c# - 以矩阵格式打印二维数组

Question

我有一个二维数组如下:

long[,] arr = new long[4, 4] {{ 0, 0, 0, 0 },
                              { 1, 1, 1, 1 },
                              { 0, 0, 0, 0 },
                              { 1, 1, 1, 1 }};

我想以矩阵格式打印此数组的值，例如:

0 0 0 0
1 1 1 1
0 0 0 0
1 1 1 1

我该怎么做？

Answer 1

你可以这样做(稍微修改数组以显示它适用于非方形数组):

        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();
