如何在VB.net中存储和计算数学测验的分数?
我对VB很陌生,正在做一个小的学校项目,我正在做一个数学测验,当用户随机提出数学问题时,如果他们答对了问题,那么他们的分数将增加1,但我不知道如何计算分数。这是我目前掌握的代码:如何在VB.net中存储和计算数学测验的分数?,vb.net,Vb.net,我对VB很陌生,正在做一个小的学校项目,我正在做一个数学测验,当用户随机提出数学问题时,如果他们答对了问题,那么他们的分数将增加1,但我不知道如何计算分数。这是我目前掌握的代码: Public Class Form1 Dim Ans As Integer Dim Num As Integer Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles

Dim Num2 As Integer = Generator.Next(0, 15)
Dim Show As String = ""
Dim SumType As Integer = Generator.Next(1, 3)
If SumType = 1 Then
Show = Num1 & "+" & Num2 & "= ?"
Ans = Num1 + Num2
ElseIf SumType = 2 Then
Show = Num1 & "-" & Num2 & "= ?"
Ans = Num1 - Num2
ElseIf SumType = 3 Then
Show = Num1 & "*" & Num2 & "= ?"
Ans = Num1 * Num2
End If
Label4.Text = Show
End Sub
Sub CreateScore()
Dim Score As Integer
If Ans = Val(txtAnswer.Text) Then
Score = Score + 1
End If
If Score >= 10 Then
MsgBox("Well Done! You have completed the quiz!")
End If
lblScore.Text = Score
End Sub
Private Sub btnNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext.Click
Call CreateProblem()
txtAnswer.Text = ""
End Sub
Private Sub txtAnswer_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtAnswer.TextChanged
End Sub
Private Sub Label4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label4.Click
End Sub
Private Sub btnCheck_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCheck.Click
If Val(txtAnswer.Text) = Ans Then
MsgBox("Correct")
Else
MsgBox("Incorrect")
End If
Call CreateScore()
End Sub
End Class
把线移开
Dim Score As Integer
在全局级别,您对Ans和Num变量具有相同的属性。这样,存储在该变量中的值在调用CreateScore方法之间可用 当然,现在你有另一个问题了。当用户启动新测试时,您需要一种重置此值的方法。可能您应该添加一个按钮来清除该值并将其设置为零
这里是关于的相关文档好的,谢谢,伙计,明天我可能会遇到另一个问题:D
