copied!<p>You don't need LINQ - but you could 'enumerate' and use lambda to make it more generic...<br> (though not sure if any of this makes sense) </p> <pre><code>static IEnumerable<string> Split(this string text, Func<char?, char?, char, int?> shouldSplit) { StringBuilder output = new StringBuilder(); char? before = null; char? before2nd = null; foreach (var c in text) { var where = shouldSplit(before2nd, before, c); if (where != null) { var str = output.ToString(); switch(where) { case -1: output.Remove(0, str.Length -1); yield return str.Substring(0, str.Length - 1); break; case 0: default: output.Clear(); yield return str; break; } } output.Append(c); before2nd = before; before = c; } yield return output.ToString(); } </code></pre> <p>...and call it like this e.g. ... </p> <pre><code> static IEnumerable<string> SplitLines(this string text) { return text.Split((before2nd, before, now) => { if ((before2nd ?? 'A') == '\r' && (before ??

'A') && char.IsUpper(now)) return 0; // split on 'now' if (char.IsUpper(before2nd ?? 'a') && char.IsUpper(before ?? 'a') && char.IsLower(now)) return -1; // split one char before return null; // don't split }); } </code></pre> <p>...and somewhere... </p> <pre><code> var text = "ToSplitOrNotToSplitTHEQuestionIsNow"; var words = text.SplitOnCase(); foreach (var word in words) Console.WriteLine(word); text = "To\r\nSplit\r\nOr\r\nNot\r\nTo\r\nSplit\r\nTHE\r\nQuestion\r\nIs\r\nNow"; words = text.SplitLines(); foreach (var word in words) Console.WriteLine(word); </code></pre> <p>:)</p>
