How to get the last element of an array in C#

In this snippet, we are going to learn about how to get the last element of a array in C#.

– Consider, that we have the following array:

int[] arr = { 2, 4, 6, 8, 10};

Now, we want to get the last element 10 from the above array.

Getting the last element

To access the last element of an array, we can use the subscript syntax [] by passing the array.Length-1 which is the index of the last element.

Example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace HelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] arr = { 2, 4, 6, 8, 10 };
            int lastElement = arr[arr.Length - 1];
            Console.WriteLine("Last element is: " + lastElement);         
            Console.WriteLine("Press Enter Key to Exit..");
            Console.ReadLine();

        }
    }
}

Output:

– Similarly, we can also use the Linq Last() method in C# to get the last element of an array like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace HelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
           
            int[] arr = { 2, 4, 6, 8, 10 };
            int lastElement = arr.Last();
            Console.WriteLine("Last element is: " + lastElement);         
            Console.WriteLine("Press Enter Key to Exit..");
            Console.ReadLine();

        }
    }
}
