1、USB在日常中已经广泛被使用，手机，MP3，MP4，相机等都采用了USB接口。本文向大家介绍一个C#实现的USB接口操作类。namespace ConsoleApplication1{    class Program    {        static void Main(string[] args)        {            USB usb;            usb = new UDisk();//插入U盘            usb.OutputFile();//从U盘读出文件            usb.InputFile();//

2、往U盘写入文件            usb.Dispose();//拔出U盘            Console.WriteLine("");            usb = new MDisk();//插入移动硬盘            usb.OutputFile();//从移动硬盘读出文件            usb.InputFile();//往移动硬盘写入文件            usb.Dispose();//拔出移动硬盘            Console.WriteLine("");            usb = new MP4();

3、//插入MP4            usb.OutputFile();//从MP4读出文件            usb.InputFile();//往MP4写入文件            usb.Dispose();//拔出MP4            Console.ReadKey();        }        //USB接口        public interface USB : IDisposable        {            void OutputFile();//读出文件            void InputFile()

4、;//写入文件        }        //U盘        public class UDisk : USB        {            public UDisk()            {                Console.WriteLine("U盘准备就绪...");            }            public void OutputFile()            {                Console.WriteLine("从U盘读出文件");            }           

5、 public void InputFile()            {                Console.WriteLine("往U盘写入文件");            }            public void Dispose()            {                Console.WriteLine("U盘已被拔出");            }        }        //移动硬盘        public class MDisk : USB        {            public MDisk

6、()            {                Console.WriteLine("移动硬盘准备就绪...");            }            public void OutputFile()            {                Console.WriteLine("从移动硬盘读出文件");            }            public void InputFile()            {                Console.WriteLine("往移动硬盘写入文件");     

7、       }            public void Dispose()            {                Console.WriteLine("移动硬盘已被拔出");            }        }        //MP4        public class MP4 : USB        {            public MP4()            {                Console.WriteLine("MP4准备就绪...");            }
