正确的解决办法，虽然有点复杂但是正确的~
staticvoid PrintGraph(int level, int start)
{
int[,] arrax = newint[level * 2 + 1, level * 2 + 1];
arrax[level, level] = start;
for (int i = 1; i <= level; i++)
{
//right
int y = level + i;
int x = level - i;
for (int j = 1; j <= 2 * i; j++)
{
int x1 = x + j;
if (j == 1)
{
arrax[x1, y] = arrax[x1, y - 1] + 1;
}
else
{
arrax[x1, y] = arrax[x1 - 1, y] + 1;
}
}
//bottom
x = level + i;
for (int j = 1; j <= 2 * i; j++)
{
int y1 = y - j;
arrax[x, y1] = arrax[x, y1 + 1] + 1;
}
//left
y = level - i;
for (int j = 1; j <= 2 * i; j++)
{
int x1 = x - j;
arrax[x1, y] = arrax[x1 + 1, y] + 1;
}
//top
x = level - i;
for (int j = 1; j <= 2 * i; j++)
{
int y1 = y + j;
arrax[x, y1] = arrax[x, y1 - 1] + 1;
}
}
for (int m = 0; m < level * 2 + 1; m++)
{
for (int n = 0; n < level * 2 + 1; n++)
{
Console.Write(string.Format("{0,3}", arrax[m, n]));
}
Console.WriteLine();
}
}

先把矩阵的宽度算出来(n*2+1)
根据宽度创建一个2唯的数组
然后向数组中填入数据.
然后输出数组

(2n+1)的平方为右上角。然后逆序输出。没圈做一个递归。

请给出详细的code行吗？

非递归算法
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication6 { class Program { static void Main(string[] args) { int c; bool flag; int[,] rect; int col; int row; int add; int num; int totalCount; int op; //操作次数 int direct; //操作方向 0 右 1下 2左 3上 flag = int.TryParse(Console.ReadLine(), out c); if (flag) { rect = new int[2 * c + 1, 2 * c + 1]; col = c; row = c; add = 1; direct = 0; num = 1; op = 0; rect[row, col] = num; totalCount = (2 * c + 1)*(2*c+1); for (int i = 1; i <= totalCount; i++) { if (op == 2) { add++; op = 0; } switch (direct) { case 0: for (int j = 1; j <= add; j++) { col++; num++; if (num > totalCount) break; rect[row, col] = num; } direct = 1; break; case 1: for (int j = 1; j <= add; j++) { row++; num++; if (num > totalCount) break; rect[row, col] = num; } direct = 2; break; case 2: for (int j = 1; j <= add; j++) { col--; num++; if (num > totalCount) break; rect[row, col] = num; } direct = 3; break; case 3: for (int j = 1; j <= add; j++) { row--; num++; if (num > totalCount) break; rect[row, col] = num; } direct = 0; break; } op++; } for (int i = 0; i < 2 * c + 1; i++ ) { for (int j = 0; j < 2 * c + 1; j++) { Console.Write(rect[i, j] + " "); } Console.Write("\n"); } } } } }

简单运行了你的结果，发现2、3的时候就是不对的
