How can I remove “\r\n” from a string in C#? Can I use a regular expression?

Question

I am trying to persist string from an ASP.NET textarea. I need to strip out the carriage return line feeds and then break up whatever is left into a string array of 50 chara

Answer 1

This splits the string on any combo of new line characters and joins them with a space, assuming you actually do want the space where the new lines would have been.

var oldString = "the quick brown\rfox jumped over\nthe box\r\nand landed on some rocks.";
var newString = string.Join(" ", Regex.Split(oldString, @"(?:\r\n|\n|\r)"));
Console.Write(newString);

// prints:
// the quick brown fox jumped over the box and landed on some rocks.
