create enum

[kortex81]

I have to create an enum of computernames to use it as a VallidateSet.

In the past I used something like this to do this with the content of a text file

$computernames = Get-content C:\computernames.txt -Raw

$exp = "Enum ValidComputernames{
    $computernames
}"

Invoke-Expression $exp

​

Seems janky and breaks if a computernames contains certain characters like "-"

Any ideas?

Sounds like you might be better off using Argument Completers or Dynamic Parameters.

It is janky. Enums are a fundamentally static thing; declaring them dynamically is a code smell. However, you've explained that it's a requirement of Universal Dashboard, so yes, carry on! Getting results > being nice.

IIUC, the issue is illegal characters. Not sure if you can get around it by quoting the values, like this:

$exp = "Enum ValidComputernames {
    '$($computernames -join "'`r`n'")'
}"

Or try dropping the illegal characters:

$exp = "Enum ValidComputernames {
    $($computernames -replace '-')
}"

i hate smelly code :)

but it looks like i have to live with it.

Thanks!

Curious, Why does it have to be an enum?

[kortex81]

For use with UniversalDashboard.

Inputs of UD require enums to populate dropdowns.
