Powershell-从数组中的每个字符串获取变量

基本上，我试图实现的是

foreach

character in

$IDNumber

它将沿着

$number9prt1

的行吐出一个字符串，并将其放入数组，然后移动到

$IDNumber

中的下一个字符，依此类推

完成后，我希望数组中的

foreach

string获取每个字符串的变量

第一个示例将查看变量

$Number9Prt1

然后

$Number8Prt1

然后

$Number7Prt1

简单地说，我有一个数组，它的值如下

Number9Prt1

然后

Number8Prt1

然后

Number7Prt1

。是否有一种方法可以从数组中获取值，将其转换为变量，从变量中获取字符串并将其放入数组中。

我已经试了好几天了，但是运气不好。。。任何帮助都将不胜感激

多谢各位

原因：我在我的工作场所使用控制台窗口作为一种“GUI”，拥有更大的文本会很有帮助。

我个人只会使用数组。数组的每个索引都可以表示数字：

$Number1Prt2 = "####   "
$Number1Prt3 = "  ##   "
$Number1Prt4 = "  ##   "
$Number1Prt5 = "  ##   "
$Number1Prt6 = "  ##   "
$Number1Prt7 = "###### " 

$Number2Prt1 = " #######  "
$Number2Prt2 = "##     ## "
$Number2Prt3 = "       ## "
$Number2Prt4 = " #######  "
$Number2Prt5 = "##        "
$Number2Prt6 = "##        "
$Number2Prt7 = "######### "

$Number3Prt1 = " #######  "
$Number3Prt2 = "##     ## "
$Number3Prt3 = "       ## "
$Number3Prt4 = " #######  "
$Number3Prt5 = "       ## "
$Number3Prt6 = "##     ## "
$Number3Prt7 = " #######  "

$Number4Prt1 = "##        "
$Number4Prt2 = "##    ##  "
$Number4Prt3 = "##    ##  "
$Number4Prt4 = "##    ##  "
$Number4Prt5 = "######### "
$Number4Prt6 = "      ##  "
$Number4Prt7 = "      ##  "

$Number5Prt1 = "######## "
$Number5Prt2 = "##       "
$Number5Prt3 = "##       "
$Number5Prt4 = "#######  "
$Number5Prt5 = "      ## "
$Number5Prt6 = "##    ## "
$Number5Prt7 = " ######  "

$Number6Prt1 = " #######  "
$Number6Prt2 = "##     ## "
$Number6Prt3 = "##        "
$Number6Prt4 = "########  "
$Number6Prt5 = "##     ## "
$Number6Prt6 = "##     ## "
$Number6Prt7 = " #######  "

$Number7Prt1 = "######## "
$Number7Prt2 = "##    ## "
$Number7Prt3 = "    ##   "
$Number7Prt4 = "   ##    "
$Number7Prt5 = "  ##     "
$Number7Prt6 = "  ##     "
$Number7Prt7 = "  ##     "

$Number8Prt1 = " #######  "
$Number8Prt2 = "##     ## "
$Number8Prt3 = "##     ## "
$Number8Prt4 = " #######  "
$Number8Prt5 = "##     ## "
$Number8Prt6 = "##     ## "
$Number8Prt7 = " #######  "

$Number9Prt1 = " #######  "
$Number9Prt2 = "##     ## "
$Number9Prt3 = "##     ## "
$Number9Prt4 = " ######## "
$Number9Prt5 = "       ## "
$Number9Prt6 = "##     ## "
$Number9Prt7 = " #######  "

$Number0Prt1 = "  #####   "
$Number0Prt2 = " ##   ##  "
$Number0Prt3 = "##     ## "
$Number0Prt4 = "##     ## "
$Number0Prt5 = "##     ## "
$Number0Prt6 = " ##   ##  "
$Number0Prt7 = "  #####   "

$IDNumber = "9873453"
$CharArray =$IDNumber.ToCharArray()

#Creating variables
foreach ($CharArray in [char[]]$CharArray) { $NumberArray += ("$"+"Number"+$CharArray+"Prt"+"1")}

说明：

$Numbers

是一个数组，其中每个索引都包含一个表示数字图形的数组。因此，

$Numbers['0']

包含组成

0

图形的数组元素，

$Numbers['1']

包含组成

1

图形的数组元素，等等。现在您只需要检索包含目标图形的

$Numbers

索引

如果shell中的视觉表示对您很重要，您仍然可以保持：

# For simplicity, I only created 0,1,2,3 indices.
# Each index number matches the graphical number it stores.
$Numbers = @("  #####   "," ##   ##  ","##     ## ","##     ## ","##     ## "," ##   ##  ","  #####   "),
           @("####   ","  ##   ","  ##   ","  ##   ","  ##   ","  ##   ","###### "),
           @(" #######  ","##     ## ","       ## "," #######  ","##        ","##        ","######### "),
           @(" #######  ","##     ## ","       ## "," #######  ","       ## ","##     ## "," #######  ")

