Updating hash table values in a 'foreach' loop in PowerShell

Question

I\'m trying to loop through a hash table and set the value of each key to 5 and PowerShell gives an error:

$myHash = @{}
$myHash[\"a\"] = 1
$myHash[\"b\"] =          


        

Answer 1

You have to get creative!

$myHash = @{}
$myHash["a"] = 1
$myHash["b"] = 2
$myHash["c"] = 3

$keys = @()
[array] $keys = $myHash.keys

foreach($key in $keys)
{
    $myHash.Set_Item($key, 5)
}

$myHash

Name                         Value
----                         -----
c                              5
a                              5
b                              5
