What is the easiest way in C# to trim a newline off of a string?

Question

I want to make sure that _content does not end with a NewLine character:

_content = sb.ToString().Trim(new char[] { Environment.NewLine });

Answer 1

How about just:

string text = sb.ToString().TrimEnd(null)

That will pull all whitespace characters from the end of the string -- only a problem if you wanted to preserve non-newline whitespace.
