I'm trying to figure out a way to determine which element in an array I am working with. Here's a simplified scenario:

I've got a 2000 line text file, and I am iterating over each line using a foreach of an array of the file contents. If the text file meets certain criteria, I want to output the line and the array element, eg if it is the 40th line of the file, I want to output that line 40 (array item 39+1) contains the text. Obviously I can use a counter and increment it each time the loop starts, but it seems to me that there should be some way of having PowerShell tell me which array element I am working with.

Any thoughts?

One-time bump

You can use a for loop:

$lines = Get-Content -Path "MyFile.txt"

for ($i = 0; $i -lt $lines.Length; $i++)
{
    Write-Host "Reading element $i ..."
   Write-Host $lines[$i]
}

Generally, use a for loop if you want to keep track of where you are in an array.

Here's what I found to do what I want:

$a = 'a','b','c'
[array]::IndexOf($a, 'b')

This will return "2"
