Vba 使用IsEmpty停止循环

我发现了一个线程，它直接应用于我试图在这里构建的代码

这段代码只有一个例外，它会不断循环

我认为

如果不是IsEmpty

将是VBA的描述符，一旦它到达列表的末尾就停止该程序。

关于我的评论，请尝试以下操作。这会快得多

Sub Test()
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim CurCell_1 As Range, CurCell_2 As Range
    Dim Group As Range, Mat As Range, Ran As Range
    Dim lRow As Long

    Set ws1 = ActiveWorkbook.Sheets("Scrap")
    Set ws2 = ActiveWorkbook.Sheets("FC Detail")

    With ws1
        lRow = .Range("E" & .Rows.Count).End(xlUp).Row

        Set Ran = .Range("E1:E" & lRow)

        For Each Mat In Ran
            Set CurCell_2 = ws2.Range("F8")
            For Each Group In Ran
                Set CurCell_1 = .Cells(Group.Row, Mat.Column)
                If Not IsEmpty(CurCell_2) Then
                    CurCell_2.Value = CurCell_1.Value
                End If
            Next
        Next
    End With
End Sub

你所说的“持续循环”是什么意思？如果代码从未退出循环，你怎么知道它“工作”呢？它持续运行是因为你正在寻址整个列。。。两次。为什么不找到最后一行，然后限制你的范围，如另一个链接所示？+1。Colin，如果您进行任何Excel VBA开发，那么查找最后一行将一直是您要做的事情。Siddharth在上面的代码中找到它的方式是你应该记住的。你还需要养成逐步浏览代码（F8）的习惯，看看它到底在做什么。说到好习惯，把DoEvents放在所有循环中，尤其是在开发过程中。这样，你就可以在无休止的循环中随时闯入。非常感谢你的帮助，经过一些修改，效果非常好。

Sub Test()
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim CurCell_1 As Range, CurCell_2 As Range
    Dim Group As Range, Mat As Range, Ran As Range
    Dim lRow As Long

    Set ws1 = ActiveWorkbook.Sheets("Scrap")
    Set ws2 = ActiveWorkbook.Sheets("FC Detail")

    With ws1
        lRow = .Range("E" & .Rows.Count).End(xlUp).Row

        Set Ran = .Range("E1:E" & lRow)

        For Each Mat In Ran
            Set CurCell_2 = ws2.Range("F8")
            For Each Group In Ran
                Set CurCell_1 = .Cells(Group.Row, Mat.Column)
                If Not IsEmpty(CurCell_2) Then
                    CurCell_2.Value = CurCell_1.Value
                End If
            Next
        Next
    End With
End Sub
