C#: 抽象类与抽象方法

1.代码

     class Program
     {
         static void Main(string[] args)
         {
             for (int i = ; i < ; i++)
             {
                 if (i %  == )
                 {
                     StorageDevice storge1 = new Upan("sandisk--" + i.ToString());
                     storge1.Inputdevice();
                     storge1.WriteDataToDevice();
                 }
                 else if (i %  == )
                 {
                     StorageDevice storge2 = new YingPan("westdata--" + i.ToString());
                     storge2.Inputdevice();
                     storge2.WriteDataToDevice();
                 }
                 else if (i %  == )
                 {
                     StorageDevice storge3 = new MobliePhone("iphone--" + i.ToString());
                     storge3.Inputdevice();
                     storge3.WriteDataToDevice();
                 }
             }
             Console.ReadKey();
         }
     }

     abstract class StorageDevice
     {
         public abstract void Inputdevice();
         public abstract void WriteDataToDevice();
     }

     class Upan : StorageDevice
     {
         public Upan(string name)
         {
             this.Name = name;
         }

         private string Name;
         public override void Inputdevice()
         {
             Console.WriteLine("U pan ({0}) input the computer.....", Name);
         }

         public override void WriteDataToDevice()
         {
             Console.WriteLine("U pan ({0}) write data.....", Name);
         }
     }

     class MobliePhone : StorageDevice
     {
         private string Name;
         public MobliePhone(string name)
         {
             this.Name = name;
         }
         public override void Inputdevice()
         {
             Console.WriteLine("Mobile Phone ({0}) input the computer....", Name);
         }
         public override void WriteDataToDevice()
         {
             Console.WriteLine("Mobile Phone ({0}) write data....", Name);
         }
     }

     class YingPan : StorageDevice
     {
         public YingPan(string name)
         {
             this.Name = name;
         }
         public string Name { get; private set; }

         public override void Inputdevice()
         {
             Console.WriteLine("Ying pan ({0}) input the computer...", Name);
         }
         public override void WriteDataToDevice()
         {
             Console.WriteLine("Ying pan ({0}) write data...", Name);
         }
     }
