Create a new PowerShell string containing defined substrings - string

Question

I've found myriad methods to retrieve data FROM a string with substrings, but what I want to do is create a new string that contains substrings. The reason for this is that I want to pass that string to a CSV through the Export-CSV cmdlet. This is in a PowerShell Forms created app.
So the plan would be to
1). Read the contents of each text box:
(e.g. $endusername.text $endusernumber.text $locationname.text)
2). Store those into a new string with substrings
($formoutput.endusername $formoutput.endusernumber $formoutput.locationname)
3). Output the string to a .CSV
Export-CSV -InputObject $formoutput "c:\output\formoutput.csv"
Basically, if I take any existing cmdlet (say, Get-Mailbox), store its output as a string, and then pass that string through the Export-CSV in the way explained above, it performs exactly the way I like - creating a .CSV with each of the substrings as a column, and the contents of that substring in the appropriately headed column. I just want to be able to do that with a string containing substrings that I define.

I think you are confusing nomenclature a little bit. It sounds like what you want is a custom object not a string. Here is some pseudo-code to get you going in the right direction:
$formOutput = New-Object PsCustomObject -Property #{'EndUserName' = $endUserName.Text;
'EndUserNumber' = $endUserNumber.Text;
'LocationName' = $locatioName.Text}
$formOutput | Export-CSV .\FileName.csv -NoTypeHeader
