How to get hash table key which has specific value?

Question

I am having a hash table where Keys are being used based on value.

For ex.

    $ComponentTobeBuild=@{"ComponentNameX"="True";                           "ComponentNameXyz"="False";                           "SomeComponent"="False"} 

I would like to get the keys which are having values True. (I will pass the key to some other script as parameter).

I was trying like that , But i think some where i am missing as it is not listing the keys.

$($ComponentToBuild.Keys) | Where-Object { $_.Value -eq "True" } 

How to get the component Name which are having denoted as True? Also i would like to know whether hash table is a wise choice for this kind of work. Because I thought that Hash table will be mainly be used for processing the values.

Answer 1

$ComponentTobeBuild.GetEnumerator() | ? { $_.Value -eq "True" }

Hi this should work for what you want.

$ComponentTobeBuild=@{"ComponentNameX"="Test";                           "ComponentNameXyz"="False";                           "SomeComponent"="False"}                      Foreach ($Key in ($ComponentTobeBuild.GetEnumerator() | Where-Object {$_.Value -eq "Test"})) {$Key.name}
