我创建了一个获取随机数的应用程序。但是,我的 IF 语句似乎不起作用,并且我不断提出重复的数字。
代码是:
公开课形式1
Dim number As Integer
Dim star As Integer
Dim getNumber As Random = New Random()
Dim getStar As Random = New Random()
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
If (number1.Text = number2.Text) Or (number1.Text = number3.Text) Or (number1.Text = number4.Text) Or (number1.Text = number5.Text) Then
If (number2.Text = number1.Text) Or (number2.Text = number3.Text) Or (number2.Text = number4.Text) Or (number2.Text = number5.Text) Then
If (number3.Text = number1.Text) Or (number3.Text = number2.Text) Or (number3.Text = number4.Text) Or (number3.Text = number5.Text) Then
If (number4.Text = number1.Text) Or (number4.Text = number2.Text) Or (number4.Text = number3.Text) Or (number4.Text = number5.Text) Then
If (number5.Text = number1.Text) Or (number5.Text = number2.Text) Or (number5.Text = number3.Text) Or (number5.Text = number4.Text) Then
number5.Text = CStr(getNumber.Next(1, 50))
number4.Text = CStr(getNumber.Next(1, 50))
number3.Text = CStr(getNumber.Next(1, 50))
number2.Text = CStr(getNumber.Next(1, 50))
number1.Text = CStr(getNumber.Next(1, 50))
Else
number5.Text = ""
End If
Else
number4.Text = ""
End If
Else
number3.Text = ""
End If
Else
number2.Text = ""
End If
Else
number1.Text = ""
End If
If (star1.Text = star2.Text) Then
If (star2.Text = star1.Text) Then
star1.Text = CStr(getStar.Next(1, 11))
star2.Text = CStr(getStar.Next(1, 11))
Else
star1.Text = ""
star2.Text = ""
End If
End If
End Sub
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
number1.Clear()
number2.Clear()
number3.Clear()
number4.Clear()
number5.Clear()
star1.Clear()
star2.Clear()
End Sub
End Class
谁能帮我解决这个问题?
谢谢
