            FileStream fs = new FileStream(@"E:\\1.txt", FileMode.Open, FileAccess.Read);
             StreamReader m_streamReader = new StreamReader(fs) ; 
          //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，并在richTextBox1中显示出内容
            this.richTextBox1.Text = "" ;
            string strLine = m_streamReader.ReadLine ( ) ;
            while ( strLine != null )
            {

              strLine = m_streamReader.ReadLine ( ) ;
            }
            //关闭此StreamReader对象
