C# API有这样的功能：

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5  6 namespace ConsoleApplication5 7 { 8     abstract class Person 9     {10         private string _name;11         public string Name12         {13             get { return _name; }14         }15         16     }17     class Empoyee : Person18     {19        20 21     }22     class Janitor : Person23     {24       25     }26     class Program27     {28         static void Main(string[] args)29         {30             var people = new List
      
       ();31             people.Add(new Empoyee());32             people.Add(new Janitor());33             foreach (var item in people)34             {35                 Console.WriteLine("Type {0}", item.GetType().Name);36             }37             Console.ReadKey();38         }39     }40 }
      

 

但是我们提倡这样做：The text用来update用户应该来自code本身，而不是来自什么build in framework。为了自由

比如Localization：

1 class Janitor : Person2     {3      。。。4         public override string TypeOfData5         {6             get {
    return Internationlization.Translate(string Janitor);}  7         } 8      。。。9     }
