用foreach遍历二维数组

static void Main(string[] args)        {            object[,] dataArray = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } };            int count = 0;            foreach (object item in dataArray)            {                               Console.Write(item);                Console.Write(" ");                count++;                if (count % dataArray.GetLength(1) == 0)                {                    Console.WriteLine();                }            }        }
