Does PowerShell support constants?

I would like to declare some integer constants in PowerShell.

Is there any good way to do that?

Solution

  • Use

    Set-Variable test -Option Constant -Value 100

    or

    Set-Variable test -Option ReadOnly -Value 100

    The difference between "Constant" and "ReadOnly" is that a read-only variable can be removed (and then re-created) via

    Remove-Variable test -Force

    whereas a constant variable can't be removed (even with -Force).

    See this TechNet article for more details.
