Rules for counting with parentheses C# -

-

this question has answer here:

this mabey dumb question try count discount on price this:

newallavaror.pris = system.convert.todouble(            (1 - (clientkampanj.visakampanj(vara.produktnamn) / 100)) * vara.pris ).tostring();

it in reality (1-(20/100)*7.99), output 7.99 should 6,392..becuse orginal price 7.99... have tried move parentheses 1 then..

in wich order c# go thru parentheses, becuse should work right??

i'm pretty sure doing integer division here:

 (clientkampanj.visakampanj(vara.produktnamn) / 100)

so if have 20/100, result in 0 instead of expected 0.2 reminder truncated.

you need convert double, 1 of operands:

 (clientkampanj.visakampanj(vara.produktnamn) / 100.0)

since @scott pointed out other variables of type decimal, need convert 1 of operands type instead:

 (clientkampanj.visakampanj(vara.produktnamn) / 100.0m)

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
