What is the RegEx for this?

Question

0.00/5 (No votes)

See more:

I have various strings that may or may not contain '(_#)' where '#' is a number (can be multiple digits also.

Note sometimes it does not exist (the whole sequence), but if it does it is always at the beginning. I want to remove it for display purposes if it exists, so I thought RegEx would do this easily (well I know it does), but I am quite rusty.

Here are some string examples

(_0) Welcome
(_1) Information
(_2) Products
(_3) Help
Contact Info
Maps
Celery
Wild Wings
Deep Fried Pickles
(_4) Your thinking about BWW now

So all of these strings end up in some variable s and I want to rip out the '(_#)' if it exists and store the string in display.

Thank you in advance.

Solution 1

Try:

public static Regex regex = new Regex(
      @"^\(_\d*\)\s*",
    RegexOptions.IgnoreCase
    | RegexOptions.Multiline
    | RegexOptions.CultureInvariant
    | RegexOptions.IgnorePatternWhitespace
    | RegexOptions.Compiled
    );

string result = regex.Replace(InputText,"");

Get a copy of Expresso [^] - it's free, and it examines and generates Regular expressions. It generated the code once I had tested the regex!

I hope you don't mind that I opted for the literal string notation. I feel it's easier on the eyes. :)
Have my 5!

I agree - but Expresso always uses the long form, so I left it that way so as not to introduce a mistake.
