How do you split multi-line string into lines?

I know this way

var result = input.Split("\n\r".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

looks a bit ugly and loses empty lines. Is there a better solution?

  • If it looks ugly, just remove the unnecessary ToCharArray call.

  • If you want to split by either \n or \r, you've got two options:

    • Use an array literal – but this will give you empty lines for Windows-style line endings \r\n:

      var result = text.Split(new [] { '\r', '\n' });
      
    • Use a regular expression, as indicated by Bart:

      var result = Regex.Split(text, "\r\n|\r|\n");
      
  • If you want to preserve empty lines, why do you explicitly tell C# to throw them away? (StringSplitOptions parameter) – use StringSplitOptions.None instead.
