在VBA中查找最后一行的差异

Question

我有3种方法可以找到col A中的最后一行。什么是差异？哪一个最好用。

Nr 1
Range("A" & Rows.Count).End(xlUp).Row

Nr 2
Cells.Find(What:="*", After:=Range("A1"), SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row

Nr 3
Dim Col, row, lastRow As Integer

Col = 1
row = 1
lastRow = 1

lastRow = Cells(Rows.Count, Col).End(xlUp).row
Cells(lastRow, Col).Select

Answer 1

获取列 A 中最后一个已填充单元格的行号的一种方法：

Sub LastFilledCellInColumnA()
    Dim wf As WorksheetFunction, nLastRowA As Long
    Set wf = Application.WorksheetFunction
    nLastRowA = Rows.Count
    If wf.CountA(Cells(nLastRowA, 1)) = 1 Then
        MsgBox nLastRowA
        Exit Sub
    End If
    nLastRowA = Cells(Rows.Count, "A").End(xlUp).Row
    MsgBox nLastRowA
End Sub

如果A列为空 1 将输出
