Concatenate multiple Variables/CSVs and export as one CSV file Powershell - csv

Question

For example,
I have CSV file and imported to powershell
$fullname = Import-Csv “fullname.csv”
$fullname
Output is
FullName
------------------
John Smith
Kevin Johnson
I have another CSV file and imported to
$Email = Import-Csv “Email.csv”
$Email
the output is
Email
-------
jhrjf#gmail.com
hheraf1010#gmail.com
I would like to concatenate this 2 variables and export to as one csv file, so I tried like this
$fullname = Import-Csv “fullname.csv”
$fullname
$Email = Import-Csv “Email.csv”
$Email
($fullname+$Email)|Export-Csv C:\fullnameandEmail.csv -NoTypeInformation
i also try like this
-join($fullname,$Email)|Export-Csv C:\fullnameandEmail.csv -NoTypeInformation
but it was not working,
I would like to make csv like below, how can I concatenate these 2 valuables?
FullName Email
--------- ----------
John Smith jhrjf#gmail.com
Kevin Johnson hheraf1010#gmail.com
Thank you so much

Answer 1

It's helpful to understand that the $fullname and $email objects you have in memory after importing a CSV are actually arrays of objects. Each object has one or more properties that represent the column values from the CSV.
You can loop through the objects in either of the arrays and use the Add-Member cmdlet to add a new property to each object.
The following code loops through the $email array and for each item, it adds a property with the Email value to the corresponding item in the $fullname array. It then exports that merged array to a CSV file.
$fullname = Import-Csv "fullname.csv"
$email = Import-Csv "Email.csv"
$i = 0
$email | ForEach-Object {
Add-Member -inputobject $fullname[$i] -name Email -value $_.Email -membertype NoteProperty;
$i++}
$fullname | Export-Csv -notype -path "C:\fullnameandEmail.csv"

Answer 2

So, for simplicity I would combine what the other two have suggested. Use a For loop, and then within the loop use Add-Member.
$fullname = Import-Csv “fullname.csv”
$Email = Import-Csv “Email.csv”
For($i=0;$i -lt $fullname.count;$i++){
$FullName[$i] | Add-Member 'Email' $Email[$i].email
}
$FullName | Export-CSV -NoType Output.csv

Answer 3

$names = Import-Csv "fullname.csv"
$emails = Import-Csv "email.csv"
for ( $n = 0; $n -lt $names.Count; $n++ ) {
New-Object PSObject -Property #{
"FullName" = $names[$n].FullName
"Email" = $emails[$n].Email
} | Select-Object FullName,Email
}
