Question

出于某种原因，第一个＆＃34;如果＆＃34;声明在我调试时工作，但当我尝试任何其他单选按钮或使用相同的按钮但尝试制作第二个＆＃34;如果＆＃34;陈述是真的，我点击＆＃34;计算奖励积分＆＃34;按钮，但它不计算。它只计算第一个＆＃34; If＆＃34;声明。这是我的代码。如果我的行话没有达到标准，我道歉。我只参加这门课，因为它是必需的。我附上

Public Class Form1

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Const basic1 As Double = 0.03
    Const basic2 As Double = 0.05
    Const basic3 As Double = 0.08
    Const basic4 As Double = 0.1
    Const basic5 As Double = 0.15
    Dim totalLabel As Double
    Dim doubleReward As Double

    Double.TryParse(RewardDisplay.Text, doubleReward)
    Double.TryParse(TotalTextBox.Text, totalLabel)

    If basicRadioButton.Checked AndAlso totalLabel < 100 Then
        RewardDisplay.Text = totalLabel * basic1
    ElseIf basicRadioButton.Checked AndAlso totalLabel < 200 or >= 100 Then
        RewardDisplay.Text = totalLabel * basic2
    ElseIf basicRadioButton.Checked AndAlso totalLabel >= 200 Then
        RewardDisplay.Text = totalLabel * basic3
    ElseIf standardRadioButton.Checked AndAlso totalLabel < 199 Then
        RewardDisplay.Text = totalLabel * basic3
    ElseIf standardRadioButton.Checked AndAlso totalLabel >= 200 Then
        RewardDisplay.Text = totalLabel * basic4
    ElseIf premiumRadioButton.Checked AndAlso totalLabel < 299 Then
        RewardDisplay.Text = totalLabel * basic4
    ElseIf premiumRadioButton.Checked AndAlso totalLabel >= 300 Then
        RewardDisplay.Text = totalLabel * basic5
    End If
End Sub

您必须在调试模式下查看变量的值 basicRadioButton.Checked和totalLabel来理解为什么算法没有达到你期望的效果。简化您的代码，也许可以做一些链接这个
