我如何移调多维数组？ [英] How do I Transpose a multi dimensional array?

问题描述

我觉得这可能是一个非常简单的问题，但我一直没能弄明白呢。如果我有一个2维数组，像这样：

I think this might be a pretty simple question, but I haven't been able to figure it out yet. If I've got a 2-dimensional array like so:

int[,] matris = new int[5, 8] { 
       { 1, 2, 3, 4, 5,6,7,8 }, 
       {9,10,11,12,13,14,15,16},
       { 17,18,19,20,21,22,23,24 },
       { 25,26,27,28,29,30,31,32 },
       { 33,34,35,36,37,38,39,40 },

        };

和一个for循环，像这样的：

and a for loop, like this:

  for (int r = 0; r < 5; r++)
        {

            for (int j = 0; j < 8; j++)
                Console.Write("{0} ", matris[r, j]);

            Console.WriteLine();
        }

所以用这个代码，我打印出多维数组。 ？可是我怎么打印出数组的转置

So with this code I am printing out the multi dimensional array. But how do I print out a transpose of the array?

推荐答案

只要改变你的循环与对方：

Just change your loops with each other:

for (int j = 0; j < 8; j++)
{
    for (int r = 0; r < 5; r++)
        Console.Write("{0} ", matris[r, j]);

    Console.WriteLine();
}

创建新的数组：

var newArray = new int[8, 5];
for (int j = 0; j < 8; j++)
    for (int r = 0; r < 5; r++)
        newArray[j, r] = matris[r, j];
