How to change output of powershell command response?

Question

PowerShell

I query computers in the domain using the command

Get-WMIObject -Class Win32_ComputerSystem -Computer name |Select-Object Username

And everything would be fine, but it returns the answer as a column of the table

. How to output as a single line?
The matter is that I substitute names of computers a cycle and in passing I collect some more values. Further, I write these values ​​​​into a txt file, separated by commas, and this table header breaks everything.
