一、实验目的：
1. 熟悉.NET框架下路径及文件信息的获取方法。
2. 熟悉文本文件、二进制流式文件的读取和保存方法。
二、实验内容及要求：
1、实现选择一个路径，并显示该路径下的所有目录及文件。
2、编程实现显示选中文件的属性信息（大小、最后访问时间、最后修改时间等信息）
3、创建应用程序，实现在窗体关闭后，下次打开时能自动保存窗体的大小和位置（用文本文件保存）。
4、继续完善数据库操作类，实现：将数据库连接信息（服务器IP地址、数据库名）用文本文件配置，在数据库操作类中提供方法从配置文件中读入服务器IP地址、数据库名，实现连接字符串的动态生成。
5、编程实现，将教师信息：教师号（Int16），教师名（string），性别（bool），基本工资（double），写入二进制文件保存。同时实现从二进制文件中读出写入内容。
