How to dump the foreach loop output into a file in PowerShell?

Question

I have wrote the following script to read the CSV file to perform the custom format of output.

Script is below:

$Content = Import-Csv Alert.csv
forea

Write-Host writes to the console. That output cannot be redirected unless you run the code in another process. Either remove Write-Host entirely or replace it with Write-Output, so that the messages are written to the Success output stream.

Using a foreach loop also requires additional measures, because that loop type doesn't support pipelining. Either run it in a subexpression:

(foreach ($Data in $Content) { ... }) | Out-File ...

or assign its output to a variable:

$output = foreach ($Data in $Content) { ... }
$output | Out-File ...

Another option would be replacing the foreach loop with a ForEach-Object loop, which supports pipelining:

$Content | ForEach-Object {
  $First = $_.DisplayName
  $Second = $_.ComputerName
  ...
} | Out-File ...

Don't use Out-File inside the loop, because repeatedly opening the file will perform poorly.
