        public Form1()
        {
            InitializeComponent();
        }
      public static string StringFromBytes(byte[] arr)
        {
            char[] ch = new char[arr.Length / 2];
            for (int i = 0; i < ch.Length; ++i)
            {
                ch[i] = (char)((int)arr[i * 2] + (((int)arr[i * 2 + 1]) << 8));
            }
            return new String(ch);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            ArrayList fileStatistics = new ArrayList();
            String datasetPath = @"D:\Data Sets\Enron";
            DirectoryInfo d = new DirectoryInfo(datasetPath);
            FileInfo[] files = d.GetFiles("*.pdf");
            MessageBox.Show(files.Length.ToString());

            foreach (FileInfo file in files)
            {                
                    //create instance of data class
                    fileAtt f = new fileAtt();

                    f.fFullName = file.FullName;
                    f.fName = file.Name;
                    f.FileSize = file.Length;
                    f.fExtension = file.Extension;
                    byte[] bytes = File.ReadAllBytes(file.FullName);
                    f.content    =Form1.StringFromBytes(bytes);
                   //f.content = Encoding.ASCII.GetString(bytes);
                   f.lastaccesstime = file.LastAccessTime;                
                    fileStatistics.Add(f);
                 //   StreamReader r = new StreamReader(datasetPath);
                 //foreach
                    
                
            }
