Delete value from hashtable in powershell

Question

I want to delete a specific value from hashtable.

The table looks like this:

Name                           Value                                                                                                                                             
----                           -----                                                                                                                                             
column                         {test, test2}    

How can I delete the "test2" value?

I tried the following:

$myhashtable.remove("test2")

which unfortunately does not work.

Could someone help me with this? Thanks!

The example that you provided looks like a hashtable of hashtables. So you would need to do:

$myhashtable['column'].Remove('test2')

If it is a hashtable where the value is an array, then you would need to do this:

$myHashTable['column'] = ($myHashTable['column'] | ?{$_ -ne 'test2'})
