What is the best way to convert a string separated by return chars into a List?

Question

I need to often convert a \"string block\" (a string containing return characters, e.g. from a file or a TextBox) into List

No need to convert to your special sign:

List strings = str.Split(new string[] {Environment.NewLine}, StringSplitOptions.None).ToList();
strings.ForEach(s => s = s.Trim());
