我需要检查demical是0到49.99或50到99.99或100到199.99还是大于200.我试图用select case来做这个,但我不确定语法.请帮忙！
Select Case aa
Case 1 To 1.49
MsgBox(1)
Case 1.5 To 2
MsgBox(2)
Case Else
MsgBox("was lower than 1 or higher than 2 or between 1.49 and 1.5")
End Select
这(下面)将进入其他情况
Dim aa As Double = 1.499
这(下面)将进入案例1至1.49
Dim aa As Double = 1.4
这(下面)将进入案例1.5至2
Dim aa As Double = 1.78
其他方式：From here
Select Case value
Case Is <= 49.99
Debug.WriteLine("first group")
Case Is <= 99.99
Debug.WriteLine("second group")
Case Is <= 199.99
Debug.WriteLine("third group")
Case Else
Debug.WriteLine("fourth group")
End Select
也许这也是：
Select Case true
Case (value >= 0 andalso value <= 49.99)
Debug.WriteLine("first group")
Case (value >= 50 andalso value <= 99.99)
Debug.WriteLine("second group")
Case (value >= 100 andalso value <= 199.99)
Debug.WriteLine("third group")
Case Else
Debug.WriteLine("fourth group")
End Select
