Say i have a text file that contains some computer names eg
pclist.txt
pc001
pc002
etc
I want to make sure that each pc has NO trailing invisible characters. Eg
pc001 must not have pc001<blank space><blank space>
What is the .net class to use ?

Trim() method on String class will do this.
PS C:\> " aaa","aaa " | %{ "[$_]" }
[ aaa]
[aaa ]
PS C:\> " aaa","aaa " | %{ "[$($_.trim())]" }
[aaa]
[aaa]

sorry i m not looking for a way to trim trailing characters.
Are there any functions to *determine* that a string contains trailing
characters ?

You can use -match to check for trailing whitespace:
get-content list.txt |% {if ($_ -match "\s$"){write-host "Entry $($_)
contains trailing whitespace."}}
