帮我修该一下下面的代码

[zjj1211]

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

namespace ConsoleApplication8
{
    class Program
    {
        static void Main(string[] args)
        {
            string logfile = "logfile.txt";
            FileStream fs = new FileStream(logfile,FileMode.OpenOrCreate,FileAccess.Write);

            StreamWriter sw = new StreamWriter(fs);
            StreamReader sr = new StreamReader(fs);

            sw.WriteLine("First log enter");
            sw.WriteLine("Second log enter");

            while (sr.Peek() > -1)
            {
                Console.WriteLine(sr.ReadLine());
            }
            sw.Close();
            sr.Close();
            fs.Close();


        }
    }

要怎么改?使用using自动释放?

[isee1223]

FileStream fs = new FileStream(logfile,FileMode.OpenOrCreate,FileAccess.ReadWrite);
最后貌似还少了个" } ".

        static void Main(string[] args)
        {
            string logfile = "logfile.txt";
            StreamWriter sw = new StreamWriter(logfile, true, Encoding.UTF8);           
            sw.WriteLine("First log enter");
            sw.WriteLine("Second log enter");
            sw.Close();
                        
            StreamReader sr = new StreamReader(logfile,Encoding.UTF8);
            while (!sr.EndOfStream)
            {
                Console.WriteLine(sr.ReadLine());
            }            
            sr.Close();

            Console.ReadLine();
        }
