Regex problem
-
I need that Regex won't return match if the string starts with another substring, for example "abc". In detail, "
abcde" shouldn't match, but "abg", "gbc" and "afcgr" should match. I know the [^abcde] syntax that works for characters, but I couldn't figure out way for substrings. It is possible to do this with Regex? I need it to be done through Regex, not String class methods. Thanks. -

(abc.*)|(?a.*)You can use backtracking too, but i dont really understand it, the above way does the same, kinda :p top secret

See some screenshotsI think you missed the point. "abc" should not match. I want to match any combination of three characters, except the above sequence. I can do it as well with two chars. For example, if i want to match anything except "ab", i can use
(?:a[^b])|(?:[^a].). But when it comes to three or more characters, i find no way. Maybe I miss something. Thanks. -

Groups["good"].Success. As long as your precedence is correct, you can match and 'eleminate' alot of data at once. top secret
