C# for Programmers: A Practical Guide

Initializing Arrays

Explore how to initialize arrays in C#. Learn different techniques including static and dynamic array initialization, implicit typing with var, and how to access array elements using zero-based indexing.

We'll cover the following...

Initializing Static Arrays

An array can be declared and filled with the default value using square bracket ([]) initialization syntax. For example, creating and initializing an array of 5 integers:

C#
using System;
public class MainClass {
   public static void Main(String [] args)
   {
        int[] arr = { 24, 2, 13, 47, 45 };
        foreach(var item in arr)
        {
            Console.WriteLine(item.ToString());
        }
     
   }
}

Example Explanation

In the above example, in line 7 we have an array arr. We don’t need to specify it’s size - the compiler will automatically know that it’s an array of size 5 ...
