Looping Question with indexes - Powershell

Question

Hi,

I am trying to get a loop working for one order - I am having issues because the index of the array starts at 0

$null = For ($i=0; $i -le $OrderNumbers.count-1; $i++) 
{

}

I have tried using a temp variable to say if order numbers .count = 1 to set to two but then that loops through twice once for 0 and once for 1.

I am only wanting it to loop through once for one record.

Any help appreciated

This test does not seem to work at all

 $q = 0
    $t = 1
    $OrderNumbers = @(1,2)
    $OrderNumbers.count
    $x=1
    for ($y=0; $y -le $OrderInfo.count-1; $y++)
    {
        "yo"
        $x++
        $x
    }

Answer 1

$OrderNumbers = @(1,2) … $OrderInfo.count-1

In the array declaration you use name $OrderNumbers and in the for loop an other name $OrderInfo ; that don't work =>

$q = 0
$t = 1
$OrderNumbers = @(1,2,3,4);
Write-Host $OrderNumbers.count;
$x=1;
for ($y=0; $y -le $OrderNumbers.count -1; $y++)
{
    Write-Host "yo";
    $x++;
    Write-Host $x;
}

Answer 2

There's really no need for the For-loop.

$OrderNumbers = @(1,2)
$x=1
$OrderNumbers |
    ForEach-Object{
        Write-Host "OrderNumber: $_" -ForegroundColor Yellow
        "yo"
        $x++
        $x
    }
