Exclude list in PowerShell Copy-Item does not appear to be working

Question

I have the following snippet of PowerShell script:

$source = \'d:\\t1\\*\'
$dest = \'d:\\t2\'
$exclude = @(\'*.pdb\',\'*.config\')
Copy-Item $source $dest -R

As comments format code badly I'll post as answer but it's just an addition to @landyman's answer. The proposed script has a drawback - it will create double-nested folders. For example for 'd:\t1\sub1' it will create empty directory 'd:\t2\sub1\sub1'. That's due to the fact that Copy-Item for directories expects parent directory name in -Destination property not directory name itself. Here's a workaround I found:

Get-ChildItem -Path $from -Recurse -Exclude $exclude | Copy-Item -Force -Destination {
  if ($_.GetType() -eq [System.IO.FileInfo]) {
    Join-Path $to $_.FullName.Substring($from.length)
  } else {
    Join-Path $to $_.Parent.FullName.Substring($from.length)
  }
}
