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

You can give one sequential key as you add elements:

$hashtable = @{}
$hashtable[$hashtable.count] = @("Switzerland", "Bern")
$hashtable[$hashtable.count] = @("Spain", "Madrid")
$hashtable[$hashtable.count] = @("Italy", "Rome")
$hashtable[$hashtable.count] = @("Germany", "Berlin")
$hashtable

Then, you can get elements sorted by the key:

echo "`nHashtable keeping the order as they were added"
foreach($item in $hashtable.getEnumerator() | Sort Key)
{
    $item
}
