c# - Regex for removing a specific BBCode from a string -

i'm trying write simple method removing specific bbcodes input string.

for example, have input of:

string input = "[b]hello world![/b]";

i want able do:

remove(input, "b");

and output of:

"hello world!"

regex isn't strong suit. i've managed piece next google:

public static string remove(string input, string code) { string pattern = string.format(@"\[{0}\].*?\[\/{1}\]", code, code); homecoming regex.replace(input, pattern, string.empty, regexoptions.ignorecase); }

unfortunately returns empty string given example.

can advise me on how can right regex desired output?

thanks

use simple regex: \[/?{0}\]

your regex removing whole string

your regex \[{0}\].*?\[\/{1}\] removing entire [b]...[/b] string. that's why getting empty string replacement.

what need remove [b] , [b]. in normal regex, expressed quite \[/?b\], slash made optional ?

in parametrized regex, \[/?{0}\] work.
