How to 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);
                    }

                }

            }
        }
    }
}
