Removing carriage return and new-line from the end of a string in c#

Question

How do I remove the carriage return character (\\r) and the new line character(\\n) from the end of a string?

Answer 1

If there's always a single CRLF, then:

myString = myString.Substring(0, myString.Length - 2);

If it may or may not have it, then:

Regex re = new Regex("\r\n$");
re.Replace(myString, "");

Both of these (by design), will remove at most a single CRLF. Cache the regex for performance.
