Powershell scripting Assistance : Testing Variable Creation

Experts,

What is the easiest way to acomplish the following:

I am looking at turning the following working code into a reusable function.

Function invoke-varcheck2(){
        if ($services.count -gt "200"){
            write-host "Check was successful"
        }else {
            write-host "Variable was not created successfully"
        }
    }
    . invoke-varcheck2

Open in new window

Here was my attempt that was less than successful :

Function invoke-varcheck($varname, $count){
    write-host "Attempting to Test Variable $varname"
        if (($+"$(($varname).count)" -gt $count){ 
            write-host "Check was successful"
        }else {
            write-host "Variable was not Created Successfully"
        }

}
invoke-varcheck -varname services -count 200

Open in new window

Where did I go wrong with this?

I do not sure if I well understand want you need, but you are already consider to use the cmdlet Get-Variable:

try
{
$null = Get-Variable -Scope Global -Name VariableName -ErrorAction Stop
$variableExists = $true
}
catch
{
$variableExists = $false
}

@Ermanno,

Thanks for the reply, get-variable would indeed tell me if the variable exists, but I need to go deeper than that and get an exact count of what is inside it in order to verify validity of the data.

Get-Variable can also return an object that match the name of a variabile that you specify... so you can then analize the object

Can you specify more better your target?
