Concatenate string with object in Powershell

Question

Currently I want to get a list of active user on Windows 10 using Powershell.
After some searching I found this helps:

Get-LocalUser | Where-Object -Property Enabled -eq True

And here is the output:

Name       Enabled Description
----       ------- -----------
User_1     True               
User_2     True

I just want to concatenate strings to a list of values of Name column from above, which will be like below:

Active user(s): User_1, User_2

Do you have any idea how I can do that? I'm just a non-tech guy trying to learn some useful command so forgive me if this is a basic to you.

You can do the following:

# Retrieve the name values
$Users = Get-LocalUser |
    Where-Object Enabled -eq True | Select-Object -Expand Name
# Create the output string
"Active user(s): {0}" -f ($Users -join ', ')

Using -Expand (or -ExpandProperty) from Select-Object, the target property's value is returned rather than the object that contains the property.

-f is the string format operator. It uses substitution for the {position} syntax. The -join operator creates a string from a list with , as the delimiter.
