今天写的一段代码关于泛型的简单使用

 1 using System;
 2  using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;

 6 namespace ConsoleApplication1
 7 {
 8     class Program
 9     {
10         static void Main(string[] args)
11         {
12             int List_i = 1;
13             foreach (var i in List())
14             {
15                 Console.WriteLine("{0}:{1},{2}", List_i, i.Id, i.Name);
16                 List_i += 1;
17             }
18             Console.ReadLine();
19         }
20         static public List<User> List() 
21         {
22             List<User> list = new List<User>();
23             list.Add(new User ( 1, "a" ));
24             list.Add(new User ( 2, "b" ));
25             return list;
26         }
27     }
28     class User 
29     {
30         int id;
31         string name;
32         public int Id 
33         {
34             get { return id; }
35             set { id = value; }
36         }
37         public string Name 
38         {
39             get { return name;}
40             set { name = value;} 
41         }
42         public User(int id,string name) 
43         {
44             this.id = id;
45             this.name = name;
46         }
47     }
