Re: A little help with regular expressions

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Thanks for the responses Kevin and Jon,
I wanted to do some benchmarking to see how fast I could get the regex to work. It's always nice to be able to compare different solutions to a problem before settling with one.
I'm using it in a HttpModule to redirect urls, so I want it to be as fast as possible.
I'm gonna run some benchmarks on the solution I have and see how I can optimize it.

Best regards,
Mats Lycken

Hi Mats,

I agree with Larry that using IndexOf in String class is enough in this scenario. Also, you don't need to worry about the performance for it. I think it'll be faster than RegEx, because it will parse the whole string according to RegEx schema, which makes it slower.
