Dynamic variables in Powershell

Question

I am wondering if it is possible to reference a variable in powershell by concatonating two or more pieces of data. See example below...

$v0 = "My Var"
$v1 = "My Var2"

$suffix = 0

#THESE EXAMPLES BELOW (ALTHOUGH WRONG) WILL ILLUSTRATE WHAT WE ARE TRYING TO DO.

Write-Host $(v($suffix)) #ERROR
Write-Host $(v$suffix) #ERROR
Write-Host v$suffix # "v0"

I would like this script to output "My Var". I do not think this is possible since Powershell is using .NET which is not a dynamic language. Any ideas if this is possible?

I think in that example they are dynamically creating the name not pointing to a variable by putting together pieces of data — JBone

@JBone Think of variable, function, alias, and environment variables names as paths (similar to filename paths) in PS. You can refer 2 an item with this syntax: <provider drive>:<path name>. Get-psdrive will give you a list of <provider drive>s. Examples gi c:file.txt, gi variable:v0, gi env:path, etc. Similarly these: ${c:file.txt}, ${variable:v0}, ${env:path} also get an item. In last 2 you can omit braces. This illustrates paths but doesn't answer your question. For that u have 2 use provider specific cmdlets: get-variable and get-alias. They take names created by concatenation — Χpẘ
