Powershell Clone Ordered Hashtable

Follow-up from this thread.

Issue

An ordered hashtable cannot be cloned.

Question

Is there an "easy" way to do this? I have indeed found some examples that seem overly complicated for such a "simple" task.

MWE

$a = [ordered]@{}
$b = $a.Clone()

Output

Method invocation failed because [System.Collections.Specialized.OrderedDictionary] does not contain a method named 'Clone'.

Solution

  • OrderedDictionary do not contain Clone method (see also ICloneable interface). You have to do it manually:

    $ordered = [ordered]@{a=1;b=2;c=3;d=4}
$ordered2 = [ordered]@{}
foreach ($pair in $ordered.GetEnumerator()) { $ordered2[$pair.Key] = $pair.Value }
