This was too easy -- for me I m filtering out certain email items   I m writing my own custom email junk filter   With  r and or  n in the string it was wiping out all items instead of filtering   So  I just did filter   filter Remove   n   and filter   filter Remove   r     I m making my filter such that an end user can use Notepad to directly edit the file so there s no telling where these characters might embed themselves -- could be other than at the start or end of the string   So removing them all does it   The other entries all work but Remove might be the easiest   I learned quite a bit more about Regex from this post -- pretty cool work with its use here

If you are using multiple platforms you are safer using this method   value TrimEnd System Environment NewLine ToCharArray       It will account for different newline and carriage-return characters

s TrimEnd      The above is all I needed to remove   r n  from the end of my string   The upvoted answer seems wrong to me   Firstly  it didn t work when I tried  secondly  if it did work I would expect that s TrimEnd   r     n   would only remove either a   r  or a   n   so I d have to run it over my string twice - once for when   n  was at the end and the second time for when   r  was at the end  now that the   n  was removed
