To declare an integer array in C#, you can use array literals or the new keyword with the array type.

1 Declare and Initialize an Integer Array

In this example,

We declare an integer array named numbers with predefined values using array literals.
We print the array to demonstrate the initialization.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[] numbers = {1, 2, 3, 4, 5};
        Console.WriteLine("Integer Array: " + string.Join(", ", numbers));
    }
}

Output

Integer Array: 1, 2, 3, 4, 5

2 Declare an Empty Integer Array

In this example,

We declare an empty integer array named emptyArray using the new keyword with the array type.
We print the array to demonstrate the declaration.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[] emptyArray = new int[0];
        Console.WriteLine("Empty Integer Array: " + string.Join(", ", emptyArray));
    }
}

Output

Empty Integer Array:
