What are dynamic arrays in C#?
Dynamic arrays are growable arrays and have an advantage over static arrays. This is because the size of an array is fixed.
To create arrays dynamically in C#, use the ArrayList collection. It represents an ordered collection of an object that can be indexed individually. It also allows dynamic memory allocation, adding, searching and sorting items in the list.
The following is an example showing how to create arrays dynamically in C# −
Example
using System;
using System.Collections;
namespace Demo {
class Program {
static void Main(string[] args) {
ArrayList al = new ArrayList();
al.Add(577);
al.Add(286);
Console.WriteLine("Count: {0}", al.Count);
Console.Write("List: ");
foreach (int i in al) {
Console.Write(i + " ");
}
Console.WriteLine();
Console.ReadKey();
}
}
}Output
Count: 2 List: 577 286
