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

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

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).

This should work ...

var tst = "12345\n\n\r\n\r\r";
var res = tst.TrimEnd( '\r', '\n' );

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.

string k = "This is my\r\nugly string. I want\r\nto change this. Please \r\n help!";
k = System.Text.RegularExpressions.Regex.Replace(k, @"\r\n+", " ");

This is what I got to work for me.

s.Replace("\r","").Replace("\n","")

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.

String temp = s.Replace("\r\n","").Trim();

s being the original string. (Note capitals)

For us VBers:

TrimEnd(New Char() {ControlChars.Cr, ControlChars.Lf})

varName.replace(/[\r\n]/mg, '')                                              

I use lots of erasing level

String donen = "lots of stupid whitespaces and new lines and others..."

//Remove multilines
donen = Regex.Replace(donen, @"^\s+$[\r\n]*", "", RegexOptions.Multiline);
//remove multi whitespaces
RegexOptions options = RegexOptions.None;
Regex regex = new Regex("[ ]{2,}", options);
donen = regex.Replace(donen, " ");
//remove tabs
char tab = '\u0009';
donen = donen.Replace(tab.ToString(), "");
//remove endoffile newlines
donen = donen.TrimEnd('\r', '\n');
//to be sure erase new lines again from another perspective
donen.Replace(Environment.NewLine, "");

and now we have a clean one row

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.
