Concat two strings in powershell and supply as one parameter

Question

I am trying to concatinate two strings into a variable and then supple the new variable as a parameter in a command

$firstName = Read-Host -Prompt 'enter user first name'
$lastName = Read-Host -Prompt 'enter user last name'
$userAblevetsEmail = '' + $firstName + '.' + $lastName + '@company.com'
New-MsolUser -UserPrincipalName $userAblevetsEmail  -DisplayName $firstName + " " + $lastName -FirstName $firstName

I get the following error:

"New-MsolUser : A positional parameter cannot be found that accepts argument '+'."

Solution

Your code New-MsolUser -UserPrincipalName $userAblevetsEmail -DisplayName $firstName + " " + $lastName -FirstName $firstName is slightly off.

The info following -DisplayName cannot have spaces without being contained inside of something.

Here is an example fix:

New-MsolUser -UserPrincipalName $userAblevetsEmail -DisplayName "$firstName $lastName" -FirstName $firstName

You can simply use the variables directly inside quotation marks.

Yet another one: put them inside parentheses -DisplayName ($firstName + " " + $lastName)
