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

I recommend the following solution:

<#
.SYNOPSIS 
   Tests if any object in an array matches the expression

.EXAMPLE
    @( "red", "blue" ) | Where-Any { $_ -eq "blue" } | Write-Host
#>
function Where-Any 
{
    [CmdletBinding()]
    param(
        [Parameter(Mandatory = $True)]
        $Condition,

        [Parameter(Mandatory = $True, ValueFromPipeline = $True)]
        $Item
    )

    begin {
        [bool]$isMatch = $False
    }

    process {
      if (& $Condition $Item) {
          [bool]$isMatch = $true
      }
    }

    end {
        Write-Output $isMatch
    }
}

# optional alias
New-Alias any Where-Any
