C# 12 Feature - Inline Arrays

Inline arrays in C# offer a streamlined way to define arrays directly within expressions. This feature, introduced in C# 12, simplifies array initialization, making your code cleaner and more readable.

using System;
class Program
{
    static void Main()
    {
        int[] numbers = [1, 2, 3, 4, 5];
        string[] words = ["hello", "world"];
        object[] mixed = [1, "two", 3.0];
 
       Console.WriteLine(string.Join(", ", numbers)); // Output: 1, 2, 3, 4, 5
       Console.WriteLine(string.Join(", ", words));   // Output: hello, world
       Console.WriteLine(string.Join(", ", mixed));   // Output: 1, two, 3
    }
}

Numbers Array: int[] numbers = [1, 2, 3, 4, 5]; creates an array of integers.

Words Array: var words = ["hello", "world"]; creates an array of strings.

Mixed Array: var mixed = [1, "two", 3.0]; you can even mix types in an object array.

 

Advantages of using inline arrays in C#:

Simplicity: Reduces the verbosity of array initialisation.

Readability: Makes the code easier to understand at a glance.

Inline arrays make initialising arrays effortless and visually cleaner.
