读出文件内容

Question

        FileStream fs;
        BinaryReader br;
        BinaryWriter bw;
        string s = "";
        public Login()
        {
            InitializeComponent();
        }        private void Form1_Load(object sender, EventArgs e)
        {
            char[] user = { 'j','i','n','g','l','i','x','i','t','o','n','g'};
            cmbjob.SelectedIndex = 0;
            fs = new FileStream(@"C:\Program Files\login.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite,FileShare.Read);
            br = new BinaryReader(fs);
            bw = new BinaryWriter(fs);
            for (int i = 0; i < user.Length; i++)
            {
                bw.Write((int)user[i]+5);
            }
        }
 private void btnlogin_Click(object sender, EventArgs e)
        {
            if (cmbjob.Text == "经理")
            {
                br.BaseStream.Seek(0, SeekOrigin.Begin);
                while (br.PeekChar()> -1)
                {
                    s += br.BaseStream
                }
                MessageBox.Show(s);
            }
            else
            {
                
            }
        }大概的代码是这样的，数组里的每个字符转换成ASCII码，起到加密的作用，文件里面的内容是：
o   n   s   l   q   n   }   n   y   t   s   l   
可是我想把这些读出来的时候却读不出来，麻烦大家看一下要用什么方法才能读出来？谢谢

我用的代码/// <summary>
        /// 读取Txt文件
        /// </summary>
        /// <returns></returns>
        public static ArrayList GetFiles(string FileName)
        {
            #region 数据读取
            try
            {
                FileStream fs = new FileStream(Application.StartupPath + FileName, FileMode.Open, FileAccess.Read);
                StreamReader m_streamReader = new StreamReader(fs, Encoding.GetEncoding("GB2312"));
                //使用StreamReader类来读取文件 
                m_streamReader.BaseStream.Seek(0, SeekOrigin.Begin);
                // 从数据流中读取每一行，直到文件的最后一行
                string strLine = m_streamReader.ReadLine();
                ArrayList arraylist = new ArrayList();
                while (strLine != null)
                {
                    arraylist.Add(strLine);
                    strLine = m_streamReader.ReadLine();
                }
                //关闭此StreamReader对象 
                m_streamReader.Close();
                if (arraylist.Count > 0)
                {
                    return arraylist;
                }
                else
                {
                    return null;
                }
            }
            catch(Exception)
            {
                MessageBox.Show("数据读取失败，请重试！", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return null;
            }
