Regex to replace every newline

Question

I need to replace every newline character in a string with another character (say 'X'). I do not wish to collapse multiple newlines with a single newline!

PS: this regex replaces all consecutive newlines with a single newline but its not what I need.

Regex regex_newline = new Regex("(\r\n|\r|\n)+");

Solution 1

That will replace one or more newlines with something, not necessarily with a single newline -- that's determined by the regex_newline.Replace(...) call, which you don't show.

So basically, the answer is

 Regex regex_newline = new Regex("(\r\n|\r|\n)");   // remove the '+'
 // :
 regex_newline.replace(somestring, "X");

Solution 2

Just use the String.Replace method and replace the Environment.NewLine in your string. No need for Regex.
