Removing carriage return and new-line from the end of a string in c#
C#StringNewlineCarriage ReturnC# Problem Overview
How do I remove the carriage return character (\r)
and the new line character(\n)
from the end of a string?
C# Solutions
Solution 1 - C#
This will trim off any combination of carriage returns and newlines from the end of s
:
s = s.TrimEnd(new char[] { '\r', '\n' });
Edit: Or as JP kindly points out, you can spell that more succinctly as:
s = s.TrimEnd('\r', '\n');
Solution 2 - C#
This should work ...
var tst = "12345\n\n\r\n\r\r";
var res = tst.TrimEnd( '\r', '\n' );
Solution 3 - C#
String temp = s.Replace("\r\n","").Trim();
s
being the original string. (Note capitals)
Solution 4 - C#
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.
Solution 5 - C#
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).
Solution 6 - C#
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.

For us VBers:
TrimEnd(New Char() {ControlChars.Cr, ControlChars.Lf})
Solution 8 - C#
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+", " ");
Solution 9 - C#
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.
Solution 10 - C#
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

This is what I got to work for me.
s.Replace("\r","").Replace("\n","")
Solution 12 - C#
varName.replace(/[\r\n]/mg, '')
