c# - 选中 CheckBox 时如何添加整数值？

Question

我希望在选中复选框时将值添加到整数 (int priceTotal)。该练习用于在网络表单中订购披萨。我希望能够根据选择的尺寸和浇头添加到总价中。

int priceTotal = 0;

if (smallPizzaCheck.Checked) 
{
    priceTotal + 10;
}
else if (mediumPizzaCheck.Checked) 
{
    priceTotal + 13;
}

//Et cetera, et cetera

orderTotal.Text = Convert.ToString(priceTotal);

Answer 1

int priceTotal = 0;

  if (smallPizzaCheck.Checked) 
 {
  priceTotal = priceTotal + 10;
 }

 else if (mediumPizzaCheck.Checked) 
 {
 priceTotal = priceTotal + 13;
 }

 //Et cetera, et cetera

 orderTotal.Text = Convert.ToString(priceTotal);

Just try this....whenever check box checked...the price total added..again and again... so you can sum into (priceTotal value) and display into textbox name("orderTotal.Text")
