让我们从一个简单的16 x 16整数阵列开始 如何以90度顺时针顺序将'SomeValue'插入数组中。
int[] image = new int[16 * 16];
for (int x = 0; x < 16; x++)
{
for (int y = 0; y < 16; y++)
{
int someValue = x * y;
// This is the line I think is wrong
image[x + (y * 16)] = someValue;
}
}
结果应该类似于下面的旋转数组。
正常顺序:
0,1,2,
3,4,5,
6,7,8,顺时针旋转:
6,3,0,
7,4,1,
8,5,2,
答案 0 :(得分:6)
你在找这样的东西吗?
0 0 0 1 1 1 2 2 2 x
0 1 2 0 1 2 0 1 2 y
= = = = = = = = =
6 3 0 7 4 1 8 5 2 m*(m-1-y)+x
对于 m = 3 。
const int m = 16;
int[] image = new int[m * m];
for (int x = 0; x < m; x++)
{
for (int y = 0; y < m; y++)
{
int someValue = x * y;
image[m*(m-1-y)+x] = someValue;
}
}

按照@Albin Sunnanbos的建议并使用二维数组。然后看看this related question。
答案 2 :(得分:1)
如果你想生成旋转的数组,你可以这样做
int[,] image = new int[16 , 16];
int current = 0;
for (int x = 15; x >= 0; x--)
{
for (int y = 0; y < 16; y++)
{
image[x, y] = current;
current++;
}
}
// Output
for (int y = 0; y < 16; y++)
{
for (int x = 0; x < 16; x++)
{
Console.Write(image[x,y] + ", ");
}
Console.WriteLine();
}
