Powershell string to var

Question

I've been struggling with this issue for a while and searched for hours but can't find it how to solve it

Problem: All I want is basically to get a string, and then use it as a variable name.

Example:

Eval('SomeText') = 'someinfo'

Which would out come like:

$SomeText (which contains 'someinfo')

Maybe a little bit hard to explain hope you guys understand it, it's probably something simple but I just don't know how to do this in PowerShell scripting.

$SomeText = 'someinfo' isn't working? I think I am misunderstanding this. Oh! Do you mean setting the name of the variable based on results of another operation? — James Ruskin

yes exactly setting the name of the variable based on the result of another operation (sorry for the language barrier) — Apollyon

All good - so, you can use Set-Variable to do this. Example: Set-Variable -Name (Eval('SomeText')) -Value 'someinfo' — James Ruskin

You can use Set-Variable to set a variable variable name, as shown below.

PS> Set-Variable -Name ($env:COMPUTERNAME) -Value "sometext"
PS> Get-Variable -Name ($env:COMPUTERNAME)

Name                           Value
----                           -----
jr-pc                          sometext

You can also refer to the variable with (in this case):

$($env:COMPUTERNAME)
