Merge 2 arrays using LINQ

Question

I have two simple array and I would like to merge using join linq:

int[] num1 = new int[] { 1, 55, 89, 43, 67, -3 };
int[] num2 = new int[] { 11, 35, 79, 23         


        

Answer 1

var result = num1.Concat(num2);

Doesn't allocate any memory. Is this sufficient for your needs?
