[英]Copy 2D array from jagged 2D array in into another jagged 2D array
I have jagged 2D array like so: 我有锯齿状的二维数组,像这样:
static void Main(string[] args)
{
int[][,] newArray = new int[2][,];
int[][,] waypoints = new int[4][,]
{
new int[,] {{6,3,4,5,6}},
new int[,] {{1,3,4,5,6}},
new int[,] {{1,4,3,2,1}},
new int[,] {{6,3,4,5,6}}
};
int l = 0;
int m = 0;
for (int i = 0; i < waypoints.Length; i++)
{
for (int j = 0; j < waypoints[i].GetLength(0); j++)
{
for (int k = 0; k < waypoints[i].GetLength(1); k++)
{
if (k == 1 || k == 3)
{
// waypoints[i][j,k].CopyTo(newArray[i][j,k]);
}
l++;
m++;
}
}
}
Console.ReadKey();
}
And I need to extract from each jagged array only [0,1] and [0,3] 2D array and store that in new jagged array - newArray. 而且我需要从每个锯齿状数组中仅提取[0,1]和[0,3] 2D数组,并将其存储在新的锯齿状数组-newArray中。 Please, could you help me, how to do that. 拜托,你能帮助我,怎么做。 Many thanks in advance. 提前谢谢了。
Desired output should look like: 所需的输出应如下所示:
int[][,] newArray = new int[2][,];
{
new int[,] {{3,5}},
new int[,] {{3,5}},
new int[,] {{4,2}},
new int[,] {{3,5}}
};
Try this. 尝试这个。 Note that I expanded the size of newArray to accomodate 4 2D-arrays. 请注意,我扩大了newArray的大小以容纳4个2D数组。
