How to Get Array Length in C# - Step by Step Examples



How to Get Array Length in C# ?

Answer

To get the length of an array in C#, you can use the Length property of the array.



✐ Examples

1 Length of Integer Array

In this example,

  1. We create an integer array named numbers with some values.
  2. We then get the length of the array using Length property of the array object numbers, and store the returned value in length variable.
  3. Array.Length property returns the length of this array.
  4. Finally, we shall print the value in length to standard output.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[] numbers = { 1, 2, 3, 4, 5 };
        int length = numbers.Length;
        Console.WriteLine("Length of array is: " + length);
    }
}

Output

Length of array is: 5

2 Length of String Array

In this example,

  1. We create a string array named names with some values.
  2. We then get the length of the array using Length property of the array object names, and store the returned value in length variable.
  3. Array.Length property returns the length of this array.
  4. Finally, we shall print the value in length to standard output.

C# Program

using System;
class Program
{
    static void Main()
    {
        string[] names = { "Alice", "Bob", "Charlie", "David", "Eve" };
        int length = names.Length;
        Console.WriteLine("Length of array is: " + length);
    }
}

Output

Length of array is: 5
