C# Generic Collections Part 3: User defined types

In case of generic collection the types of value we want to store under the collections need not be pre-defined types like int,float,double,string etc... But it can also be some user defined types.

Code:

1. using System;  
2. using System.Collections.Generic;  
3. using System.Linq;  
4. using System.Text;  
5. using System.Threading.Tasks;  
6.   
7. namespace genericUserDefined  
8. {  
9.     class Employee  
10.     {  
11.         public int eid { get; set; }  
12.         public string first_name { get; set; }  
13.         public string last_name { get; set; }  
14.         public string department { get; set; }  
15.         public double salary { get; set; }  
16.     }  
17. }  
18.   
19.   
20. //Main class  
21.   
22. using System;  
23. using System.Collections.Generic;  
24. using System.Linq;  
25. using System.Text;  
26. using System.Threading.Tasks;  
27.   
28. namespace genericUserDefined  
29. {  
30.     class Program  
31.     {  
32.         static void Main(string[] args)  
33.         {  
34.             List<Employee> elist = new List<Employee>();//Declare user defined type employee in the list  
35.   
36.             Employee e1 = new Employee();  
37.             e1.eid = 101;  
38.             e1.first_name = "Sujan";  
39.             e1.last_name = "Hasan";  
40.             e1.department = "IT";  
41.             e1.salary = 55000.00;  
42.   
43.             elist.Add(e1);  
44.   
45.             Employee e2 = new Employee();  
46.             e2.eid = 102;  
47.             e2.first_name = "Shakil";  
48.             e2.last_name = "Sorker";  
49.             e2.department = "Networking";  
50.             e2.salary = 75000.00;  
51.   
52.             elist.Add(e2);  
53.   
54.             Employee e3 = new Employee();  
55.             e3.eid = 100;  
56.             e3.first_name = "Shimul";  
57.             e3.last_name = "Hossain";  
58.             e3.department = "CEO";  
59.             e3.salary = 175000.50;  
60.             elist.Add(e3);  
61.   
62.             print(elist);  
63.             Console.ReadKey();  
64.         }  
65.         public static void print(List<Employee> emp)  
66.         {  
67.             foreach (Employee obj in emp)  
68.             {  
69.                 Console.WriteLine(obj.eid+" "+obj.first_name+" "+obj.last_name+" "+obj.department+" "+obj.salary);  
70.             }  
71.         }  
72.     }  
73. }
