Question

谷歌搜索却无法理解这个阵列是如何成为1,8,3阵列的？你怎么看到X是1，Y是8，Z是这个数组的3？

        double[,,] points =
        {
            { {-1, 0, 3}, {-1, -1, -1}, {4, 1, 1 },
            {2, 0.5, 9}, {3.5, 2, -1}, {3, 1.5, 3},
            {-1.5, 4, 2}, { 5.5, 4, -0.5}}
        };

Answer 1

如果你将它分开，你就能看清楚：

double[,,] points ={
    { 
        {-1, 0, 3}, 
        {-1, -1, -1}, 
        {4, 1, 1 },
        {2, 0.5, 9}, 
        {3.5, 2, -1}, 
        {3, 1.5, 3},
        {-1.5, 4, 2}, 
        { 5.5, 4, -0.5}
    }
};

让我们把它分开：

1º这是你的阵列，它包含的一切是：

double[,,] points ={
   {//Top level element (1 dimension since there is only one array inside it)

   }
};

2º顶层内部有八个子阵列（现在我们有（1,8）个维度）：

double[,,] points ={
    { 
        {}, //Subarray 1 (Second Level, with 8 elements)
        {}, //Subarray 2
        {}, //Subarray 3
        {}, //Subarray 4
        {}, //Subarray 5
        {}, //Subarray 6
        {}, //Subarray 7
        {}  //Subarray 8
    }
};

3º最后在8个子阵列的每一个内部有三个元素：

double[,,] points ={
    { 
        {-1, 0, 3}, //Third Level (with 3 elements)
        {-1, -1, -1}, 
        {4, 1, 1 },
        {2, 0.5, 9}, 
        {3.5, 2, -1}, 
        {3, 1.5, 3},
        {-1.5, 4, 2}, 
        { 5.5, 4, -0.5}
    }
};

有了这些，我们终于拥有了所有的维度（1,8,3）。我建议你格式化数组，看清楚它们。

我希望它可以帮到你。

Answer 2

你只需重新格式化，基本上：

double[,,] points =
{
    { // One top-level element
         {-1, 0, 3}, // 8 "middle-level" elements, each of which has 3 elements
         {-1, -1, -1},
         {4, 1, 1 },
         {2, 0.5, 9},
         {3.5, 2, -1},
         {3, 1.5, 3},
         {-1.5, 4, 2},
         { 5.5, 4, -0.5}
    }
};

Answer 3

我重新安排了数组，并添加了一些注释来澄清结构：

double[,,] points =
{   // one element: X
    { // having eight elements: Y
        {-1, 0, 3}, // each having three elements: Z
        {-1, -1, -1}, 
        {4, 1, 1 },
        {2, 0.5, 9}, 
        {3.5, 2, -1}, 
        {3, 1.5, 3},
        {-1.5, 4, 2}, 
        { 5.5, 4, -0.5}
    }
};

隐式点的第一个元素为X，第二个元素为Y，第三个元素为Z.所以元素的数量为1,8,3。
