How to Add Elements to an Existing String Array in C#?

Extending String Arrays in C#

Challenge: C#'s arrays are fixed in size. Adding elements to an existing array requires a different approach.

Solution: Using Lists for Dynamic Expansion

The most efficient way to add elements to a string array is to use a List<string>. Lists are dynamic; they automatically resize as you add items.

Here's how you can do it:

<code class="language-csharp">// Create a List to hold strings
List<string> stringList = new List<string>();

// Add elements to the list
stringList.Add("Hello");
stringList.Add("World");

// Convert the List back to an array if needed
string[] stringArray = stringList.ToArray();</code>

This code first creates an empty List<string>. Then, elements are added using the Add() method. Finally, if you need the data back in array form, you can use ToArray() to convert the list. This avoids the overhead of manually creating a new, larger array and copying elements.
