Powershell 脚本在 Windows 7 而不是 Windows 10 中抛出转换错误

Question

首先，我假设我面临的问题是 .Net 问题，因为我可以运行脚本在 Windows 10 中成功，但不能在 Windows 7.

以下是我遇到的错误。因此，我试图通过在 $CharNum 变量周围放置“”（双引号）来解决这个问题。但是，它不起作用。

所以，如果有人能阐明这个问题并帮助我理解为什么这个脚本在 Windows 10 而不是 Windows 7 中有效，我将不胜感激。此外，如果您能帮助我更正代码，使其在 Windows 的两个版本中都兼容，我们将不胜感激。

同样，我假设 .Net 是罪魁祸首。

function GetRandomPassword ([char] $length=10, $count=1) {

if ($length -lt 4) {return $null}

# Define list of numbers, this will be CharType 1
$numbers=$null
For ($a=48;$a –le 57;$a++) {$numbers+=,[char][byte]$a }

# Define list of uppercase letters, this will be CharType 2
$uppercase=$null
For ($a=65;$a –le 90;$a++) {$uppercase+=,[char][byte]$a }

# Define list of lowercase letters, this will be CharType 3
$lowercase=$null
For ($a=97;$a –le 122;$a++) {$lowercase+=,[char][byte]$a }

# Define list of special characters, this will be CharType 4
$specialchars=$null
For ($a=33;$a –le 33;$a++) {$specialchars+=,[char][byte]$a }
For ($a=63;$a –le 64;$a++) {$specialchars+=,[char][byte]$a }
For ($a=61;$a –le 61;$a++) {$specialchars+=,[char][byte]$a }
For ($a=45;$a –le 46;$a++) {$specialchars+=,[char][byte]$a }
For ($a=35;$a –le 38;$a++) {$specialchars+=,[char][byte]$a }
For ($a=42;$a –le 43;$a++) {$specialchars+=,[char][byte]$a }



# Need to ensure that result contains at least one of each CharType
# Initialize buffer for each character in the password
$Buffer = @()
For ($a=1;$a –le $length;$a++) {$Buffer+=0 }

# Randomly chose one character to be number
while ($true) {
$CharNum = (Get-Random -minimum 0 -maximum $length)
if ($Buffer["$CharNum"] -eq 0) {$Buffer["$CharNum"] = 1; break}
}

# Randomly chose one character to be uppercase
while ($true) {
    $CharNum = (Get-Random -minimum 0 -maximum $length)
    if ($Buffer["$CharNum"] -eq 0) {$Buffer["$CharNum"] = 2; break}
}

# Randomly chose one character to be lowercase
while ($true) {
    $CharNum = (Get-Random -minimum 0 -maximum $length)
    if ($Buffer["$CharNum"] -eq 0) {$Buffer["$CharNum"] = 3; break}
}

# Randomly chose one character to be special
while ($true) {
    $CharNum = (Get-Random -minimum 0 -maximum $length)
    if ($Buffer["$CharNum"] -eq 0) {$Buffer["$CharNum"] = 4; break}
}

# Cycle through buffer to get a random character from the available types
# if the buffer already contains the CharType then use that type
$Password = ""
foreach ($CharType in $Buffer) {
    if ($CharType -eq 0) {$CharType = ((1,2,3,4)|Get-Random)}
    switch ($CharType) {
        1 {$Password+=($numbers | GET-RANDOM)}
        2 {$Password+=($uppercase | GET-RANDOM)}
        3 {$Password+=($lowercase | GET-RANDOM)}
        4 {$Password+=($specialchars | GET-RANDOM)}
    }
}
return $Password

}

将路径更改为正确的目的地

$PW = GetRandomPassword -length 25 -count 300 >> C:\ctdInstall\PW.txt

Answer 1

您确定它们运行是相同的 powershell 版本吗？ Win10 有 PS 5.0 built-in 而 Win7 有 PS2.0。较新的 powershell 版本可能有一些额外的保护措施来修复转换错误。

更重要的是：为什么要使用 char？ :S

将其更改为[int]$length = 10，您所有的问题都会消失。

Function GetRandomPassword ([int] $length=10, $count=1) {
