c# - regex query implementation -

i trying check search box , query works has couple of problems.

// ================================= var check = new regex("[^a-za-z]"); match m = check.match(searchquery); if (m.equals(check) != true) { pnl_message.visible = true; pnl_message.cssclass = "messagetable"; lbl_message.text = " * letters allowed"; }

the if statement equals says suspicious comparing ! works! thing goes in if statement no matter set look too.

how should querying searchquery?

your equals comparing match regex - they're different classes, it's never true, , go if block.

you want if (m.success) - checks whether value returned check.match(...) successful match (i.e. input contained non-letter) or not.
