使用脚本中的参数执行PowerShell命令

这是我的PowerShell脚本中的哈希表(使用 获取psreadlineoption ):

$theme = @{}
$theme["CommentForegroundColor"] = "DarkGreen"
$theme["CommentBackgroundColor"] = "Black"
$theme["KeywordForegroundColor"] = "Green"
$theme["KeywordBackgroundColor"] = "Black"

我正在尝试使用设置PowerShell主题颜色 设置psreadlineoption 命令:

foreach ($colorTokenKey in $theme.keys) {
    $c=$theme[$colorTokenKey]
    echo "$colorTokenKey will be set to $c"
    $colorTokenArgs = $colorTokenKey.Replace("ForegroundColor"," -ForegroundColor")
    $colorTokenArgs = $colorTokenArgs.Replace("BackgroundColor"," -BackgroundColor")
    $colorTokenArgs = $colorTokenArgs.Split(" ")
    $tokenKind = $colorTokenArgs[0]
    $tokenForegroundOrBackground = $colorTokenArgs[1]
    $params = "-TokenKind $tokenKind $tokenForegroundOrBackground $c"
    echo $params
    & Set-PSReadlineOption $params
}

但当我运行这个时,我

CommandBackgroundColor will be set to White
-TokenKind Command -BackgroundColor White
Set-PSReadlineOption : Cannot bind parameter 'TokenKind'. Cannot convert value "-Tok
enKind Command -BackgroundColor White" to type "Microsoft.PowerShell.TokenClassifica
tion". Error: "Unable to match the identifier name -TokenKind Command -BackgroundCol
or White to a valid enumerator name. Specify one of the following enumerator names a
nd try again:
None, Comment, Keyword, String, Operator, Variable, Command, Parameter, Type, Number
, Member"
At C:\Users\...\PowerShellColors.ps1:88 char:28
+     & Set-PSReadlineOption $params

我做错了什么?
