wyświetlanie tablicy w formie macierzy

Jak w c# wyświetlić w formie macierzy tablice dwuwymiarową o rozmiarze 2x3, proszę o pomoc

using System;
 
public class Test
{
	public static void Main()
	{
		long[,] arr = new long[5, 4] { { 1, 2, 3, 4 }, { 1, 1, 1, 1 }, { 2, 2, 2, 2 }, { 3, 3, 3, 3 }, { 4, 4, 4, 4 } };
 
        int rowLength = arr.GetLength(0);
        int colLength = arr.GetLength(1);
 
        for (int i = 0; i < rowLength; i++)
        {
            for (int j = 0; j < colLength; j++)
            {
                Console.Write(string.Format("{0} ", arr[i, j]));
            }
            Console.Write(Environment.NewLine + Environment.NewLine);
        }
        Console.ReadLine();
	}
}

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication29
{
    class Program
    {
        static void Main(string[] args)
        {
            int[,] tab = new int[2,3];
            Console.WriteLine("Podaj elementy tablicy");
            for (int i = 0; i < 2; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    Console.Write("tabA[{0},{1}]: ", i, j);
                    tab[i, j] = Convert.ToInt32(Console.ReadLine());
                }

            }
            Console.Clear();
            for (int i = 0; i < 2; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    Console.Write(tab[i, j] + "\t");
                }
                Console.WriteLine();
            }
            Console.ReadKey();
        }
    }
}

czy to także jest wyświetlenie w formie macierzy?
