.NET 程序设计实验报告 班级： 计科7 姓名： 陈日燊 学号: 3110006131 教师： 广东工业大学2013年 4 月 20 日第二次实验：内容：完成下面的实验2.1和2.2。地点：工学一号馆413/410时间：2013-4-11实验环境与工具：（1）计算机及操作系统：PC机，WindowsXP（2）程序开发平台：Visual Studio 2005/2008/2010实验2.1一实验目的1掌握System.IO类的文件流操作，会处理文件。2. 理解面向对象思想，会使用.NET Framework的类库。3. 熟悉VisualC#.NET的可视化界面，可以使用相关控件。二实验内容1. 编写一个C#应用程序，将一个包含多个子目录和文件的目录复制到另外一个指定的目录下。a）欲复制的目录中包含的文件数和子目录层次未知，必须在程序执行时获得这些信息。b）显示欲复制的目录的相关信息。2. 二战期间，英国情报人员获取德军的一机密电报，电报的内容为：bzdz izu sxgzd vs lh ,vpzg woflsh vs vwrh vhlsddlmp glm wrw gzy vsg .gflyz gstfzu bvsg gzsd hdmlp vml lm ,hghzvy wmz hwiry mvvdgvy izd z hzd vivsg ,ltz tmlo tmlO情报人员已经知道，这段电报的加密方式为：a. 首先将字符串的顺序颠倒。b. 字母互换的规律为：A-Z, B-Y, C-X.X-C, Y-B, Z-A; a-z, b-y, c-x.x-c, y-b, z-a.c. 非字母字符保持不变。请编程帮助情报人员破译这份机密电报。给出注释良好的源程序和程序运行后的结果。三源程序程序一:using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.IO;namespace WindowsFormsApplication2 public partial class Form1 : Form public Form1() InitializeComponent();
