两个c#单选按钮，编码相同，但一个给出准确结果，另一个不'；T

两个c#单选按钮，编码相同，但一个给出准确结果，另一个不'；T,c#,C#,当我将此值发送到文本框时，它会给出正确的值“9” private void radioButton1_CheckedChanged(object sender, EventArgs e) { if (smallPizza.Checked) { int smallPizzaPrice = 9; pizzaTotal += smallPizzaPrice; } } 当我将此值发送到同一

当我将此值发送到文本框时，它会给出正确的值“9”

 private void radioButton1_CheckedChanged(object sender, EventArgs e)
    {
        if (smallPizza.Checked)
        {
            int smallPizzaPrice = 9;
            pizzaTotal += smallPizzaPrice;
        }
    }

当我将此值发送到同一文本框时，我得到“21”

我有一个大比萨饼的代码，其中我将价格初始化为14，但值23被发送到文本框

代码的其余部分：

private void mediumPizza_CheckedChanged_1(object sender, EventArgs e)
    {
        if (mediumPizza.Checked)
        {
            int mediumPizzaPrice = 12;
            pizzaTotal += mediumPizzaPrice;
        }
    }

看起来，

pizzatottal

是表单的一个变量，控件位于。所以第一次值为0时，加9得到9。但当按下第二个按钮时，12被添加到先前的值9上。那就是21

尝试按相反方向的按钮，然后查看结果。

似乎

pizzaTotal

是表单的一个变量，控件位于。所以第一次值为0时，加9得到9。但当按下第二个按钮时，12被添加到先前的值9上。那就是21

试着反过来按按钮，看看结果。

你这样称呼它

如果您需要在每个代码>更新复选框中保持运行总数，请检查“处理程序”，您应该考虑“unChube”应该从总体上减去，即

private void calculateTotal_Click(object sender, EventArgs e)

    this.priceBeforeVat = this.CalculateTotal()
    costOfPizza.Text = string.Format("{0:C2}", this.priceBeforeVat)
