If you want to support all kinds of newlines (CR, LF, CR LF) and don’t need blank lines, you can split on both characters and make use of the String.Split option that stops it from producing empty entries:

str.Split(ControlChars.CrLf.ToCharArray(), StringSplitOptions.RemoveEmptyEntries)

(This also produces an empty array if the input is empty.)

If you know you have consistent CR LF newlines and you want to preserve blank lines, you can split on the entire delimiter:

str.Split({ControlChars.CrLf}, StringSplitOptions.None)
