Powershell equivalent of a conditional operator?

Question

Hi,
I've got a small snippet of Powershell code that works perfectly well, but I'd like to make it better. here it is:
if ($discoveredIssues.Length -gt 0){
$returnHash += @{"IsBatchValid"=$false}
else{
$returnHash += @{"IsBatchValid"=$true}
I don't like the fact that the string literal "IsBatchValid" exists in two places as there's always the chance that someone could change it one place and not the other (very minor quibble, I know).
I was wondering if there was a way to write this such that I don't have the if...then...else. I tried to do this:
$returnHash += @{"IsBatchValid"={if ($discoveredIssues.Length -gt 0){$false}else{$true}}}
but that doesn't work. It just returns "if ($discoveredIssues.Length -gt 0){$false}else{$true}}" rather than the actual result of that expression. I was hoping there might be something like C#'s conditional operator so that I could do something
like this:
    $discoveredIssues.Length -gt 0 ? $false : $true
but sadly not.
Any ideas how I can achieve this? I suspect there isn't a way, but it'd be nice if there were.
thanks
Jamie

Answer 1

$returnHash.IsBatchValid = $discoveredIssues.Length -gt 0
Oh nice. Didn't quite work. Powershell ISE complained:
But it prompted me to go away and change it to this:
$returnHash += @{"IsBatchValid"=$discoveredIssues.Length -eq 0}
which I suppose would have been obvious had I bothered to pay any attention to what I was doing. Always pays to have someone else put eyes on something. thanks mjolinor.
Glad to help.
It wasn't obvious from the code whether $returnHash already exists or not.  I was assuming it did:
$returnHash = @{}
$returnHash.IsBatchValid = $discoveredIssues.Length -gt 0
$returnHash
Name Value
IsBatchValid False
[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "
