Array concatenation in C#

Question

1. How do I smartly initialize an Array with two (or more) other arrays in C#?

   double[] d1 = new double[5];
   double[] d2 = new double[3];
   double[] dTota         
   
   
           

Answer 1

using System.Linq;

int[] array1 = { 1, 3, 5 };
int[] array2 = { 0, 2, 4 };

// Concat array1 and array2.
var result1 = array1.Concat(array2).ToArray();
