c# - Keydown Eventhandler Process -

i trying process keydown event below code process first char of string , not able remove second char of string.

private void game_keydown(object sender, keyeventargs e) {     if(birdsarray[selectedindex].this_string.first()== (char)e.keydata)     {         birdsarray[selectedindex].this_string = birdsarray[selectedindex].this_string.remove(0, 1);         this.validate();     } } 

in below code birdsarray array of panels, this_string string type of string object in birdsarray.

the keydown event gives virtual key code of key pressed. keys.a if press a-key. tells key, not letter that's produced key. depends on active keyboard layout (it not in japan or russia example) , modifier keys down. shift being obvious example, producing either a or a. or alt which, when down, doesn't produce letter @ all.

so code work accident if first letter of string capitalized. you'll run out of luck when rest not. a not match a.

it pretty unclear me why need feature. consider keypress event instead. gives actual letter user sees on screen.
