Vb.net 为什么变量不会上升
所以,既然我把它作为一个变量,即使它说I=3,它也不会继续问问题,我真的不知道还能做什么,I上升了,但问题没有。。 我知道我可能在这方面做得很差,但为什么直到5秒钟前它还有效,现在却没有Vb.net 为什么变量不会上升,vb.net,Vb.net,所以,既然我把它作为一个变量,即使它说I=3,它也不会继续问问题,我真的不知道还能做什么,I上升了,但问题没有。。 我知道我可能在这方面做得很差,但为什么直到5秒钟前它还有效,现在却没有 Public Class Test1 Dim question(3, 5) As String Dim i As Integer = 2 Dim correctanswear = 0 Dim a As Integer = 0 Private Sub Test1_Load() question(1, 0)

End Class每当用户输入正确答案时,必须调用Test1\u Load以更新问题 例如:
If i = 2 AndAlso nr4.Checked = True Then
correctanswear += 1
MessageBox.Show("You answered " + correctanswear.ToString() + " questions correctly.")
i = i + 1
MessageBox.Show(i)
Test1_Load()
ElseIf i = 3 AndAlso nr3.Checked Then
correctanswear += 1
MessageBox.Show("You answered " + correctanswear.ToString() + " questions correctly.")
i = i + 1
MessageBox.Show(i)
Test1_Load()
End If
另一方面,当用户得到正确答案时,可能值得将问题更新代码分解为Test1\u Load调用的函数,这样您就不必在每次测试中多次重新初始化问题数组。请解释您希望在标签中看到什么以及您看到什么。问题2+2=?尽管如此,消息框显示i=3,问题应该改变,它被卡住了。
