Put value from an array to another array specific column

I’m trying to put values from an array to another array on a specific column.

The context is to see which user was logged at some date.
The Array1 contains the date and the Array2 contains the information about the users.

Array1:

Date
06/01/2022 12:00:00
06/01/2022 12:00:02
06/01/2022 12:00:03

Array2:

IP             Users       DateHour
192.168.1.1    Snake       
192.168.1.3    Mario
192.168.1.4    John Doe

I need to append the DateHour column (Array2) dynamically with the date from the Date column (Array1)

Everytime i’m trying with a for loop or a foreach loop it don’t append correctly and I don’t understand why.

Here is an exemple of what I’ve done:

for ($i=0 ; $i -lt $Array1.Count; $i++){
    for ($y=0 ; $y -lt $Array2.Count; $y++){
    $Array2.Datehour[$y] += $Array1.Date[$i]
}
}

From my understanding, the Array2.Datehour column will append, but it take long to finish and nothing appear.

Thanks for your help.

>Solution :

Assuming the two arrays are aligned (index N of the first array corresponds to index N in the second array), you only need 1 for loop:

for($i = 0; $i -lt $array1.Count; $i++){
  $array2[$i].Datehour = $array1[$i]
}

Note that we index into $array2, not $array2.Datehour – the latter is a "synthetic array" made up of enumerated property values, and assigning to it won’t modify the underlying array item.
