How To Use Streams in C#

 Chk this out. If possible Give me a better solution.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO.Compression;
using System.IO;

namespace StreamTesting
{
    class Program
    {
        static void Main(string[] args)
        {
            string inputFile= "c:/u.log.gz";
            Console.WriteLine("Enter File Path");
           // inputFile=Console.ReadLine();
            FileInfo file = new FileInfo(inputFile);
            if (file.Exists)
            {
                Decompress(file);
            }
        }

        public static void Decompress(FileInfo file)
        {
            using (FileStream fs = new FileStream(file.FullName, FileMode.Open, FileAccess.Read))
            {
                if (file.Extension == ".gz")
                {
                    Display(new GZipStream(fs, CompressionMode.Decompress, false));
                }
                else
                    Display(fs);

            }
        }

        static void Display(Stream stream)
        {
            Console.WriteLine("Enter No. of lines wanted to Display");
            try
            {
                int n = Int32.Parse(Console.ReadLine());
                int count = -4;
                foreach (string line in ReadFile(stream))
                {
                    if (!line.Contains("#") || count < 0)
                    {
                        Console.WriteLine(line);
                        Console.ReadKey();
                        count++;

                    }
                    if (count == n)
                        break;
                }
            }
            catch (Exception e)
            {
                Console.WriteLine("Enter numbers");
            }
 
        }

        static IEnumerable ReadFile(Stream stream)
        {
            using (StreamReader reader = new StreamReader(stream))
            {
                string line=null;
                while ((line = reader.ReadLine()) != null)
                {
                    yield return line;
                }
            }
        }

    }
}





In this program I am using Gzip stream to printout line by line of the file. Here I learned how to use stream.
