Get variable value by its name stored in another variable in powershell

Question

I am newbie in powershell and have some problem.

Scenario

In my pipeline and scripts I have defined variable $myVar = 'someValue'. I store its name in $varName = 'myVar'.

Question

Is it possible to get myVar value by referencing $varName? I Tried something like: $($varName) but it returned only myVar, not 'someValue'

Try this:

(Get-Variable -Name $varName).Value

Or this: (as suggested by mklement0)

Get-Variable -Name $varName -ValueOnly

String.Empty

Nice; or, more directly: `Get-Variable -Name $varName -ValueOnly` – mklement0 Nov 27 '20 at 20:21

A bit more awkward answer.

$a = 'b'
$b = 1
(dir variable:).where{$_.name -eq $a}.value
1

Or

(dir variable:$a).value

Why not just `$a = 'b'` `$b = 1` `(dir variable:$a).value` `1` – Doug Maurer Nov 27 '20 at 20:04
@DougMaurer You're right. At first I tried `variable:$a` – js2010 Nov 27 '20 at 20:36
