如何转置多维数组? [英] How do I Transpose a multi dimensional array?

问题描述

我认为这可能是一个非常简单的问题，但我还没有弄清楚.如果我有一个像这样的二维数组:

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，如下所示:

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.但是如何打印出数组的转置?

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

只需改变彼此的循环:

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];
