Question

1) const int[] array={1,2,3,4}; //this gives below error

"Error 1 'ConsoleApplication1.Main.array' is of type 'int[]'.
 A const field of a reference type other than string can only be initialized with null"

In my opinion according to error messeagge, it is not meaningfull to use const for reference types.Am i wrong ?

2) How can i concatenate int array ? Example:

int[] x={1,2,3} + {4,5,6};

I know that + operator will not work so what is best way to do it as strings ?

Answer 1

Concat extension method do that. Not high clarity code but does.

(new int[] { 1, 2, 3, 4 }).Concat(new int[] { 5, 6, 7, 8 }).ToArray();
