VBA如果时间在两次之间

Question

i = 1    
For Each cell In Range("D1:D10000")
  If IsEmpty(cell.Value) Then Exit For

  Select Case Range("N" & i).Value
    Case 0 To 40
      startTime  = "13:00"
    Case 40 To 60
      secondTime = Range("V" & i).Value
    Case 60 To 100
      finalTime = Range("V" & i).Value
    Case Else

   End Select

  Dim startTime As Date
  Dim secondTime As Date
  Dim finalTime As Date
  Dim timeRef As Date
  timeRef = Range("V" & i).Value

  If timeRef >= startTime And timeRef < secondTime Then 

  ElseIf timeRef >= secondTime And timeRef < finalTime Then

  ElseIf timeRef > finalTime Then

  End If
  i = i + 1
Next

好的，所以我使用上面的方法来尝试比较格式为日期的时间。它们都是从自定义格式为“hh:mm”的工作表中获取的，但我似乎没有时间落在最后的elseif

啊！

您是在分配给它们之后声明这些值（startTime、secondTime 和 finalTime）。至少，您需要更改代码以声明然后分配。 （另外，你的第一个 if 语句是错误的；第一个测试应该只是 If timeRef < secondTime。）

' Declare variables before assigning values to them
Dim startTime As Date
Dim secondTime As Date
Dim finalTime As Date
Dim timeRef As Date

i = 1    
For Each cell In Range("D1:D10000")
  If IsEmpty(cell.Value) Then Exit For

  Select Case Range("N" & i).Value
    Case 0 To 40
      startTime  = "13:00"
    Case 40 To 60
      secondTime = Range("V" & i).Value
    Case 60 To 100
      finalTime = Range("V" & i).Value
    Case Else
      ' You should do something here; what if the cell is empty or invalid?
      ' You end up with no value assigned to anything when leaving the Select
   End Select

  timeRef = Range("V" & i).Value

  If timeRef < secondTime Then 

  ElseIf timeRef >= secondTime And timeRef < finalTime Then

  ElseIf timeRef > finalTime Then

  End If
  i = i + 1
Next

由于我没有要测试的任何数据，我不知道这是否真的有效，但它解决了阻止它工作的明显问题。
