Question

noob question on c#: how to create a one-dimensional dynamic array? And how to change it later?

thanks.

Answer 1

Instead of using an array, you can use the List<> object in C#.

List<int> integerList = new List<int>();

To iterate on items contained in the list, use the foreach operator :

foreach(int i in integerList)
{
    // do stuff with i
}

You can add items in the list object with Add() and Remove() functions.

for(int i = 0; i < 10; i++)
{
    integerList.Add(i);
}

integerList.Remove(6);
integerList.Remove(7);

You can convert a List<T> to an array using the ToArray() function :

int[] integerArray = integerList.ToArray();

Here is the documentation on List<> object.
