LESSON 106 OF 674 · ARRAYS I

Static Array Length in C#

Lesson

We can get the length of an array using the .Length property like this:

int[] ourArray = {50, 40, 30};

// Printing the length:
Console.WriteLine(ourArray.Length); // Output: 3

Using the length

We can use the length to access items from the end of an array.

Because arrays are 0-indexed, the index of the last item is length - 1:

int[] ourArray = {50, 40, 30};

// Printing the last item:
Console.WriteLine(ourArray[ourArray.Length - 1]); // Output: 30

// Printing the second to last item:
Console.WriteLine(ourArray[ourArray.Length - 2]); // Output: 40
