.net - Deep copying a PSObject -

i have powershell script in following

$somepsobjecthashtables = new-object hashtable[] $somepsobject.length; $somepsobjects = import-csv $csvpath 0..($somepsobject.length - 1) | foreach-object {     $i = $_;     $somepsobjecthashtables[$i] = @{};     $somepsobject[$_].psobject.properties | foreach-object {         $somepsobjecthashtables[$i][$_.name] = $_.value;     } } 

i need because want make several distinct copies of data in csv perform several distinct manipulations. in sense i'm performing "inner join" on resulting array of psobject. can iterate through $somepsobjecthashtables foreach-object , call hashtable.clone() on each member of array. can use new-object psobject -property $somehashtable[$i] deep copy of psobject.

my question is, there easier way of making deep copy, without intermediary hashtable?

for getting deep copies can use binary serialization (assuming data serializable; case data come csv):

# original data $data = import-csv ...  # serialize , deserialize data using binaryformatter $ms = new-object system.io.memorystream $bf = new-object system.runtime.serialization.formatters.binary.binaryformatter $bf.serialize($ms, $data) $ms.position = 0 $data2 = $bf.deserialize($ms) $ms.close()  # use deep copied data $data2
