How can I dynamically call a variable in PowerShell?

Question

I am creating a new variable name by combining existing variables, however, I cannot find a way to reference the new variable names dynamically through using my existing variables.

$count = 1
New-Variable -Name "Jobname$Count"

I am expecting to get "Jobname1" when I resolve dynamically with $JobName$Count.

I have tried different combinations of referencing the variable but none of them worked:

$JobName$($Count)
$JobName"$Count"
$JobName"$($Count)"
$JobName"($Count)"

How can I achieve this?

You already know how to dynamically create a new variable, either by using New-Variable or Set-Variable. If you want to dynamically get your variable you can either use Get-Variable or $ExecutionContext.SessionState.PSVariable.Get(..) or a much easier way would be using -PassThru:

$count = 1
$var = New-Variable -Name "Jobname$Count" -Value 'example' -PassThru
$var

Name                           Value
----                           -----
Jobname1                       example

Get-Variable "Jobname$Count"

Name                           Value
----                           -----
Jobname1                       example

$ExecutionContext.SessionState.PSVariable.Get("Jobname$Count")

Name                           Value
----                           -----
Jobname1                       example
