C# List

C# List<T> class is used to store and fetch elements. It can have duplicate elements. It is found in System.Collections.Generic namespace.

C# List<T> example

Let's see an example of generic List<T> class that stores elements using Add() method and iterates the list using for-each loop.

1. using System;  
2. using System.Collections.Generic;  
3.   
4. public class ListExample  
5. {  
6.     public static void Main(string[] args)  
7.     {  
8.         // Create a list of strings  
9.         var names = new List<string>();  
10.         names.Add("Sonoo Jaiswal");  
11.         names.Add("Ankit");  
12.         names.Add("Peter");  
13.         names.Add("Irfan");  
14.   
15.         // Iterate list element using foreach loop  
16.         foreach (var name in names)  
17.         {  
18.             Console.WriteLine(name);  
19.         }  
20.     }  
21. }  

Output:

Sonoo Jaiswal
Ankit
Peter
Irfan

C# List<T> example using collection initializer

1. using System;  
2. using System.Collections.Generic;  
3.   
4. public class ListExample  
5. {  
6.     public static void Main(string[] args)  
7.     {  
8.         // Create a list of strings using collection initializer  
9.         var names = new List<string>() {"Sonoo", "Vimal", "Ratan", "Love" };  
10.          
11.         // Iterate through the list.  
12.         foreach (var name in names)  
13.         {  
14.             Console.WriteLine(name);  
15.         }  
16.     }  
17. }  

Output:

Sonoo
