NewLine replacement c#?

Question

I have a windows phone application. In the application I have a textbox whose acceptsreturn property is set to true.

What I want to do is create a string from the textbox and replace the new lines with a specific character, something like "NL"

I've tried the following but none of them worked.

string myString = myTextBox.Text.Replace(Environment.NewLine,"NL");
string myString = myTextBox.Text.Replace("\n","NL");

Are you sure it's the newline character you are after, and not `carriage return` - \r? Does `string myString = myTextBox.Text.Replace("\r","NL");` work? Environment.NewLine is usually `\r\n` on Windows for example, so you've tried \n and \r\n! — dash, Mar 05 '13 at 10:06
Why didn't it work? Was there an exception? Or was the output not formatted as you wanted? — psubsee2003, Mar 05 '13 at 10:07
well it didnt cause an exception, it just didnt work. newline didnt get replaced — user1924391, Mar 05 '13 at 10:08
string myString = myTextBox.Text.Replace("\r","NL"); worked! Thank you a lot, ive been searching for this the whole morning. I had no idea that the carriage return \r existed! — user1924391, Mar 05 '13 at 10:10

I'm not familiar with windows phone(or silverlight), but try to split with \r instead:

string myString = myTextBox.Text.Replace("\r","NL");

Yes that was the answer after all! Thanks! – user1924391 Mar 05 '13 at 10:11
Is this classed as duplicate? Is windows phone effectively silverlight? – Meirion Hughes Mar 05 '13 at 10:18

Consider replacing different types of line breaks to handle all the possibilities

string myString myTextBox.Replace("\r\n", "NL").Replace("\n", "NL").Replace("\r", "NL");

Use this code

var myString = myTextBox.Text.Replace("\r","NL");

This is for compatibility with every operating systems.

A question with a similar topic had a quite elegant answer you might consider interesting to use:

using System.Text.RegularExpressions;

myTextBox.Text = Regex.Replace(myTextBox.Text, @"\r(?!\n)|(?<!\r)\n", "NL");
