二维数组

 int[,] array = new int[3, 4]
            { 
                { 2,3,4,5},
                {3,4,5,6},
                {5,6,7,8 } 
            };
            //Console.WriteLine(array[1,1]);
            for (int i = 0; i < 3; i++)
            {
                for (int j = 0; j < 4; j++)
                {
                    //Console.WriteLine(array[i,j]);
                    array[i, j] = int.Parse(Console.ReadLine());
                }
            }
