Best way to split string into lines

Question

How do you split multi-line string into lines?

I know this way

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

Slightly twisted, but an iterator block to do it:

public static IEnumerable Lines(this string Text)
{
    int cIndex = 0;
    int nIndex;
    while ((nIndex = Text.IndexOf(Environment.NewLine, cIndex + 1)) != -1)
    {
        int sIndex = (cIndex == 0 ? 0 : cIndex + 1);
        yield return Text.Substring(sIndex, nIndex - sIndex);
        cIndex = nIndex;
    }
    yield return Text.Substring(cIndex + 1);
}

You can then call:

var result = input.Lines().ToArray();
