Script to remove .vb files from a directory

I wrote a script to remove .vb code files when there are corresponding .cs files in a certain directory structure. But I felt like there were some extra statements that I had to put in there that didn't feel natural. Is there a better way to do this check and then action?

Specifically, having to do the foreach at the end didn't seem right to me. I also didn't know if there was a more PowerShell-y way to do the change extension and test-path.

ls . -include *.vb -recurse 
    | ? { $cs = [System.IO.Path]::ChangeExtension($_.FullName, ".cs"); Test-Path $cs } 
    | % { rm $_ -force }

You could combine expression vs. command mode in PowerShell, process only files (!$_.PSIsContainer) and use regex instead of ChangeExtension:

gci -include *.vb -Recurse |
    ? { (!$_.PSIsContainer) -and (Test-Path ($_.FullName -replace "\.vb$", ".cs") } |
    % { rm $_ -force }
