Fastest way to replace multiple strings in a huge string

Question

I m looking for the fastest way to replace multiple (~500) substrings of a big (~1mb) string. Whatever I have tried it seems that String.Replace is the fastest way of doing

Answer 1

You probably won't get anything faster than String.Replace (unless you go native) because iirc String.Replace is implemented in CLR itself for maximum performance. If you want 100% performance, you can conveniently interface with native ASM code via C++/CLI and go from there.
