powershell - How do I retrieve a HashTable key from a value? -

i have powershell hashtable contains set of key-value pairs (naturally). of hashtable values unique.

i retrieve hashtable key, based on value specify, using powershell.

another options:

• to iterate on hashtable keys , find key contains value:
  $hashtable.keys |? { $hashtable[$_] -eq $val }

• to iterate using getenumerator() function:

  $hashtable.getenumerator() | ?{ $_.value -eq $val } | %{ $_.key }
