C#: Any faster way of copying arrays?

I have an integer array

int[] a;

I want to assign a copy of it(not reference) to

int[] b;

what is the easier way to do it?

Answer 1

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);

Answer 2

I think simplest way would be

int[] b = a.ToArray();
