Using polymorphic simulation, the mobile hard disk, u disk, MP3 plugged into the computer for reading and writing data

Parent class: Abstract class, because do not know what kind of mobile device plugged into the computer, it is not clear how to read and write

    Abstract class Mobilestorage    {        publicabstractvoid  Read ();          Public Abstract void Write ();    }

Mobile HDD Class:

    class Mobiledisk:mobilestorage    {        publicoverridevoid  Read ()        {            Console.WriteLine ("  Mobile Hard drive is reading data ")        ;        }  Public Override void Write ()        {            Console.WriteLine (" mobile Hard disk is writing data ");}    }

USB flash Drive Class:

    class Udisk:mobilestorage    {        publicoverridevoid  Read ()        {            Console.WriteLine ("  USB Stick is reading the data ");        }          Public Override void Write ()        {            Console.WriteLine ("USB stick is writing data ");}    }

MP3 class:

    classMp3:mobilestorage { Public Override voidRead () {Console.WriteLine ("MP3 reading the data"); }         Public Override voidWrite () {Console.WriteLine ("MP3 writing the data"); }         Public voidPlaymusic () {Console.WriteLine ("MP3 is playing music"); }    }

Computer class:

    classComputer {//obtaining a parent class by defining a field        PrivateMobilestorage _ms;  Publicmobilestorage Ms {Get{return_ms;} Set{_ms =value;} }         Public voidCpuread () {ms.read (); }         Public voidCpuwrite () {ms.write (); }        //To get the parent class by using the pass parameter//Public void Cpuread (mobilestorage ms)//{        //Ms.        Read (); //}        //Public void Cpuwrite (mobilestorage ms)//{        //Ms.        Write (); //}}

Main:

        Static voidMain (string[] args) {            //using polymorphic simulation, the mobile hard disk, u disk, MP3 plugged into the computer for reading and writing data//Mobiledisk MD = new Mobiledisk (); //udisk u = new Udisk (); //MP3 mp3 = new MP3 (); //Computer CPU = new computer (); //CPU.            Cpuread (U); //CPU. Cpuwrite (u);Mobilestorage Ms=NewMobiledisk ();//new Udisk ();//new MP3 ();Computer CPU =Newcomputer (); Cpu. Ms=MS; Cpu.            Cpuread (); Cpu.            Cpuwrite (); //CPU.            Cpuread (MS); //CPU. Cpuwrite (MS);Console.readkey (); }
