You shouldn't be working with huge string
s at all.
If this represents a file's content, read it using File.ReadAllLines()
and take the array's Length
.
Otherwise, count the lines while you collect the data, not afterwards.
Dealing with a huge string
isn't doing the caches any favors.
And if you can't avoid it, I would consider:
static long LinesCount(string s) {return s.Length-s.Replace("\n","").Length;}
which was in one of my very first CP posts, a couple of years ago.

I am an engineer with a background in electronics, software and mathematics.
I develop technical software, both for embedded systems and for desktop equipment. This includes operating systems, communication software, local networks, image processing, machine control, automation, etc.
I have been using all kinds of microcontrollers and microprocessors (Intel 4004/8080/8051/80386/Pentium, Motorola 680x/680x0/ColdFire/PowerPC, Microchip PIC, Altera NIOS, and many more), lots of programming languages (all relevant assemblers, Fortran, Basic, C, Java, C#, and many more), and different operating systems (both proprietary and commercial).
For desktop applications and general development tools I have been using both UNIX systems and Mac/MacOS for many years, but I have switched to x86-based PCs with Windows, Visual Studio and the .NET Framework several years ago.
I specialize in:
- cross-platform development (making software that runs on diverse hardware/OS combinations)
- instruction set simulation
- improving software performance, i.e. making sure the software runs the job at hand in as short a time as possible on the given hardware. This entails algorithm selection, implementation design, accurate measurements, code optimisation, and sometimes implementing virtual machines, applying SIMD technology (such as MMX/SSE), and more.
