How to verify version format in powershell script?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
So I am trying to verify if a provided version number is valid or not in powershell with the following code:
$ParsedVersion=''
if ([System.Version]::TryParse("1.2.3.43", [ref]$ParsedVersion)) {
Write-Host ("valid version")
}
else {
Write-Host ("invalid version")
}
but I keep getting the error Exception calling "TryParse" with "2" argument(s): "Cannot convert value "" to type "System.Version". Error: "Version
string portion was too short or too long.""
I tried lots of different ways but still no luck. I am wondering if there exists a right way to do this? Appreciate your help!
