Using the Length Property

A number of benefits result because C# implements arrays as objects. One comes from the 

fact that each array has associated with it a 

Length

 property that contains the number of 

elements that an array can hold. Thus, each array provides a means by which its length can 

be determined. Here is a program that demonstrates this property:

// Use the Length array property.

using System;

class LengthDemo {

  static void Main() {

    int[] nums = new int[10];

    Console.WriteLine("Length of nums is " + nums.Length);

    // Use Length to initialize nums.

    for(int i=0; i < nums.Length; i++)

      nums[i] = i * i;

    // Now use Length to display nums.

    Console.Write("Here is nums: ");

    for(int i=0; i < nums.Length; i++)

      Console.Write(nums[i] + " ");

    Console.WriteLine();

  }

}

This program displays the following output:

Length of nums is 10

Here is nums: 0 1 4 9 16 25 36 49 64 81
