Is the "Contains" Delphi string helper case sensitive? -


delphi xe3 introduced contains string helper function, help-file/wiki not state whether case sensitive or not?

yes case sensitive.

quick test:

showmessage('test'.contains('t').tostring(tuseboolstrs.true));

returns false

use tolowerinvariant or toupperinvariant compare case insensitive:

showmessage('test'.tolowerinvariant.contains('t').tostring(tuseboolstrs.true));
