Ist es nur ich oder ist Powershell Probleme beim Lesen Bereich von Zahlen 6-9 (von 1-52)?

Question

Ich stoße auf einige Probleme, bei denen die Benutzereingabe validiert werden sollte, wenn die Nummern 1-52 eingegeben werden. Allerdings Zahlen 6-9 die nur Zahlen sind, wird es einen Fehler aus irgendeinem Grund geben ...

Hier ist der Code:

Function PrintArrayAsGridWithDisplayNumber 
{ 
    param([string[]]$Array,[ValidateRange(1,24)][int]$ColumnCount) 

    [int]$arrDisplayNumCounter = 1 
    $GridSplat = @{ 
     InputObject = $Array|ForEach-Object { 
      New-Object psobject -Property @{'Value' = "$arrDisplayNumCounter - " + $_}; 
      $arrDisplayNumCounter++ 
     } 
     Property = 'Value' 
    } 

    if(-not $PSBoundParameters.ContainsKey('ColumnCount')) 
    { 
     $GridSplat['AutoSize'] = $true 
    } 
    else 
    { 
     $GridSplat['Column'] = $ColumnCount 
    } 

    $table = Format-Wide @GridSplat | Out-String 
    Write-Host $table 
}

[String[]]$validAdProperties = @('SamAccountName', 'msRTCSIP-UserEnabled', 'msRTCSIP-OptionFlags', 'msRTCSIP-PrimaryUserAddress', 'msRTCSIP-PrimaryHomeServer',

[Int]$displayDemoNumber = 40 
[Int]$numOfDisplayColumns = 3 
[String]$displayDemoNumberValue = $validAdProperties[$displayDemoNumber - 1] 

PrintArrayAsGridWithDisplayNumber $validAdProperties $numOfDisplayColumns 

$selectedAdPropertiesQuery = @() 
$minValidNumber = 1 
$maxValidNumber = $validAdProperties.length 
While (($userInput -notlike "f*")) 
{ 
    # Ask user input 
    If (!($selectedAdPropertiesQuery)) 
    { 
     $userInput = Read-Host " Enter number to select property to export in search results csv file (e.g.: for $displayDemoNumberValue, enter $displayDemoNumber)" 
    } Else { 
     $userInput = Read-Host " Enter number to select property to add in search results csv file, or enter `"f`" if finished" 
    } 

    # Write error if user input was not valid number or f. Else add search value to array if number is valid and not like f. 
    If ((($userInput -lt $minValidNumber) -or ($userInput -gt $maxValidNumber)) -and ($userInput -notlike "f*")) # write warning and do not include input as a value 
    { 
     Write-Host '$minValidNumber =' $minValidNumber 
     Write-Host '$maxValidNumber =' $maxValidNumber 
     Write-Host '$userInput =' $userInput 
     Write-Warning "Invalid number entered: $userInput `nnumber was out of range($minValidNumber - $maxValidNumber)" 
     Write-Host "" 
    } ElseIf ((($userInput -ge $minValidNumber) -or ($userInput -le $maxValidNumber)) -and ($userInput -notlike "f*")) { 
     $userValidatedInput = $validAdProperties[$userInput - 1] # selected property 
     $selectedAdPropertiesQuery += $userValidatedInput 
     Write-Host "User Properties Selected = $selectedAdPropertiesQuery" 
     Write-Host "" 
    } 
} 

Write-Output $selectedAdPropertiesQuery 
}

Hinweis: Wenn ich die Read-Host-[Int]Read-Host werfen , die Nummern werden erfolgreich sein, aber es wird ein Fehler ausgegeben, wenn Sie f eingeben, was eine Endlosschleife verursacht. Ich habe verschiedene Dinge ausprobiert, aber ich kann es einfach nicht richtig verstehen.

Wenn jemand mir helfen könnte zu verstehen, würde ich es begrüßen. Vielen Dank.

Answer 1

Wenn Sie Read-Host verwenden, wird die Eingabe eine string, wenn Sie dann versuchen, $userInput Zahlen zu vergleichen, ist es den ASCII-Wert für $userInput verwendet, wenn die Zeichenfolge ein einzelnes Zeichen ist.

Beispiel:

# If I input 6 here... 
$userInput = Read-Host " Enter number to select property to add in search results csv file, or enter 'f' if finished" 

# ...this will show 54 
[byte][char]$userInput 

# if Max is set to 52, this will be true, since 54 is naturally larger than 52 
$userInput -gt $maxValidNumber 

Um dies zu beheben, können Sie versuchen $userInput mit [int] in Ihren Scheck in einen int zu zwingen, wie folgt aus:

(([int]$userInput -lt $minValidNumber) -or ([int]$userInput -gt $maxValidNumber)) -and ($userInput -notlike "f*") 

Answer 2

Nach 4 Stunden von Versuch und Irrtum (3 vor dem Stellen dieser Frage) fand ich schließlich die Antwort. int

Function PrintArrayAsGridWithDisplayNumber 
{ 
    param([string[]]$Array,[ValidateRange(1,24)][int]$ColumnCount) 

    [int]$arrDisplayNumCounter = 1 
    $GridSplat = @{ 
     InputObject = $Array|ForEach-Object { 
      New-Object psobject -Property @{'Value' = "$arrDisplayNumCounter - " + $_}; 
      $arrDisplayNumCounter++ 
     } 
     Property = 'Value' 
    } 

    if(-not $PSBoundParameters.ContainsKey('ColumnCount')) 
    { 
     $GridSplat['AutoSize'] = $true 
    } 
    else 
    { 
     $GridSplat['Column'] = $ColumnCount 
    } 

    $table = Format-Wide @GridSplat | Out-String 
    Write-Host $table 
}
