Finding the last index of an array

Question

How do you retrieve the last element of an array in C#?

Answer 1

Array starts from index 0 and ends at n-1.

static void Main(string[] args)
{
    int[] arr = { 1, 2, 3, 4, 5 };
    int length = arr.Length - 1;   // starts from 0 to n-1

    Console.WriteLine(length);     // this will give the last index.
    Console.Read();
}
