Example

using System;
using System.Collections.Generic;

List<int> numbers = new List<int>();

// Fill the List<int> by using the Add method
foreach (int number in new int[12]{10, 9, 8, 7, 7, 6, 5, 10, 4, 3, 2, 1})
{
    numbers.Add(number);
}

// Insert an element in the penultimate position in the list, and move the last item up
// The first parameter is the position; the second parameter is the value being inserted
numbers.Insert(numbers.Count-1, 99);

// Remove the first element whose value is 7 (the 4th element, index 3)
numbers.Remove(7);

// Remove the element that's now the 7th element, index 6 (10)
numbers.RemoveAt(6);

// Iterate the remaining 11 elements using a for statement
Console.WriteLine("Iterating using a for statement:");
for (int i = 0; i < numbers.Count; i++)
{
    int number = numbers[i];  // Note the use of array syntax
    Console.WriteLine(number);
}

// Iterate the same 11 elements using a foreach statement
Console.WriteLine("\nIterating using a foreach statement:");
foreach (int number in numbers){    Console.WriteLine(number);}
