Hashtables and key order

Question

Is there a way to keep the order of keys in a hashtable as they were added? Like a push/pop mechanism.

Example:

$hashtable = @{}

$hashtable.Add(\"Sw         


        

Answer 1

Here is a simple routine that works for me.

function sortedKeys([hashtable]$ht) {
  $out = @()
  foreach($k in $ht.keys) {
    $out += $k
  }
  [Array]::sort($out)
  return ,$out
}

and the call to use it

forEach($k in (& sortedKeys $ht)) {
  ...
}
