";

        static void Main(string[] args)

        {

            Compress(Filename);

            Decompress(CompressFilePath);

        }

        private static void Decompress(string compressFilePath)

        {

            using (FileStream inputStream = new FileStream(compressFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite))

            {

                using (FileStream outputStream = new FileStream(DeCompressFilePath, FileMode.Create, FileAccess.ReadWrite))

                {

                    using (GZipStream gZipStream = new GZipStream(inputStream, CompressionMode.Decompress))

                    {

                        gZipStream.CopyTo(outputStream);

                    }

                }

            }

        }

        private static void Compress(string filename)

        {

            using (FileStream inputStream = new FileStream(filename, FileMode.OpenOrCreate, FileAccess.ReadWrite))

            {

                Console.WriteLine("Size Before Compression:{0} KB", inputStream.Length / 1024);

                using (FileStream outputStream = new FileStream(CompressFilePath, FileMode.Create, FileAccess.ReadWrite))

                {

                    using (GZipStream gZipStream = new GZipStream(outputStream, CompressionMode.Compress))

                    {

                        inputStream.CopyTo(gZipStream);

                        Console.WriteLine("Size after Compression:{0} KB", outputStream.Length / 1024);

                    }

                }

            }

        }

    }

}
