powershell joinging strings without a space
Hi, I am still learning PowerShell and attempting to resolve a problem I found when exploring the functionality of the ForEach-Object Cmdlet. When I attempt to join the 2 variables a space appears in between them and I can't seem to get rid of it no matter what I try. I think its something to do with the Output field separator but after trying several different tactics to change it I am at a loss. I have noticed if I use a txt file instead of a .csv & Get-Content the problem does not occur but using .txt files would limit the use's I am envisioning for ForEach-Object. Can anyone offer a solution preferably with an explanation of why and how to manipulate variables in the loop? thanks in advance
$var1 = Import-Csv -Path D:\Book1.csv
$Ending = "@Domain.com"
$Var1 | ForEach-Object {
Write-Host $_.Name,$Ending
}
$var1 = Import-Csv -Path D:\Book1.csv
$Ending = "@Domain.com"
$Var1 | ForEach-Object {
Write-Host $_.Name,$Ending
}

Sorry take that back I just made a school boy syntax error. Thanks for the response's. Neilsr I like your phrasing but Raheman Mohammed Abdul's answer looks far more easy to understand when learning. Could you point me to the how and why of your syntax? thanks
OK, using $variables inside a string is normally just a case of doing "$variablename" and the contents of the variable will be used in the string.
However when you are using an object property, i.e. $_.name , where $_ is an object and .name is a property of the object, you need to use the "$($variable.property)" method. the $() around the variable and property just instruct powershell to treat the contents between the $( and the ) as a whole variable expression.
Without the $() around it, "$variable.property" would be evaluated as $variable followed by the litteral text of ".property"
Hope thats clear?

Sorry and finally would this work in a loop like this:
$var1 = Import-Csv -Path D:\Book1.csv
$Ending = "@Domain.com"
$Var1 | ForEach-Object {
New-ADUser -Name $_.Name -UserPrincipalName $_.Name,$Ending -Separator ''
}
# Or using the 2nd example
$var1 = Import-Csv -Path D:\Book1.csv
$Ending = "@Domain.com"
$Var1 | ForEach-Object {
New-ADUser -Name $_.Name -UserPrincipalName "$($_.name)$ending"
}
$var1 = Import-Csv -Path D:\Book1.csv
$Ending = "@Domain.com"
$Var1 | ForEach-Object {
New-ADUser -Name $_.Name -UserPrincipalName $_.Name,$Ending -Separator ''
}
# Or using the 2nd example
$var1 = Import-Csv -Path D:\Book1.csv
$Ending = "@Domain.com"
$Var1 | ForEach-Object {
New-ADUser -Name $_.Name -UserPrincipalName "$($_.name)$ending"
}
The first would not no but the second yes.
Once you understand the concept of using "$($var.prop)" you can build complex strings quick and easily.

Thanks for the great explanation and the extra help Neilsr. I am getting it now
You could have an object called $User with properties of firstname, lastname and Domain for example and the email address would be.....
"$($User.firstname).$($Use
The . and the @ between the $($) pairs are literal chars so will get, for example.
Fred.Blogs@SomeDomain.com
"$($User.firstname).$($Use

Fred.Blogs@SomeDomain.com
Oops zero points even I posted the correct answer and the first one to post

Sorry Raheman I know your answer was correct but Neilsr really went the extra mile with a great explanation and his way is far more flexible
write-host $_.Name,$Ending -Separator ''
