Create a copy of integer array [duplicate]

Answer 1

You can use Array.CopyTo method.

int[] a = new[] { 1, 2, 3 };
int[] b = new int[3];
a.CopyTo(b,0);

Answer 2

I think simplest way would be

int[] b = a.ToArray();

Answer 3

You can use the native Clone method, try something like this:

int[] b = (int[])a.Clone();

Other options are, using linq:

using System.Linq;

// code ...
int[] b = a.ToArray();

And copying the array

int[] b = new int[a.Length];
a.CopyTo(b, 0);
