c# - 将两个二维数组混合成1个二维数组

Question

我正在尝试将以前的数组(1 和 2)存储在新数组 3 中的结果可以显示数组 1 的每个结果和每个数组 2，当我分别显示每个数组的结果时，它们是可以的，但是当我尝试将它们混合在数组 3 中，我得到了数组 1 中第一个值和数组 2 中所有值的正确答案，然后出现了很多零。

这是数组 3 的代码

for (int i = 0; i < result1.GetLength(0); i++)
          {
               for (int j = 0; j < result1.GetLength(1); j++)
               {
                   for (int k = 0; k < result2.GetLength(0); k++)
                    {
                      for (int m = 0; m < result2.GetLength(1); m++)
                       {

                            result3[i, j] = result1[i, j] + "," + result2[k, m];
                            Console.WriteLine(result3[i, j]);

                            counter++;
                        }
                    }

                }

            }

这里是完整的代码

double[,] Cranelocations = { { -12.3256, 0.5344 }, { -12.3256, -0.4656 }, { -12.3256, -1.4656 }, { -12.3256, -2.4656 } };

            int counter = 0;

Answer 1

对于每个 m，您将 i 重置为 0 并再次从数组的开头开始写入。

当您递增m 时，您需要继续向前移动索引。

当您合并两个索引时也是如此。当您组合两个迭代以获得索引时，您通常将第一个迭代乘以第二个迭代的长度，然后将它们相加。

for (int m = 0; m < Weights.Length; m++)
{
    int offset = m * Cranelocations.GetLength(0);

    for (int i = 0; i < Cranelocations.GetLength(0); i++)
    {
        for (int j = 0; j < Picklocation.GetLength(0); j++)
        {
            double x = Cranelocations[i, 0] - Picklocation[j, 0];
            double y = Cranelocations[i, 1] - Picklocation[j, 1];

            result1[i + offset, j] = Weights[m] * (Math.Sqrt(Math.Pow(x, 2) + Math.Pow(y, 2)));
        }
    }
}

Console.WriteLine("-----------------------------------------------------------------");

for (int m = 0; m < Weights.Length; m++)
{
    int offset = m * Cranelocations.GetLength(0);

    for (int i = 0; i < Cranelocations.GetLength(0); i++)
    {
        for (int j = 0; j < Setlocation.GetLength(0); j++)
        {
            double x = Cranelocations[i, 0] - Setlocation[j, 0];
            double y = Cranelocations[i, 1] - Setlocation[j, 1];

            result2[i + offset, j] = Weights[m] * (Math.Sqrt(Math.Pow(x, 2) + Math.Pow(y, 2)));
        }
    }
}

for (int i = 0; i < result1.GetLength(0); i++)
{
    int iOffset = i * result1.GetLength(1);

    for (int j = 0; j < result1.GetLength(1); j++)
    {
        for (int k = 0; k < result2.GetLength(0); k++)
        {
            int kOffset = k * result2.GetLength(1);

            for (int m = 0; m < result2.GetLength(1); m++)
            {
                result3[iOffset + j, kOffset + m] = result1[i, j] + "," + result2[k, m];
                Console.WriteLine(result3[iOffset + j, kOffset + m]);

                counter++;
            }
        }
    }
}
