Getting the current hash key in a ForEach-Object loop in powershell

hashtable, powershell

Solution

I like to use `GetEnumerator()` when looping a hashtable. It will give you a property `value` with the object, and a property `key` with it's key/name. Try:

$myHash.GetEnumerator() | % { 
    Write-Host "Current hashtable is: $($_.key)"
    Write-Host "Value of Entry 1 is: $($_.value["Entry 1"])" 
}

Problem

I've got a hash table: ``` $myHash = @{ "key1" = @{ "Entry 1" = "one" "Entry 2" = "two" } "key 2" = @{ "Entry 1" = "three" "Entry 2" = "four" } } ``` I'm doing a loop through to get the objects: ``` $myHash.keys | ForEach-Object { Write-Host $_["Entry 1"] } ``` Works fine, but what can I use to figure out which of the keys of `$myHash` I'm in? `$_.Name` doesn't return anything. I'm stumped. Help?
