PowerShell Function Good Input

Just a little prompt function that checks for ‘Good Input’.

Function GoodInput{

  Param([System.Array]$InArr,[Switch]$Ceq)

  $GI = $FALSE

  While(!$GI){

    [String]$RH = Read-Host

    $InArr | Foreach{

      If($Ceq){

        If($RH -ceq $_){$GI = $TRUE}}

      Elseif($RH -eq $_){$GI = $TRUE}

    }

  }

  RETURN $RH

}

And an example of using it in the image below:

"Y or N not case sensitive";[String]$Test = GoodInput "Y","N"

"Y or N case sensitive";[String]$Test2 = GoodInput "Y","N" -CEQ
