try this :
static void Main(string[] args)
        {
            int[] arr1 = { 1, 2, 3, 4, 5, 6, 7, 8 };
            int[,] arr2 = new int[4, 2];
            int i = 0;
            //populating 2D Array
            for (int row = 0; row < 4; row++)
            {
                for (int col = 0; col < 2; col++)
                {
                    arr2[row, col] = arr1[i];
                    i++;
                }
            }
            //displaying 2D array
            for (int row = 0; row < 4; row++)
            {
                for (int col = 0; col < 2; col++)
                {
                    Console.Write(String.Format("{0} ", arr2[row, col]));
                }
