Dynamically create variables in powershell

Question

I'm attempting to figure out how to create a new variable each time a loop runs. Something along the lines of

for ($i=1; $i -le 5; $i++)
{
    $"var + $i" = $i
    write-host $"var + $i
}

Use New-Variable and Get-Variable (mind available options including scopes). E.g.

for ($i=1; $i -le 5; $i++)
{
    New-Variable -Name "var$i" -Value $i
    Get-Variable -Name "var$i" -ValueOnly
}

perfectly valid answer. I would add that anytime that I need to do something like this, I prefer to use a hash table. – EBGreen Oct 22 '12 at 16:19

I also prefer hashtables. Still, there are some (rare) cases where only these cmdlets help. – Roman Kuzmin Oct 22 '12 at 16:27

An example is in a psake block like the properties block where you need to do something REALLY dynamic. – George Mauer Jul 18 '13 at 20:30
