asp.net - Is it possible to turn off case insensitivity using pattern only? -


regex has set option ignorecase. possible turn off case insensitivity using pattern (like negation of (?i))?

in example below, find pattern result "abaaabbaab".

string pattern = "???"; string input = "aaaaaaaaaa"; var regex = new regex(pattern, regexoptions.ignorecase); var result = regex.replace(input, "b");

you can turn off options inline using - before option. e.g. negation of (?i) (?-i):

a minus sign (-) before option or set of options turns options off. example, (?i-mn) turns case-insensitive matching (i) on, turns multiline mode (m) off, , turns unnamed group captures (n) off.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
