Get key of current value in hash table using powershell

Question

I'm having a problem, it looks simple but can't find a solution; I am iterating a hash table in PowerShell it looks like this:

foreach($tool in $otherTools.GetEnumerator() | Sort Name)
{
   #tried echo $tool.Name
   #tried echo $tool.Value
   #tried echo $tool.Key
}

but nothing above works. The reason is I want to use the switch statement inside by key.

HashTable looks like:

Name                           Value
----                           -----
One                           testone
Two                           TestTwo

Unclear question. What's not working? What output are you getting? Errors? — Frode F.

You are doing it right. Maybe you used something like echo "$tool.Key" which will output System.Collections.DictionaryEntry.Key. To fix that, you could either use echo "$($tool.Key)" or a format string:

$hashTable = @{
    One = 'testone'
    Two = 'TestTwo'
}

foreach ($tool in $hashTable.GetEnumerator() | sort Name)
{
    Write-Host ("Name: {0} Value: {1}" -f $tool.Key, $tool.Value)
}

Output:

Name: One Value: testone
Name: Two Value: TestTwo
