Oh really? It is the first time I hear it. It's nonsense. How do I assign the values of one array to another? Do I need a function?

If I want to pass an int[] to a function without changing any element, do I have to copy it to another array first? Is this the dumbest thing Microsoft has ever done?

Reference type helps save memory and improve performance.
There is CopyTo function. Array.CopyTo Method

            int[] sourceArray = {0, 1, 2, 3, 4, 5 };
            int[] destinationArray = new int[sourceArray.Length];

            sourceArray.CopyTo(destinationArray, 0);

            destinationArray[0] = -1;
            Console.WriteLine(sourceArray[0].ToString());
