Took some playing around but I think this will work for you.
$array = "dog","cat","bird"
Foreach ($animal in $array) {
$animal
[array]::IndexOf($array,$animals)
}

Yes, that could work too. But that still requires that I initialize $idx and
increment it. What I was trying to find out is if there was a built in
mechanism where I could call something like "$ForEach.CurrentPosition" to help
identify what iteration loop I was on without needing to initialize and
increment an index variable.
Thanks,

Hmmm isn't that when you use the 'For' not 'foreach'
$arrAnimals = @("dog", "cat", "horse", "snake")
for (0; $idx -le $arrAnimals.length ;$idx++)
{
Write-Host ("Loop count: " + $idx)
Write-Host $arrAnimals[$idx]
}

Thanks for responding.
I am able to access the array value at a specific index. So in the example
below, I am able to successfully access the letter "c" if I use
"$arrLetters[2]".
However, what I would like to do is be able to identify what iteration loop
number the script is currently processing from within the foreach loop using a
built in method without needing to manually create and increment a counter
variable.
One example of where I would like to use this is:
$arrAnimals = @("dog", "cat", "horse", "snake")
foreach ($strAnimal in $arrAnimals)
{
Write-Host ("Loop count: " + <ForEachLoopCounter>)
Write-Host $strAnimal
}
Is there a built in method to determine what the <ForEachLoopCounter> is
without needing to create a counter variable and increment it manually on each
iteration?
Thanks,

I'm most likely wrong but wouldnt this give you C on index 0.
$strLetter [2]
@ the beach now ;) but will check it when I get home. PowerGUI gives you this
info easy when debuging

Is there an elegant way to get the current position in a ForEach loop without

For example, if I have the code below:
$arrLetters = @("a", "b", "c", "d")
foreach ($strLetter in $arrLetters)
{
Write-Host $strLetter
}
In this example, if the loop reaches "c", is there some built in method to
discover that the current iteration loop is # 2 (or #3 if the index starts at 1
instead of 0).
It's not necessarily a problem to initiate a "counter" variable, but I was just
curious to know if there is a cleaner way.
I am using PowerShell 3 in case that helps.
Thanks!
