Just for the fun of it, I ran this:
int cap = 100000;
Stopwatch sw1 = new Stopwatch();
sw1.Start();
int[] ix = new int[cap];
for (int x = 0; x < cap; x++)
{
ix[x] = 1;
}
sw1.Stop();
Stopwatch sw2 = new Stopwatch();
sw2.Start();
List<int> iy = new List<int>(cap);
for (int y = 0; y < cap; y++)
{
iy.Add(y);
}
sw2.Stop();
Console.WriteLine(cap.ToString() + " int[]=" + sw1.ElapsedTicks.ToString());
Console.WriteLine(cap.ToString() + " List<int>=" + sw2.ElapsedTicks.ToString());
Console.ReadKey();
And got this:
100000 int[]=1796542
100000 List=2517922
I tried it in elapsed milliseconds and got 0 and 1 respectively. Clearly the int[] is way faster, but unless you're talking huge arrays, I'd say it is just nominal.
List<int>
because you use automatic resizing, then use it. If you just need a static size array, useint[]
