Thanks Daniel! Yes, that will work for the condition case below, but if there
happens to be duplicate entries in the array, this will not work. So extending
your example below for instance, the following will not work correctly:
$array = "dog","cat","bird","dog"
Foreach ($animal in $array) {
$animal
[array]::IndexOf($array,$animal)
}
Since the results will produce:
dog
0
cat
1
bird
2
dog
0
Thanks,

Without the typo. $animals should be $animal.

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.

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!
