c# - Reverse a multidimensional array 4 times -


for simple game, need scoreboard generated dynamically on startup. scoreboard stored multidimensional array in c#. generating base scores isn't hard, problem array should reversed 4 times shown below.

the multidimensional array:

int[,] scoreboard = new int[4, 4];

the base figures:

     {       5,  10,  15,  20      10,  15,  20,  25      15,  20,  25,  30     }

should become:

     {       5,  10,  15,  20,  20,  15,  10,   5      10,  15,  20,  25,  25,  20,  15,  10      15,  20,  25,  30,  30,  25,  20,  15      15,  20,  25,  30,  30,  25,  20,  15      10,  15,  20,  25,  25,  20,  15,  10       5,  10,  15,  20,  20,  15,  10,   5 } 

var result = arrayreflection(scoreboard);         public static t[,] arrayreflection<t>(t[,] arr) {     // number of rows in array     int m = arr.getlength(0);     // number of columns in array     int n = arr.getlength(1);     var res = new t[m*2, n*2];      for(int r=0; r<m; r++)         for(int c=0; c<n; c++)     {         res[r,c] = arr[r,c];         res[r,n + c] = arr[r, n - c - 1];         res[r + m,c] = arr[m - r - 1, c];         res[r+m,n+c] = arr[m - r - 1, n - c - 1];        }      return res;      }
