PowerShell equivalent of LINQ Any()?

Question

I would like to find all directories at the top level from the location of the script that are stored in subversion.

In C# it would be something like this

Answer 1

Unfortunately there is no equivalent in PowerShell. I wrote a blog post about this with a suggestion for a general purpose Test-Any function / filter.

function Test-Any() {
    begin {
        $any = $false
    }
    process {
        $any = $true
    }
    end {
        $any
    }
}
