如何制作数组数组？或 powershell 中的数组列表？

Question

$Colors = @{
1         =   'White'               
2         =   'Black'         
3         =   'DarkBlue'    
4         =   'DarkGreen'     
5         =   'DarkCyan'      
6         =   'DarkRed'       
7         =   'DarkMagenta'   
8         =   'DarkYellow'    
9         =   'Gray'          
10        =   'DarkGray'      
11        =   'Blue'          
12        =   'Green'         
13        =   'Cyan'          
14        =   'Red'           
15        =   'Magenta'       
16        =   'Yellow'         
                 
        }

$pixels = 1,2,3,4,5,6
         
foreach ($pixel in $pixels)
{
  Write-Host " " -NoNewline -BackgroundColor $Colors.$pixel
}

我上面有这段代码，我试图用它在 powershell 中绘制像素化图像 window。现在它被设置为只绘制那一行像素。我想知道如何制作一个列表列表、数组数组或数组列表，例如，我可以使用它们来绘制 20x20 像素大小的图像。我熟悉如何在 python 中执行此操作，但不熟悉 powershell，如下所示。多维数组之类的东西。

$pixels = [(1,2,3,4,5,6)],
          [(6,5,4,3,2,1)]
         
foreach ($pixel in $pixels)
{
  Write-Host " " -NoNewline -BackgroundColor $Colors.$pixel
}

经过更多研究，我发现类似下面的内容可能有用，但我不知道如何正确地遍历它

System.Collections.ArrayList]$pixels = @()
$pixels = @(@(1,2,3),@(4,5,6),@(7,8,9))
         
foreach ($pixel in $pixels){ Write-Host "  " -NoNewline -BackgroundColor $Colors.$pixel; Start-Sleep -m 50 }

您仍然可以创建一个 multi-dimensional 数组，但当然您仍然必须循环遍历每个单独的数组，并对每个数组中的每个元素再次循环。

我认为您只是缺少 inner-loop 和代码中的新行：

$Colors = @{
    1         =   'White'               
    2         =   'Black'         
    3         =   'DarkBlue'    
    4         =   'DarkGreen'     
    5         =   'DarkCyan'      
    6         =   'DarkRed'       
    7         =   'DarkMagenta'   
    8         =   'DarkYellow'    
    9         =   'Gray'          
    10        =   'DarkGray'      
    11        =   'Blue'          
    12        =   'Green'         
    13        =   'Cyan'          
    14        =   'Red'           
    15        =   'Magenta'       
    16        =   'Yellow'         
}

$arrays = @(1,2,3,4,5,6), @(6,5,4,3,2,1)
         
foreach ($array in $arrays)
{
  foreach ($position in $array) {
    Write-Host " " -NoNewline -BackgroundColor $Colors[$position]
  }
  Write-Host ""
}
