Once you create a hash table, it is easy for you to add new key-value pairs like this:
PS > $myHash = @{} PS > $myHash.Name = 'Tobias' PS > $myHash.ID = 12 PS > $myHash.Location = 'Hannover' PS > $myHash Name Value ---- ----- ID 12 Name Tobias Location Hannover
Use its Remove() method to remove a key from a hash table:
PS > $myHash.Remove('Location') PS > $myHash Name Value ---- ----- ID 12 Name Tobias
