Email Formatted Array - arrays

Question

I got a script that creates two arrays (each has 1 column and variable number of lines). I want to format these two arrays and e-mail it to an Outlook account. Code and sample data below.
$Values2 = #(Get-Content *\IdealOutput.csv)
$OutputLookUp2 = #()
foreach ($Value in $Values2) {
$OutputLookUp2 += $Excel.WorksheetFunction.VLookup($Value,$range4,3,$false)
}
$Excel.Workbooks.Close()
$Excel.Quit()
$EmailFrom = "sample#sample.com"
$EmailTo = "sample#sample.com"
$EmailBody = "$Values2 $OutputLookup2"
$EmailSubject = "Test"
$Username = "sample"
$Password = "sample"
$Message = New-Object Net.Mail.MailMessage `
($EmailFrom, $EmailTo, $EmailSubject, $EmailBody)
$SMTPClient = New-Object Net.Mail.SmtpClient `
("smtp.outlook.com", portnumber) #Port can be changed
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential `
($Username, $Password);
$SMTPClient.Send($Message)
Both $OutputLookUp2 and $Values2 are one column with variable number of lines.
Example:
$Outputlookup2 =
X1
X2
$Values2 =
Y1
Y2
I would like the output to the body of the e-mail to be:
X1 Y1
X2 Y2
And I would like to avoid HTML as it will be sent via text as well.

Answer 1

Assuming my interpretation is correct this seems simple enough. For every $Values2, which is just a line from a text file, find its similar value in the open spreadsheet. You are have the loop that you need. Problem is you are building the item lists independent of each other.
$Values2 = #(Get-Content *\IdealOutput.csv)
$OutputLookUp2 = #()
foreach ($Value in $Values2){
$OutputLookUp2 += "$Value $($Excel.WorksheetFunction.VLookup($Value,$range4,3,$false))"
}
Now $OutputLookUp2 should contain your expected output in array form.
If the array does not work you could also just declare it as a string and the add newlines as you are building it. You will notice the "`r`n" at the end of the string.
$Values2 = #(Get-Content *\IdealOutput.csv)
$OutputLookUp2 = ""
foreach ($Value in $Values2){
$OutputLookUp2 += "$Value $($Excel.WorksheetFunction.VLookup($Value,$range4,3,$false))`r`n"
}
In both example you can just flip the order of the $value and the lookup easy. If you need a header you can add that when you declare $OutputLookUp2.
There is always room for improvement
If you want to take this a little further in the direction that Ansgar Wiechers was eluding to...
$OutputLookUp2 = Get-Content *\IdealOutput.csv | ForEach-Object{
"$_ $($Excel.WorksheetFunction.VLookup($_,$range4,3,$false))"
} | Out-String
