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

Use the Framework. The ReadLine() method has the following to say:

A line is defined as a sequence of characters followed by a line feed ("\n"), a carriage return ("\r") or a carriage return immediately followed by a line feed ("\r\n"). The string that is returned does not contain the terminating carriage return or line feed.

So the following will do the trick

_content = new StringReader(sb.ToString()).ReadLine();
