Ranges and indices

C# 8 comes with ranges, which allow you to take a slice of an array or string. Before, if you wanted to get only the first three numbers of an array, you had to iterate through the array and use a condition to find out which values you wanted to use. Let's take a look at an example:

using System;
namespace ConsoleApp6
{
    class Program
    {
        static void Main(string[] args)
        {
            var numbers = new int[] { 1, 2, 3, 4, 5 };
            foreach (var n in numbers)
            {
                if(numbers[3] == n) { break; } 
                Console.WriteLine(n);
            }
            Console.ReadKey();
        }
    }
}

With ranges, you can easily slice the array and take whatever value you want, as shown in the following code:

using System;
namespace ConsoleApp6
{
 class Program
 {
 static void Main(string[] args)
 {
 var numbers = new int[] { 1, 2,...