$IDNumbers = '20012'
$IDNumbers.ToCharArray() | Foreach-Object { $Numbers["$_"] }

# Output
 #######
##     ##
       ##
 #######
##
##
#########
  #####
 ##   ##
##     ##
##     ##
##     ##
 ##   ##
  #####
  #####
 ##   ##
##     ##
##     ##
##     ##
 ##   ##
  #####
####
  ##
  ##
  ##
  ##
  ##
######
 #######
##     ##
       ##
 #######
##
##
#########

---

您可以基于此方法进行水平显示：

$Numbers = @(
"  #####   ",
" ##   ##  ",
"##     ## ",
"##     ## ",
"##     ## ",
" ##   ##  ",
"  #####   "
),
@(
"####   ",
"  ##   ",
"  ##   ",
"  ##   ",
"  ##   ",
"  ##   ",
"###### "
),
@(
" #######  ",
"##     ## ",
"       ## ",
" #######  ",
"##        ",
"##        ",
"######### "
),
@(
" #######  ",
"##     ## ",
"       ## ",
" #######  ",
"       ## ",
"##     ## ",
" #######  "
)

您只需将连接字符（此处的选项卡）更改为任意一个或一组字符即可。因为每个图形有7个部分，所以可以循环遍历每个部分（索引0-6）。由于我们将每个部分创建为数组的一个元素，因此您拥有一个嵌套数组数组。因此，图形

0

第1部分将是

$Numbers['0'][0]

，图形

3

第4部分将是

$Numbers['3'][3]

---

编辑：使用字母和数字

您可以使用哈希表而不是数组来保存图形。然后可以通过哈希表键访问每个图形数组

$Numbers = @("  #####   "," ##   ##  ","##     ## ","##     ## ","##     ## "," ##   ##  ","  #####   "),
           @("####   ","  ##   ","  ##   ","  ##   ","  ##   ","  ##   ","###### "),
           @(" #######  ","##     ## ","       ## "," #######  ","##        ","##        ","######### "),
           @(" #######  ","##     ## ","       ## "," #######  ","       ## ","##     ## "," #######  ")

$IDNumbers = '20012'
for ($i = 0; $i -lt 7; $i++) {
    ($IDNumbers.ToCharArray() | Foreach-Object { $Numbers["$_"][$i] }) -join "`t"
}

这太棒了，别误会我的意思，我这么做是为了让变量排成一行，然后水平显示。但我非常感谢您的回答。我添加了如何在创建变量时使其显示在shell中。在shell中，它们如何显示并不真正困扰我，但在控制台窗口中，我试图使它们水平显示。在代码中，我抓取值的顶行，添加一个

'n

，然后创建一个循环，移动到第二行，然后是第三行。。。。。然后水平显示人物。我添加了一种水平显示的方式。这就是巫术。完美的非常感谢您首先，您使用chararray变量作为迭代变量，而它应该只是char数组。将其更改为foreach（$chararray中的char）{…使用$char做点什么…}第二，您可以简单地增加控制台的字体大小，为什么要这样做呢？第三，您不希望将$作为变量名的一部分。我将尝试第一个变量，我不是管理员，因此无法保存任何系统更改，但由于某些原因，当计算机重新启动时，所有值都会返回默认值。只是好奇而已。[原因：我在我的工作场所使用控制台窗口作为一种“GUI”，拥有更大的文本会很有帮助。]为什么？仅使用内置GUI功能的Verses Powershell就可以通过say和消息框为您提供帮助？从GUI，特别是人类可访问性（屏幕阅读器、屏幕分辨率等）用例。你的方法将是一个真正的问题。

$hash = [ordered]@{}
$hash['A'] = @('      ####      ','     ##  ##     ','    ##    ##    ','   ##########   ','  ##        ##  ',' ##          ## ','##            ##')
$hash['0'] = @("  #####   "," ##   ##  ","##     ## ","##     ## ","##     ## "," ##   ##  ","  #####   ")
$hash['1'] = @("####   ","  ##   ","  ##   ","  ##   ","  ##   ","  ##   ","###### ")
$hash['2'] = @(" #######  ","##     ## ","       ## "," #######  ","##        ","##        ","######### ")
$hash['3'] = @(" #######  ","##     ## ","       ## "," #######  ","       ## ","##     ## "," #######  ")

$IDNumbers = 'A23012'
for ($i = 0; $i -lt 7; $i++) {
    ($IDNumbers.ToCharArray() | Foreach-Object { $hash["$_"][$i] }) -join "`t"
}
