c# - Multiply value selected in combobox by a number in label -


i trying work out how multiply selected value in combobox string value stored in label. have tried converting both values ints error keeps appearing:

unable cast object of type 'system.windows.controls.comboboxitem' type 'system.iconvertible'.

int quantity = convert.toint32(combobox3.selecteditem); int price = convert.toint32(label1.content); label2.content = quantity*price;

many thanks

i don't quite remember exact property of comboboxitem (i think text), need value of string rather whole object perform conversion. after that, use int's parsestring class method.
