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.
Example
using System;
using System.Collections.Generic;
public class ListExample
{
public static void Main(string[] args)
{
// Create a list of strings
var names = new List<string>();
names.Add("Sonoo Jaiswal");
names.Add("Ankit");
names.Add("Peter");
names.Add("Irfan");
// Iterate list element using foreach loop
foreach (var name in names)
{
Console.WriteLine(name);
}
}
}
Output:
Output
Sonoo Jaiswal
Ankit
Peter
Irfan
C# List<T> example using collection initializer
Example
using System;
using System.Collections.Generic;
public class ListExample
{
public static void Main(string[] args)
{
// Create a list of strings using collection initializer
var names = new List<string>() {"Sonoo", "Vimal", "Ratan", "Love" };
// Iterate through the list.
foreach (var name in names)
{
Console.WriteLine(name);
}
