Does powershell have associative arrays?

Question

I am writing a function that returns an id, name pair.

I would like to do something like

$a = get-name-id-pair()
$a.Id
$a.Name

like

Answer 1

#Define an empty hash
$i = @{}

#Define entries in hash as a number/value pair - ie. number 12345 paired with Mike is   entered as $hash[number] = 'value'

$i['12345'] = 'Mike'  
$i['23456'] = 'Henry'  
$i['34567'] = 'Dave'  
$i['45678'] = 'Anne'  
$i['56789'] = 'Mary'  

#(optional, depending on what you're trying to do) call value pair from hash table as a variable of your choosing

$x = $i['12345']

#Display the value of the variable you defined

$x

#If you entered everything as above, value returned would be:

Mike
