我正在尝试在检查chkInsurence时为每位乘客增加10%的保险,并且当未经检查时将其返回到相同的值。这是我的代码
Private Sub chkInsurance_CheckedChanged(sender As Object, e As EventArgs) Handles chkInsurance.CheckedChanged
If chkInsurance.Checked Then
price += CDec(price * 0.1) * nudPassengers.Value
Else
price -= CDec(price * 0.1) * nudPassengers.Value
End If
lblPrice.Text = price.ToString("C")
End Sub
当Else运行时,它需要当前值的10%并减去而不是原始值的10%。
答案 0 :(得分:0)
您可以将价格标签的值存储在变量中,当用户取消选中时,将存储的值分配给标签

我修改了另一个变量而不是Idle_Mind建议的价格
Private Sub chkInsurance_CheckedChanged(sender as Object,e As EventArgs)Handles chkInsurance.CheckedChanged
Dim insurenceTotal As Decimal
If chkInsurance.Checked Then
insurenceTotal = CDec(price + (price * 0.1) * nudPassengers.Value)
lblPrice.Text = insurenceTotal.ToString("C")
Else
lblPrice.Text = price.ToString("C")
End If
End Sub
