I've compared your favorite with seven alternatives:static long LinesCount(string s) { long count = 0; int position = 0; while ((position = s.IndexOf('\n', position)) != -1) { count++; position++; // Skip this occurance! } ...

It seems like an obvious requirement, but the .NET framework will not count occurrences of a character in a string. It's easy to do, but which way is the quickest?
How about using the extension method: return s.Count(c => (c == '\n'));
Hello! Great tip!What do you think about this extension method:public static class StringExtension{ public unsafe static long LineCount(this string s) { long lineCount = 1; fixed (char* pchar = s) { char* p = pchar; for (; *p...

Great analysis!I found out that Regex can be accelerated by a factor of about two.Instead of new Regex(@"\n", RegexOptions.Compiled|RegexOptions.Multiline);you can speed up by using:new Regex(@"^.*?$", RegexOptions.Compiled|RegexOptions.Multiline);But admittedly, nothing beats...
